A brief review of nutritional studies for Penaeus monodon
Provedor de dados: 5
Autores: Liao, I; Liu, F.
In order to develop effective formulated for Penaeus monodon , sufficient information is needed on its nutritional requirements.
Unfortunately, research on this area has been very limited. This paper outlines the results of such research. Since data on the
nutritional requirements of P. japonicus are relatively well established, some of these data are also reviewed in this paper and are
used as a basis for assessing the nutritional requirements of P. monodon . Protein, lipid, carbohydrate, mineral and vitamin
requirements are evaluated from the parameters of growth survival and feed efficiency. Studies on the effects of enzymes and the
development of microparticulate diet for larvae are also summarized.

Activation of nitrate reductase of cashew leaf by exogenous nitrite
Provedor de dados: 61
Autores: Viégas,Ricardo Almeida; Silveira,Joaquim Albenísio Gomes.
Nitrate reductase (NR) plays a central role in plant primary metabolism and exhibits complex regulation mechanisms for its
catalytic activity. There is controversy in the literature concerning the possible direct effect of NO2- on the stimulation and/or
activation of NR activity. The influence of NO2- was studied on the NR activity in the leaves of 30-day-old cashew (Anacardium
occidentale L.) seedlings. Addition of NO2- to the reaction mixture containing leaf enzymatic extract resulted in a remarkable
increase in NR activity. A trace amount (5 mumol.L-1) of NO2- was required to achieve full NR activity. The in vitro NR-activity
showed a steady time-dependent increase when incubated in the presence of only NO3- + NO2-. In contrast, in vitro NR activity
was...

Activity of cellulase from Thermoactinomycetes and Bacillus spp. isolated from Brassica waste
compost
Provedor de dados: 63
Autores: Chang,Chen-Chin; Ng,Chang-Chai; Wang,Chung-Yi; Shyu,Yuan-Tay.
Plant wastes present a high cellulose content, which is an ideal organic material for composting. Five strains of thermophiles from
processed Brassica waste were isolated, and the hydrolytic activity on various cellulosic biomass substrata and their temperature
profiles were determined. 16S rRNA sequencing identified these strains as Thermoactinomyces and Bacillus spp. Maximal
cellulase activity corresponded to 2.3 U mL-1 of enzyme. The application of these strains on Brassica rapa residues demonstrates
increased total nitrogen content). TA-3, a Thermoactinomycetes sp. strain, performs best among all inoculants, increasing the
nitrogen content from 0.74 to 0.91%, and decreasing the carbon content from 15.4 to 12.2%, showing its high efficiency and...

Background: Enzymes belonging to the same super family of proteins in general operate on variety of substrates and are inhibited
by wide selection of inhibitors. In this work our main objective was to expand the scope of studies that consider only the catalytic
and binding pocket amino acids while analyzing enzyme specificity and instead, include a wider category which we have named
the Interface Forming Residues (IFR). We were motivated to identify those amino acids with decreased accessibility to solvent
after docking of different types of inhibitors to sub classes of serine proteases and then create a table (matrix) of all amino acid
positions at the interface as well as their respective occupancies. Our goal is to establish a platform for analysis of...

Anatomy and physiology of digestive tract of crustaceans decapods reared in aquaculture
Provedor de dados: 5
Autores: Ceccaldi, H.
The digestive tract of crustacea is complex. It is composed of a shor t oesophagum, a stomach with two bags, and internal wall
with appendags specialized in grinding of feeds. These hard mastication pieces represent the gastric mill. Setae, filters included in
the stomach structure allow the separation between food particles and liquid compounds. Those one are coming over through
filters and more on to the digestive gland tubules or mid gut gland. In this organ, several types of cells play specialized functions:
absorption, enzyme secretion, stocking function. Some cells of a new type, with undefined function, may be neurosecretions
function, have been described recently. The end of tubules of digestive gland exhibits cells with embryonic characteristics....

