Important Bacteria:
Most of the bacteria
are harmful but some bacteria are useful. So here we review functions of these
useful bacteria and see how they help in healing process:
Industrial Bacteria:
These bacteria help
in ripening and curing of curdling of milk, fermentation of sugar into alcohol,
conversion of hides into leather, tobacco leaves, ripening of cheese, retting
(softening) of fibers etc. These bacteria play an important role in industries
economic production including Health Food industry, Wine Industry, Dairy &
Meat Industries and many more.
Alimentary canal bacteria:
They help herbivores
in the digestion of cellulose by producing an enzyme cellulose. Few are present
in human beings and produce vitamins.
Agricultural bacteria:
They decompose dead
animals and plants and convert them into organic compounds and then into simple
form such as phosphates, sulphates etc for utilization to make green plants
again. Nitrifying bacteria change proteins into the dead bodies of both animals
and plants in the nitrates; therefore these nitrates are utilized and absorbed
by green plants. Soil bacteria increase the fertility and take chemical &
physical changes in the soil.
Medicinal bacteria:
The important and valuable antibiotics drugs are gained by bacteria, like
subtilin and thyrothycin. Clostridium produce a vitamin called riboflavin.
