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. Decomposition occurs when a plant or animal dies. This is the process in which dead organisms are broken down to their basic elements. Streptomycetes are bacteria essential to decomposition found naturally in soil and are responsible for breaking down decaying plant and animal matter. Without this bacteria, dead matter would quickly build up throughout the environment. The process of the breakdown by streptomycetes releases nutrients into the soil, which allows new life to grow.
Bacteria can break down organic compounds at remarkable speed and help us in our waste processing and bioremediation activities. Bacteria are frequently used for cleaning up spills. They are useful in cleaning up toxic waste.
2.1. Uses of good bacteria in the human body. Gut Flora.
Gut flora consist of microorganisms that live in the digestive tracts of animals and it is the largest reservoir of human flora. It is estimated that these gut flora have around hundred times as many genes in aggregate as there are in human genome.
Though people can survive without gut flora, the microorganisms perform a host of useful functions such as fermenting unused energy substrate, training the immune system, preventing growth of harmful and pathogenic bacteria(Guamer F, Malagelada