Antioxidant system response induced by aluminum in two rice cultivars
Provedor de dados: 61
Autores: Ribeiro,Cleberson; Cambraia,José; Peixoto,Paulo Henrique Pereira; Fonseca Júnior,Élcio Meira da.
The antioxidant defense system response was evaluated in two rice cultivars (Oryza sativa L.), Fernandes (CNA-1158) and
Maravilha (CNA-6843-1), treated with toxic levels of aluminum. After exposure to aluminum we determined plant growth, H2O2
and O2•- contents, lipid peroxidation, antioxidant enzymes activities and ascorbate and dehydroascorbate contents.
Al predominantly accumulated in roots of both cultivars but it reduced root and shoot growth only in the Maravilha cultivar.
Treatment with aluminum resulted in a reduction of 84 and 60% in the levels of H2O2 in the roots of the cultivars Maravilha and
Fernandes, respectively, and of 26% in the levels of O2•- only in the roots of Fernandes cultivar. Increased lipid

The mechanism that bivalve molluscs react to infectious agents are important research subjects in the fIeld of disease control
studies for these animals. While the selection of disease resistant populations have made decisive progression in some species, the
mechanism behinds these resistant phenomena is not yet clear so far. However, hemocytes must represent one of the key factors in
the reaction process. Based on this hypothesis, the structure and function of European flat oyster, Ostrea edulis, hemocytes have
been investigated in aid of different techniques in the present study. ln addition, Pacific oyster, Crassostrea gigas, hemocytes have

Diversos trabalhos têm procurado aumentar a eficiência da hidrólise enzimática da biomassa lignocelulósica. Nesse contexto, o
melhoramento de cepas produtoras de enzimas celulolíticas e hemicelulolíticas pode resultar em misturas enzimáticas mais
eficientes. A linhagem parental de Aspergillus niger 3T5B8, referenciada como produtora de poligalacturonase, foi utilizada para
o melhoramento genético visando aumentar a produção de celulases e hemicelulases. A produção das enzimas CMCase, xilanase,
beta-glicosidase e poligalacturonase por fermentação submersa usando duas linhagens mutantes P49 e P83 foi avaliada e
comparada com a linhagem parental. Os resultados mostraram um destaque para a cepa P83 com um aumento na produção de
56% de CMCase, 76% de...

Autores: Boucaud, C; Lebesnerais, C; Lubet, P; Lihrmann, I.
Feeding experiments carried out on Crassostrea gigas allowed the authors to set up the stages and the timing of the movement of
food throughout the digestive tract. Various activities involved in digestion (glycosidases, esterases, and peptidases) were
investigated histochemically in the digestive tract in order to localize the sites of absorption and the sites of protein and
carbohydrate digestion. An explicative model of the different stages of digestion is proposed.

Early weaning of marine fish larvae onto microdiets: Constraints and perspectives
Provedor de dados: 5
Autores: Person, L.
Weaning small sized marine fish larvae at first feeding directly onto compound pellets is still difficult, while good results can be
obtained when used in combination with live prey or when a prefeeding period on live prey is provided up to a size of about 2-3
mg. Microdiets are generally well ingested as their acceptability and visual detection may be improved using feeding activators
and increasing good perception contrast. In theory, food may be processed to have a correct nutritional balance, selection of high
digestible components is very important as larval digestive system is not fully functional during the first 2 or 3 weeks of life.

The antifouling potential of commercial hydrolases, four proteases, seven glycosidases and one lipase was evaluated on the
adhesion of marine Pseudoalteromonas sp. D41. The experimental method, adapted to screen antifouling agents, was based on
bacterial adhesion in natural sterile sea water in a microtiter plate and on total biomass quantification by the fluorescent dye DAPI
(4[prime]6-diamidino-2-phenylindole). Savinase (subtilisin) was the most effective hydrolase in both the prevention of bacterial
adhesion and the removal of adhered bacteria. However, some enzymatic preparations tested such as Amano protease were not
only ineffective but also increased the number of adhered bacterial cells. Enumeration using epifluorescence microscopy of CTC...

