Wang is available to download Product Description: This new book is devoted to leading-edge research on environmental biodegradation which is the destruction of organic compounds by microorganisms.This material is available do download at niSearch.com on B. y. Wang's eBooks, Microorganisms, particularly bacteria, are responsible for the decomposition of both natural and synthetic organic compounds in nature.Environmental Biodegradation Research Focus Textbook Mineralisation results in complete conversion of a compound to its inorganic mineral constituents (for example, carbon dioxide from carbon, sulphate or sulphide from organic sulphur, nitrate or ammonium from organic nitrogen, phosphate from organophosphates, or chloride from organochlorine). Since carbon comprises the greatest mass of organic compounds, mineralisation can be considered in terms of CO2 evolution. Radioactive carbon-14 (14C) isotopes enable scientists to distinguish between mineralisation arising from contaminants and soil organic matter. However, mineralization of any compound is never 100 per cent because some of it (10-40 per cent of the total amount degraded) is incorporated into the cell mass or products that become part of the amorphous soil organic matter, commonly referred to as humus.Thus, biodegradation comprises mineralisation and conversion to innocuous products, namely biomass and humus. Primary biode...
