here is part of a web page:
In the large intestines, trillions of bacteria and fungi excrete a variety of digestive enzymes. Of course, some of these bacteria and fungi moved into the large intestines from the small intestines, and others simply live in the colon. Certain helpful bacteria, known as "bifidobacteria", normally live in a healthy person's colon. Like the "lactobacilli" bacteria (previously mentioned), these bifidobacteria help to digest certain foods, create certain nutrients, and protect the large intestines from certain types of harmful bacteria, fungi, viruses, protozoa, and parasitic worms. Large amounts of water, some minerals, and other nutrients are absorbed through the large intestine walls, and into the blood stream and lymphatic fluid. What remain in the large intestines are mostly some living and some dead bacteria and fungi. There is also a little water, and some unabsorbed nutrients present. This mixture of bacteria, fungi, water, and some nutrients, is known as "stool", and it remains in the colon until it is passed out the anus, when the person goes to the bathroom.
Try doing a web search for types of helpful bacteria.

First thing I would ask, define helpful bacteria. Helpful where? In your digestive system? In manufacturing? In food preparation? There are lots of places helpful bacteria are located.
For example, Acidophilus and Bifidus are commonly added to yogurt. Adding these bugs helps keep your digestive tract healthy. Especially if you are on antibiotics or have diahrrea.
If you want to narrow your research to this aspect. Try searching the phrase "probiotics"

Bacteroides fragilis
Other gut flora
Bifidobacterium
Lactobacillus
I can't say I think much of your searching technique if all it takes is to go to google and type in "helpful bacteria"
There's a strain of pseudomonas to help clean up toxic groundwater (abc.net)
There's another strain of some lactic acid bacteria to help keep your veggies fresh
Bacteria are used to make cheese and yoghurt

Streptomyces-found worldwide in soil and are important in soil ecology. Streptomycetes are also of medical and industrial importance because they synthesize antibiotics.
Lactobacillus- species are used industrially for the production of yogurt, cheese, sauerkraut, pickles, beer, wine, cider, kimchi and other fermented foods, as well as animal feeds, such as silage.