Environmental and physiological factors that affect the efficacy of herbicides that inhibit the enzyme
protoporphyrinogen oxidase: a literature review
Provedor de dados: 87
Autores: Matzenbacher,F.O.; Vidal,R.A.; Merotto Jr.,A; Trezzi,M.M.
Herbicides that inhibit the enzyme protoporphyrinogen oxidase (PROTOX) are usually effective to control dicotyledonous weeds
and their agronomic efficacy is affected by environmental and physiological factors. The objective of this review is to summarize
the knowledge of those factors available in the scientific literature in the last decade. Environmental factors that influence
PROTOX inhibitors include temperature, irradiance and relative humidity. The most relevant physiological factors are the activity
of enzymes that can detoxify herbicides and also of enzymes that mitigate the effects of oxidative stress in plants. The study also
suggests some possible management strategies that could optimize the activity of PROTOX-inhibiting herbicides.

Enzymatic activities for digestion of proteins and carbohydrates were compared among three organs of the digestive system of
Pimelodus maculatus in two reservoirs with different trophic conditions during the winter of 2006. The aim was to test the
hypothesis that enzymatic activity for the digestion of proteins and carbohydrates differed among organs and that such activities
differ between the trophic state of the environment. Enzymatic activities were determined through the assays of specificity for
trypsin, chymotrypsin and β-glucosidase enzymes. The intestine had higher trypsin-like enzymatic activities compared

Bungarus flaviceps (red-headed krait) venom presents an intravenous LD50 of 0.32 μg/g and exhibits enzymatic
activities similar to other Bungarus toxins. ELISA cross-reactions between anti-Bungarus flaviceps and a variety of elapid and
viperid venoms were observed in the current study. Double-sandwich ELISA was highly specific, since anti-B. flaviceps serum
did not cross-react with any tested venom, indicating that this assay can be used for species diagnosis in B. flaviceps bites. In the
indirect ELISA, anti-B. flaviceps serum cross-reacted moderately with three different Bungarus venoms (9-18%) and Notechis

enzyme programs at different ages. Trial 1- The body weight gain (BWG) was affected by the Negative Control (NC) treatment
(P<0.05). However, when the birds were fed with the NC diet + Amilase (AMY)+Xilanase (XYL), the BWG improved and
reached the same level as the Positive Control (PC). Trial 2- The birds received enzymes supplementation in the total phase and
others only in the grower phase.The ME reduction by 120 kcal/kg increased the feed conversion ratio (FCR) (P<0.05) when
compared to PC and none of the enzyme programs was able to recover the performance. It can be concluded that it is possible to
supplement with AMY...

The aim of this study was to evaluate the performance of Patagonian octopus fed with moist diets formulated with several local
feed ingredients. All formulated diets were based on crab paste (70%) and the experimental feed ingredient (30%). Experiment I
assayed salmon meal, prime sardine meal, and wheat gluten, using fresh fish as a control; experiment 2 assayed prime fish meal
and macroalgal meal against crab paste alone as a control. The ingestion rate was lower than expected for all diets except those of
fresh fish, crab paste alone, and crab paste plus prime sardine meal. No significant differences were found in the observed
digestibility of the diets, indicating, in general, low digestibility, even for fresh fish. The highest protease values were...

Hymenoptera venoms are complex mixtures containing simple organic molecules, proteins, peptides, and other bioactive
elements. Several of these components have been isolated and characterized, and their primary structures determined by
biochemical techniques. These compounds are responsible for many toxic or allergic reactions in different organisms, such as
local pain, inflammation, itching, irritation, and moderate or severe allergic reactions. The most extensively characterized
Hymenoptera venoms are bee venoms, mainly from the Apis genus and also from social wasps and ant species. However, there is
little information about other Hymenoptera groups. The Apis venom presents high molecular weight molecules - enzymes with a

Sphingomyelinases D (SMases D) or dermonecrotic toxins are well characterized in Loxosceles spider venoms and have been
described in some strains of pathogenic microorganisms, such as Corynebacterium sp. After spider bites, the SMase D molecules
cause skin necrosis and occasional severe systemic manifestations, such as acute renal failure. In this paper, we identified new
SMase D amino acid sequences from various organisms belonging to 24 distinct genera, of which, 19 are new. These SMases D
share a conserved active site and a C-terminal motif. We suggest that the C-terminal tail is responsible for stabilizing the entire
internal structure of the SMase D Tim barrel and that it can be considered an SMase D hallmark in combination with the amino

