What are some beneficial bacteria?

Answer 1

On Yahoo answers, there is a question similar to this that asks to give 5 examples of beneficial bacteria and details. The answerer answers this:

Bacteria involved in the nitrogen cycle:
Nitrogen fixing bacteria- In the nodules of legumes; converts free N into nitrates.
Bacteria of decay- Returns/recycles organic matter back into the earth.
Nitrifying bacteria- converts ammonia into nitrates.
Denitrifying bacteria- converts nitrates into free N

Also:
Coliform bacteria in the human large intestine- Breaks down wastes & produces some v

Answer 2

Some examples of helpful bacteria:

E.coli,Rhizobium,Streptomyces,Bifidobacteria(e.t.c)

Look these up on Google.com....the images....and it'll give some info. about it....

There are bacteria's that reduce dirrhea, are put in antibiotics, and kinds tnat even improve the taste of some foods.

Answer 3

I don't know many kinds of beneficial bacteria and I am trying hard to find some more kinds for my own study, but I will share what kinds I do know.

Some Beneficial Bacteria Are:

1. Staphylococcus epidermis

2. Lactobacilli

3. Bifidobacteria

4. Bacillus

5. Acidophilus

6. Denitrifying bacteria

7. Pseudomonas aeruginosa

8. Pseudomonas fluorescens 2-79

Benefits of microorganisms to humans:

Food

Microorganisms are involved in the production of food or are directly edible.

Examples: - Various types of yeast (a type of fungus): Used for the production of beer, bread, and cheese. spirulinais a blue green algae used as SCP (single cell protein) in human beings for their protein source.

Health

It may come as a surprise but there are several billion times more bacterial cells inside your body than there are human cells. They make up the human flora. Luckily, some live in a mutualistic relationship to you. That is, they receive something (generally nutrients) from you, but also give something in return. The presence of bacteria also inhibits the growth of potentially pathogenic bacteria (usually through competitive exclusion).

Examples: - Gut bacteria: synthesize vitamins such as folic acid, vitamin K and biotin, and they ferment complex indigestible carbohydrates.

---Of special note is E. Coli - innate to the gut of everyone, this bacteria is a major part of the immune system (you get sick when some other species' E. Coli enters your body).

Biotechnology

We have vastly developed or discovered direct uses for microorganisms in recent years. Modern biotechnology is often associated with the use of genetically altered microorganisms such as E. coli or yeast for the production of substances like synthetic insulin or antibiotics. Using the same process, a multitude of drugs are manufactured relatively cheaply, including human growth hormone, clotting factors for hemophiliacs, fertility drugs, erythropoietin and other drugs.

Biotechnological advances in agriculture also require the help of microorganisms. Transgenic plants can increase yield, reduce vulnerability to environmental and pathogenic stresses, improve taste and appearance and produce novel plant substances. To create transgenic plants, a vector, Agrobacterium, is required to transfer genetic material into the plant host.

Micro-organisms also naturally have desired products or effects. These include substances that fight human pathogens, insecticidal properties, and bio-degradation properties, to name a few.

In fact, advances in the understanding of biological phenomena, the science of Biology that facilitates medical, agricultural, and food advances, are not possible without model microorganisms including: E. coli, B. subtilis, Phage λ, Tobacco mosaic virus, and S. cerevisiae to name a few.

Medicine

As humans are eukaryotes, our genome is extremely difficult to truly decode due to processes such as exon shuffling, the genetic "junk" and likely dozens of other observed aspects of our genome.

Naturally, many people with genetic defects need a constant supply of medicines (diabetics will be used from here on out in this section). Creating insulin in a lab was very difficult before the onset of cDNA, which (long story made really really short) is placing the human insulin gene into yeast or another simple eukaryote. Thankfully, all eukaryotic cells "know" how to process our genome and human hormones can be made in vivo in laboratories in greater quantity than ever before

Ecology

Microbes are involved in cycling vital elements such as carbon and nitrogen, breaking down wastes and dead organisms into simpler substances plants can use in photosynthesis. Other species are at the base of the food chain, especially in aquatic ecosystems. Even pathogens have a role in controlling the populations of their host species.

Answer 5

Some beneficial bacteria include probiotics such as Lactobacillus and Bifidobacterium species, which help maintain a healthy gut microbiome and support digestion. Another beneficial bacteria is Nitrosomonas, which converts toxic ammonia into nitrites in the soil, aiding in plant growth. Additionally, Rhizobium bacteria form symbiotic relationships with leguminous plants, fixing nitrogen from the air into a form that the plants can use.

Answer 6

escherchia coli help in digestion.

and some bacteria help in retting fibre maing etc...........

churning of milk

making of antibiotics

Answer 7

E. Coli (Eschericia Coli) in the stomach.
