Three Beneficial Bacteria

Lactobacillus is acid-resistant and tolerates bile very effectively. This bacteria lives in our digestive, urinary, and genital systems without causing any diseases. The lactobacillus is used for treating and preventing diarrhea.It is also used for skin disorders such as fever blisters, canker sores, eczema (allergic dermatitis) and acne. It is great towards high cholesterol, lactose intolerance, Lyme disease, hives, and to boost the immune system. If children have lung infections and if you give them lactobacillus, then the children will have fewer and less severe lung infections. If given lactobacillus, children will have less experience with diarrhea when they take antibiotics.

Ruminococcus is a non-motile organism with a coccoid shape. They are anaerobic bacteria and must obtain nutrients by breaking down cellulose and they are capable of fermenting glucose. Ruminococcus inhabits the rumen cattle, sheep, and goats. This is a beneficial bacteria towards farmers because farmers will be able to make advances in animal productivity. It helps in the digestion of cellulose. Without the ruminococcus, cattles will not be healthy and they will not be able to properly digest grasses and grains.

Bacillus thuringiensis is a bacteria that produces crystals protein, also known as cry proteins, which are toxic to many insect species. Bacillus thuringiensis is used for agriculture such as organic farming, urban aerial spraying programs, and in transgenic crops. It is safe in the environment for mammals and the EPA has not found any related threats or dangers caused by this bacteria towards humans. Once eaten by the insect, the toxin blinds to specific receptors in the gut, causing the insect to stop eating. This is potentially helpful towards to the plants because there will not be as much damage as if could have had if the insects had continued eating away at the plant. Because of this bacteria, farmers have to be careful when matching up which insects and which Bacillus thuringiensis toxin. This is beneficial towards the insects because they will not be harmed as much although the insects will die in a couple of days and not immediately.
