An overview on impact and application of microorganisms on human health, medicine and environment

Abstract

Microorganisms or microbes are microscopic organisms that exist as unicellular, multicellular, or cell clusters. Microorganisms are widespread in nature and are beneficial to life, but some can cause serious harm. They can be divided into five major types: Bacteria, Archaea, Fungi, Protozoa, and Viruses. Microbes are everywhere in the biosphere, and their presence invariably affects the environment that they are growing in. Microorganisms are beneficial in producing oxygen in environment, decomposing organic material, medicine, providing nutrients for plants, and maintaining human health, but some can be pathogenic and cause diseases in plants and humans. They perform a key role and act as main engineers in governing all ecological processes. They act as universal catalyst and provide ecological transformations. Regardless of whether they influence human health and welfare favorably or unfavorably, microorganisms are capable of profound influences on life. That is to say, it is an integral part of our lives, and therefore acquiring knowledge about it should also be essential and the main thing.
