Probiotik Definition
• In general, Probiotics are live micro-organisms (in
most cases, bacteria) which are found identical to
helpful micro-organisms found in the human
intestine.
• According to the currently adopted definition by Food
and Agriculture Organization /World Health
Organization, probiotics are: ‘Live microorganisms
which when administered in adequate amounts
confer a health benefit on the host’.
• Probiotics are available in foods and dietary
supplements (for example, capsules, tablets,
and powders) and in some other forms as
well.
• Examples of foods containing probiotics are
yogurt, fermented and unfermented milk,
miso, tempeh, and some juices and soy
beverages
Types of Probiotic Bacteria
* Good Bacteria
Examples Bifidobacterium, Eubacterium, and
Lactobacillus (Lactic acid bacteria).
* Bad or Pathogenic Bacteria
Examples Clostridium, Salmonella, Shigella,
and Candida.

Characteristics of good bacteria that can be used as probiotic agent,
including:
1.
2.
3.
4.
5.
Having antimicrobial activities
Resistant to digestion tract selection system
Having anti carcinogenic activities
Able to colonize in the intestinal tract
Able to improve intestinal absorption
Main functions of probiotic food :
•
•
•
•
Maintain a balance of intestinal
bacteria
Reduce blood cholesterol level
Prevent the formation of cancer cells
Helps the digestion of lactose (sugar
in milk)
Benefits of Probiotics
1. Maintaining a balance between pathogenic
bacteria and good bacteria in the intestine
2. Help clean up the tract and produce
vitamins
3. Help liver function in detoxifying
4. Prevent diarrhea, constipation and allergies
5. Reduce the possibility of allergic reactions
6. Probiotik overcomes human indigestion
problem
7. Prevents IBS ( Irritable bowel syndrome)
8. Increase the system’s immunity
The beneficial bacteria in the alimentary tract, including
•
•
•
•
•
Lactobacilus acidophilus
Lactobaciluus casei
Bifidobacterium bifidum
Bifidobacterium langum
Saccharomyces boulardii
:
•
Lactobacillus bulgaricus
Lactobacillus casei
Bifidobacterium
Examples of pathogenic bacteria in the alimentary tract:
1. Staphylococcus aureus
2. Salmonella : causes enteric fever and
gastroentritis
3. Shigella : causes shigellosis (Basher
dysentery)
4. Vibrio cholerae
5. Clostridium botulinum
6. Pseudomonas cocovenenans

Conclusion
Probiotics are bacterias that are helpful to
the human health especially for the human
digestive system. Consumption of
Probiotics will help the digestive system
to funtion at its best.
