Biostimulation involves the modification of the environment to stimulate existing bacteria capable of bioremediation. This can be done by addition of various forms of rate limiting nutrients and electron acceptors, such as phosphorus, nitrogen, oxygen, or carbonBiotechnology is a broad area of biology, involving the use of living systems and organisms to develop or make products. Depending on the tools and applications, it often overlaps with related scientific fields Biotechnology means any technological application that uses biological systems or living organisms to make or modify products or processes for specific use. ... Bio- Technology is concerned with variety of subjects including Biochemistry, Genetics, Microbiology, Chemistry and Engineering.The goal of biotechnology is to produce drugs by using living organisms such as bacterial cells, yeast, mammalian cells, etc., that are placed in culture to produce substances with pharmacological activity, such as monoclonal antibodies for the treatment of tumors.
