CHAPTER TWO
Beneficial bacteria in the environment and their uses.
In today’s world, the environment and its related issues are steadily gaining a lot of importance. Some bacteria are helpful and are used to obtain balance in the environment.
It has been seen that helpful bacteria are useful in dissolving organic sludge from water, breaking down the growth of algae, reducing the various noxious odours such as hydrogen sulfide odours, reducing ammonia levels, promoting faster growth of fish in the water body and also defeating unhealthy bacterial growth in the water body.
2.0.1. Bacteria and soil
In an environment, all types of life occur in cycles. When a plant or animal dies, it is replaced by another and the cycle continues.

Acetic acid is used by muscle propionic acid helps the liver produce ATP and butyric acid which provides energy to gut cells and may prevent cancer.
Evidence also indicates that bacteria enhance the absorption and storage of lipids() and then facilitate the body to absorb neede vitamins like vitamin K. Another less favourable types of fermentation, proteolytic fermentation, breaks down protein like enzymes, dead hosts and bacterial cells, and collagen and elastin found in food and can produce toxins and carcinogens in addition to SCFAs. Thus, a diet lower in protein reduces exposure to toxins.
Beneficial flora increase the gut’s absorption of water, reduce counts of damaging bacteria, increase growth of human gut cells and stimulate growth of indegenous bacteria. Another benefit of SCFAs is that they increase growth of intestinal epithelial cells and control their proliferation and differentiation. They may also cause lymphoid tissue near the gut to grow. Bacterial cells alter intestinal growth by changing the expression of cell surface proteins such as sodium/ glucose transporter. In addition changes they make to cells may prvent injury to the gut mucosa from occuring.
Another important role of helpful gut flora is that they prevent species that would harm the host by colonising the gut, an activity termed as the “barrier effect”. Harmful yeasts and bacterial species such as Clostridium difficile(the over growth of which can cause