Microbial pectinolytic enzymes are known to play a commercially important role in a number of industrial processes. Two kinds
of yeast can be discerned regarding the production of enzymes. One group includes those which can produce enzymes in the
absence of an inducer, and the other group comprises the yeasts that produce enzymes in the presence of an inducer. The objective
of this study was to investigate the influence of pectic substances, glucose, pH, and temperature on the polygalacturonase activity
by Kluyveromyces marxianus CCMB 322. The yeast was grown in a fermentation broth containing different concentrations of
glucose and pectic substances. The polygalacturonase activity was determined by the DNS method, and the pH and temperature

Recent results have demonstrated that live yeast in diets improved gut maturation in sea bass larvae. In this study, we tested the
absence and two levels of live yeast in sea bass larvae diets. Specimens were fed from time of mouth opening to 37 days after
hatching a diet of 0%, 1.1%, or 5.7% wet weight of live yeast (Debaryomyces hansenii CBS 8339). Yeast incorporation improved
survival 10%, and reduced malformed larvae. In groups fed 1.1% yeast, only 1% of larvae were malformed, compared to 14% in
the control group. Final mean weight in groups fed 1.1% yeast was twice that of other groups. Activities and concentrations of

The impact of supplemental UV-B (sUV-B) radiation and heavy metals: Cd (68 µmol.kg-1 soil) and Ni (68 µmol.kg-1 soil) singly
and in combination was studied on photosynthetic and non-photosynthetic pigments, metabolites, enzyme activities, biomass
accumulation and the net primary productivity of spinach (Spinacia oleracea L. var. All Green), a common leafy vegetable plant.
Both the stresses individually and in combination resulted in the reduction of photosynthetic pigments, ascorbic acid, and catalase
activity, whereas a reverse trend was observed for anthocyanin, flavonoids and proline content, lipid peroxidation and peroxidase
activity. The interactive effects of both the stresses were, however, less than additive. Combined treatment of sUV-B + Cd was...

Abstract: The mangrove ecosystem is a coastal tropical biome located in the transition zone between land and sea that is
characterized by periodic flooding, which confers unique and specific environmental conditions on this biome. In these
ecosystems, the vegetation is dominated by a particular group of plant species that provide a unique environment harboring
diverse groups of microorganisms, including the endophytic microorganisms that are the focus of this study. Because of their
intimate association with plants, endophytic microorganisms could be explored for biotechnologically significant products, such
as enzymes, proteins, antibiotics and others. Here, we isolated endophytic microorganisms from two mangrove species,

In this paper, we describe the enzyme levels and isozyme distribution in skeletal and heart muscle of Satanoperca aff. jurupari,
(Cichlidae, subgroup Geophaginae). LDH and CS were measured in skeletal and heart muscle. Starch gel electrophoresis was used
to determine the isozyme/allozyme patterns in different tissues; LDH, MDHs, PGM, PGI, ADH, G-6-PDH and SOD were
screened for the numbers of loci, presence of alleles, and tissue specificity. The LDH/CS ratio in heart and skeletal muscle were
173.36 and 6.1, respectively, indicating anaerobic metabolism in the former and aerobic metabolism in the latter muscle. No
inhibition by pyruvate (based on the ratios of LDH activity with 1 mM and 10 mM pyruvate) was detected in heart and skeletal

Metabolic responses of channel catfish (Ictalurus punctatus) exposed to phenol and post-exposure
recovery
Provedor de dados: 42
Autores: Moraes,Fernanda D.; Rossi,Priscila A.; Figueiredo,Juliana S.L.; Venturini,Francine P.; Cortella,Lucas R.X.;
Moraes,Gilberto.
Metabolic adjustments were studied in channel catfish Ictalurus punctatus exposed to 1.5 mg L-1 of phe nol (10% LC50) for four
days and recovered for seven days. Lower triacylglycerol (TGA) stores and increased muscle fat free acids (FFA) suggest fat
catabolism in muscle. Remarkable liver FFA decrease (-31%) suggests liver fat catabolism as well. Increased muscular ammonia
levels and ASAT (aspartate aminotransferase) and decreased plasma aminoacids suggest higher muscular amino acid uptake.
Constant levels of glucose and increased liver glycogen stores, associated with lower amino acids in plasma, indicate
gluconeogenesis from amino acids. This is supported by higher hepatic ALAT and ASAT. Higher hepatic LDH followed by lower
plasma lactate may indicate...

