Helpful bacteria such as Streptococcus salivarius ssp thermophilus and Lactobacillus delbrueckii ssp. bulgaricus are used as cultures to produce yogurt, and other bacteria are used to make cheese. Helpful bacteria are also present in the human digestive tract, where they are collectively called "gut flora." The average human has ten times as many gut flora individuals as cells in his or her own body, and the gut flora includes at least 300 different species.
(Note that penicillin is not a bacteria, but a chemical product of penicillium fungi.)

First consider all the jobs of bacteria. All cheeses are made by bacterial action on milk. There are other milk products like yogurt and the other fermented products. Saurkraut is a fermented product. There are decomposing bcteria that are very helpful. There is nitrifing bacteria that takes nitrogen from the air for plants to use. There are bacteria in the stomach of cows that help them digest their food. There are more. Check names on google.

The "friendly" bacteria called acidophilus help create a healthy environment within the gastrointestinal tract. Taking acidophilus may combat digestive disorders, control vaginal yeast infections, and help the body resist diseases caused by "unfriendly" bacteria.
Yogurt, the traditional source of acidophilus

- Lactobacillus acidophillus
- Bifidobocterium bifidum
- Bacillus licheniformis
- Bacillus subtilis
- Lactobacillus lactis
- Lactobacillus bulgaricus
These are good bacteria in a healthy GI tract. You can easily find them in an immune booster or probiotic on nutritional websites.

Bacteroides, clostridium, fusobacterium, eubacterium, ruminococcus, peptococcus, peptostreptococcus and bifidobacterium that help you digest your food come to mind...
And then there are those genetically altered bacteria that produce insuling and other drugs.
