ECONOMIC IMPORTANCE OF BACTERIA

Most importance bacteria are harmless to humans, and many bacteria are essential or useful to the existence of plant and animal life. Only a small fractions of bacteria causes disease; most bacteria attack organic matter only after it is dead. Were it not for bacteria that decomposed animals and plants. These material would accumulate almost indefinitely. So many bacteria are useful for us, if no bacteria in this world, the world will full just in short time.

Bacteria also enrich the soil in various ways. The so-called nitrogen fixing bacteria take nitrogen gas fro the atmosphere and convert it to a form (nitrate) that green plants use for growth. Bacteria also create fertilizer by breaking down compost heaps made of soil and dead plat matter.

Bacteria are important industrially in the production of cheese, yogurt, buttermilk, vinegar, and sauerkraut; in the preparations of antibiotic such as streptomycin, which is extracted from soil bacteria; in the tanning of leather and hides and the curing of tobacco; and in the sewage disposal plants to render organic wastes harmless. Cattle, sheep, and goats live on the grass; yet without bacteria they would not be able to digest the tough fibers of plant cellulose.

Improperly processed foods are subject to spoilage by bacteria. Poisonous toxins are sometimes produced by such spoiling bacteria as staphylococci, Streptococci, and Salmonella. They cause severe illness human eating affected food. Clostridium botolinum, growing in canned or smoked foods that have been improperly processed, produces a toxin that causes Botulism, frequenly fatal disease.

Hi every body, off course bacteria useful and also dangerous to human and to other creature. Its depend of the kind of bacteria, like bacteria E coli that exist on our stomach is very useful to make our meal rest become spoil. If there is no E coli on our stomach than we will feces out as what we eat.

Bacteria is waaaaaaay vary important to us eventhough it is sort of harmful to the humans....yet in bio technology and genetic engineering bacteria plays a vital role regarding various process eg fermentation..making of cheese yogurt etc...in the formation of insulin and antibiotics and lalalala...they are very small organisms which reproduce by both sexual and asexual means..binary fission spore formation are asexual modes of reproduction..=D

INDUSTRIAL IMPORTANCE:- The products obtained as a result of bacterial activities cannot be chemically prepared. Bacteria are involved in following industries.
DAIRY PRODUCTS:- The manufacture of almost all milk products (Butter, cheese, curd or ghee) is based on bacterial activities. Common bacteria found in milk are Streptococcus lactis, Lactobacillus lactis, Aerobacter aerogenes, Escherichia coli & species of Bacillus, Clostridium, Proteus, Sarcina, Pseudomona