Abstract: In this study, a Bionectria sp. strain isolated from citrus rhizosphere was evaluated for its potential in inhibiting the
growth of Rhizoctonia solani and Pythium aphanidermatum. It was demonstrated that Bionectria sp. 6.21 inhibited the growth of
P. aphanidermatum and R. solani. In dual cultures, however, the antagonist only parasitised R. solani. Regarding the assay
involving P. aphanidermatum, a lack of mycoparasitic ability was demonstrated. Crude extract of Bionectria completely inhibited
the mycelial growth of both fungi. It appears that the main mechanism involved in the antagonism of Pythium by Bionectria is
through antibiotic production. The antagonistic fungus released extracellular secondary metabolites. The metabolites were found

Provedor de dados: 69
Autores: Martínez,Claudio; Gertosio,Cecilia; Labbe,Angelica; Pérez,Rafael; Ganga,Maria Angélica.
Rhodotorula glutinis is a yeast that secretes the enzyme alpha-L-arabinofuranosidase (E.C. 3.2.1.55) into the culture medium and
thus has an interesting biotechnological potential. To determine improved culture conditions of this organism, different factors of
the culture media were evaluated such as the use of peptone as nitrogen source, salts composition, pH and growth temperature.
Likewise, beet molasses and beet cosette were tested as industrial carbon sources to induce the production of the enzyme and how
they influence the yeast growth. Based on these studies a culture medium is proposed for growth of this yeast in a continuous
system. By assaying different dilution rates an average specific activity for the enzyme of 82.4 U/mg of protein was obtained.

Paiva; La Selva,Marcelo; Chitarra,Adimilson Bosco.
The goal of this work was to evaluate the effect of different storage temperatures on the quality maintenance of fresh-cut 'Fortuna'
avocado (Persea americana Mill.). The fruit was selected, washed and sanitized with sodium hypochlorite solution (190 ppm total
residual chlorinee) for 15 minutes. After that, the tip was cut and the fruit was also cut in halves, peeled and the pit removed,
manually. Then the halves were immersed in 0.5% calcium chlorite + 0.5% cysteine solution for 2 minutes, to avoid darkening
and packed in rigid plastic covered with 20 micrometer thick plastic wrap (PVC film) with a permeability to O2, CO2 and water
vapor of 15,000, 80,000 and 390 cm³/m²/day, respectively. The product was stored under 3 different temperatures 0, 5, 10ºC...

Relations between bacterial extracellular enzyme activities and heterotrophic substrate uptake in a
brackishwater environment.
Provedor de dados: 5
Autores: Hoppe, H.
Extracellular enzymes mediate the decomposition of polymeric organic compounds in natural waters. In many cases these
enzymes comprise a component linked to the bacterial fraction of the aquatic community and react in close association with these
cells. An annual survey of microbial activities in a brackish water fjord exhibited an excellent correlation between V sub(m) of
proteases (ability to split the substrate analogue methylumbelliferyl-leucine) and V sub(m) as well as T sub(R) for leucine uptake
by microorganisms. Hydrolysis rates (H sub(R)) for the decomposition of naturally occurring competitive substrate analogues of
the model substrates (methylumbelliferyl-(MUF)-leucine, MUF- alpha -D-glucose, MUF-N-acetyl-glucosamine, MUF-phosphate)

