NMEICT-MHRD (Govt. of India) Project on - Creation of e-Contents on Fermentation Technology Module-6: Primary and Secondary screening Question banks Define the following terms Screening Primary screening Secondary screening Answers the following Exemplify primary screening of amylase producing microorganisms Exemplify primary screening of cellulase producing microorganisms Exemplify primary screening of organic acid producing microorganisms Exemplify primary screening of antibiotics producing microorganisms Exemplify primary screening of vitamins producing microorganisms Exemplify primary screening of amino acids producing microorganisms Exemplify primary screening of growth factor producing microorganisms Exemplify primary screening of microorganisms that utilize specific carbon source Exemplify primary screening of microorganisms that utilize specific nitrogen source Enlist criteria of secondary screening What is the strategies for isolation of industrially important microbes Enlist criteria used for choice of organisms Statefollowing statements are TRUE or FALSE 1. Secondary screening should be qualitative or quantitative in its approach 2. Secondary screening should not give information about the evaluation of the true potential of the microorganisms for industrial usage 3. Secondary screening should not determine whether microorganisms are actually producing new chemical compounds not previously described 4. Secondary screening should reveal whether there is pH, aeration or other critical requirements associated with particular microorganisms, both for the growth of the organism and for the formation of chemical products 5. It is not important for any organisms which is to be employed for production purpose to have genetic stability and its amenability to genetic manipulation Project control No: RE-02091011297, Christ College, Rajkot, Gujarat, India NMEICT-MHRD (Govt. of India) Project on - Creation of e-Contents on Fermentation Technology 6. Industrially important stain need not to have high yielding capacity 7. Industrially important strain should have stable biochemical characteristics 8. Industrially important strain should not produce undesirable substances 9. Industrially important strain should be easily cultivated Project control No: RE-02091011297, Christ College, Rajkot, Gujarat, India
