What is the economic importance of microbes?

Answer 1

microorganisms play different roles in the economy indirectly by rendering services to mankind in the fields of medical,industrial,ecological/environmental,food,and agriculture.
some microorganisms like algae serves as delicacy in the oriental countries and are found to be great sources of nutrition,certain fermented foods like cheese,curd,yogurt,paneer,tofu,kimchi,natto,fermented fishes,idly,dosas,bambooshoots etc are obtained through the activities of microorganisms.
therefore they are found to be very important factors in the field of fermentation food and food products.
beer from barley,whiskey from wheat,rum and other fermented drinks are also obtained through the fermentative property of microorganisms.
following the discovery of penicillin from the fungus penicillium notatum,many other antibiotics have been manufactured,and also in collaboration with biotechnology,high quality yields of crops,disease resistant crops and biopesticides are manufactured from certain microorganisms.
in the field of environment,organisms help in the breakdown of pollutants esp in water and soil helping in the remediation process which is called bioremediation,they also help in treatment of sewage,sludge etc. ethanol has been produced from maize corn which is expected to replace petroeum fuel thereby being eco-frieldly and bringing down pollution. there are many other aplications of organisms,however these are just a few of them

Answer 2

Microorganisms are economically important because they help in the production of many foods. Microorganisms such as bacteria fertilize soil; therefore, without microorganisms we would not be able to grow crops.

Answer 3

Microorganisms come under the category of decomposers. The microorganisms, comprising bacteria and fungi, break-down the dead remains and waste products of organisms. These microorganisms are the decomposers as they break-down the complex organic substances into simple inorganic substances that go into the soil and are used up once more by the plants.

Answer 4

They are the important and cheap source to carry out fermentation (bacteria, yeast). They degrade the waste and some toxins efficiently (biodegradation). They can fix nitrogen in plants and so on.
