Microorganisms mitigate a multitude of impacts that result from human
use of the natural resources of the planet. First and foremost, the essential
role of microorganisms in the treatment of waste water is critical to the well being of life on Earth. Bio-remediation, bio-mining, and microbial desulfurization of coal are other large-scale processes in which important positive environmental outcomes are achieved by directly exploiting the combined metabolic capabilities of naturally occurring communities of microorganisms. In such applications, the functioning of a particular microbial community can be influenced through the manipulation of conditions (e.g., nutrients, oxygen tension, temperature, agitation).
1) WASTE WATER TREATMENT:
Living organisms consist of about 70% water. A human being, for instance,
has to consume an average of 1.5 L/day to survive.Freshwater represents only
about 2.5% of the water on the planet and is now a scarce resourc…
