What are 6 helpful bacteria?

Question

Explain how each is helpful, what do they do?

Answer 1

Lactobacillus acidophilus performs many critical functions including inhibiting pathogenic organisms and preventing them from multiplying and colonizing, when present in sufficient numbers.



Bifidobacterium bifidum is a prominent probiotic microorganism that takes up residence primarily in the mucous membrane lining of the colon. B. bifidum prevents the colonization of invading pathogenic bacteria by attaching to the intestinal wall, crowding out and taking nutrients from these unfriendly bacteria and yeasts.



Lactobacillus rhamnosus is one of the most intensely studied probiotic strains. Its advantages in the treatment of gastrointestinal disorders are well documented. In laboratory animal studies, L. rhamnosus has been shown to inhibit the growth of colon tumors, especially when supplementation with L. rhamnosus is started before tumors were induced with a carcinogenic substance.



Lactobacillus salivarius has the unique ability to eradicate the dreaded Helicobacter pylori (H. pylori) bacteria which is now known to be the major cause of peptic ulcers. The H. pylori microorganism interferes with the normal defenses against stomach acid and/or produces a toxin that contributes to peptic ulcer formation.



Bifidobacterium longum is an abundant organism found in the large intestine. B. longum has been found to reduce the frequency of gastrointestinal disorders (diarrhea, nausea, etc.) during antibiotic use. Furthermore, in the Cancer Research Journal, researchers report that dietary intake of B. longum significantly inhibits the development and growth of colon, liver and breast cancers in laboratory animal models.



Lactobacillus casei is reported to have the most potent protective activity against the potentially lethal Listeria bacteria than any other beneficial bacteria. Reports in the medical journal Cancer Letters show that L. casei not only shows an inhibiting activity in tumor cells but it also has a beneficial stimulating activity in normal cells.



Lactobacillus lactis acts as a natural antibiotic, which reduces the ability of pathogenic bacteria to grow and cause infection. It is especially effective against the bacteria Listeria monorytogenes, which causes severe food poisoning.

Answer 2

Rhizobia are helpful soil bacteria that can process (or ‘fix’) nitrogen from the air and change it into a form that crops or trees can use.
Probiotics are helpful bacteria, naturally occurring in our gastro-intestinal tract and contributing beneficially to our health
Lactobacillus and escherichia coli K 12 are for food medicine.
That's all I know!!

Answer 3

1) Streptococcus thermophillus,
2) Lactobacillus bulgaricus
both for making cheese.

Answer 4

penicillium notatum -helpful in penicillin production
streptomyces griseus -helpful in streptomycin production
rhizobium-symbiotic nitrogen fixing bacteria

Answer 5

E. Coli bacteria.

It helps you digest food. :*)
