Bio degradation

Bio degradations the process of decay or breakdown of materials that occurs when the small small microorganisms use an organic substances as a source of carbon and other energy. For example, sewage flows to the waste water where many of the organic compounds are broken down . These bio degradation processes are essential to recycle wastes so that the elements in them can be used again.Those materials, which are hard to break down, may enter the environment as contaminants.

Bio degradation is a microbial process which occurs when all of the nutrients and physical conditions are suitable for their growth. Temperature is a very important variable; keeping a substance frozen can prevent bio degradation.