ROLE OF ENZYMES IN THE REMEDIATION OF POLLUTED ENVIRONMENTS
Provedor de dados: 126
Autores: Rao,M.A; Scelza,R; Scotti,R; Gianfreda,L.
Environmental pollution is growing more and more due to the indiscriminate and frequently deliberate release of hazardous,
harmful substances. Research efforts have been devoted to develop new, low-cost, low-technology, eco-friendly treatments
capable of reducing and even eliminating pollution in the atmosphere, the hydrosphere and soil environments. Among biological
agents, enzymes have a great potentiality to effectively transform and detoxify polluting substances because they have been
recognized to be able to transform pollutants at a detectable rate and are potentially suitable to restore polluted environments. This
brief review will examine some classes of pollutants and enzymes capable of transforming them effectively into innocuous
products....

The effects of varying temperatures (12 - 44° C) on the specific activity of cytoplasmic malate dehydrogenase ((cMDH),
mitochondrial malate dehydrogenase (mMDH) and lactate dehydrogenase (LDH) of some earthworms (Metaphire posthuma,
Perionyx sansibaricus and Lampito mauritii) were studied. The effects of different temperatures on supernatant and mitochondrial
protein contents were also investigated. The specific activities of cMDH, mMDH and LDH of the earthworms decreased gradually
as a function of increasing temperature from 12 to 44°C. Higher metabolic energy was needed to maintain the activity at low
temperatures. Hence, the earthworms showed increased enzyme specific activity at low temperatures. However, the protein
content increased upto 28°C....

Thermotolerant fermenting yeasts for simultaneous saccharification fermentation of lignocellulosic
biomass
Provedor de dados: 69
Autores: Choudhary,Jairam; Singh,Surender; Nain,Lata.
Lignocellulosic biomass is the most abundant renewable source of energy that has been widely explored as second-generation
biofuel feedstock. Despite more than four decades of research, the process of ethanol production from lignocellulosic (LC)
biomass remains economically unfeasible. This is due to the high cost of enzymes, end-product inhibition of enzymes, and the
need for cost-intensive inputs associated with a separate hydrolysis and fermentation (SHF) process. Thermotolerant yeast strains
that can undergo fermentation at temperatures above 40°C are suitable alternatives for developing the simultaneous
saccharification and fermentation (SSF) process to overcome the limitations of SHF. This review describes the various approaches
to screen and develop...

Two related thrombin-like enzymes present in Bothrops atrox venom
Provedor de dados: 56
Autores: Petretski,J.H.; Kanashiro,M.; Silva,C.P.; Alves,E.W.; Kipnis,T.L.
This article describes the presence of two new forms of a thrombin-like enzyme, both with apparent molecular masses of 38 kDa,
in Bothrops atrox venom. Both share the ability to cleave fibrinogen into fibrin and to digest casein. Both present identical Km on
the substrate BApNA. Their N-terminal amino acid sequences are identical for 26 residues, sharing 80% homology with
batroxobin and flavoxobin. Two groups of monoclonal antibodies (mAbs) raised against the purified enzyme forms recognized
different epitopes of the putative corresponding enzymes present in B. atrox crude venom. On Western blotting analysis of B.
atrox crude venom, mAbs 5DB2C8, 5AA10 and 5CF11, but not mAbs 6CC5 and 6AD2-G5, revealed two or more protein bands
ranging from 25 to 38 kDa. By...

VCP1 PROTEASE DETECTION IN Pochonia chlamydosporia var. CATENULATA STRAIN IMI
SD 187
Provedor de dados: 100
Autores: Peteira-Delgado,B; Hidalgo-Díaz,L.
The mode of action of Pochonia as a biological control agent is the penetration by means of the hyphae into the target nematode
eggs. The egg shell of nematodes has an outer vitelline membrane composed mainly by proteins. Thus, hyphal penetration is the
result of a physic pressure and the specific hydrolytic activity of some enzymes such as proteases and chitinases. The most
important protease studied in Pochonia chlamydosporia var. chlamydosporia is VCP1. The aim of this work was to detect and
characterize the protease VCP1 in a strain of P. chlamydosporia var. catenulata, a potential biological control agent for root-knot
nematodes. The specific activity of this protease was tested on different culture media supplemented with protein inductors
