Studies on Microbial Degradation of Toxic Phosphorus Esters. Part 1. Detoxification of O, O-Dimethyl-O-(2-carbomethoxy-1-methylvinyl) Phosphate by Soil Bacteria


Book Description

In an attempt to find a new method for detoxifying cholinesterase-inhibiting, organophosphorus compounds, studies were undertaken to isolate bacteria capable of degrading O, O-dimethyl-O-(2-carbomethoxy-1-methylvinyl) phosphate (Phosdrin). Degradation of the insecticide was determined by gas chromatography, while decreased toxicity was confirmed by measuring cholinesterase activity with a recording pH stat. Of the thirty cultures screened, two showed 80-90% degradation of the original 20 ppm Phosdrin in 10 days, with a corresponding decrease in toxicity. One of the cultures was isolated from soil collected on Eglin Air Force Base, Florida, and the other as a laboratory contaminant. The bacteria were identified as two different strains of Bacillus megaterium. (Author).

Enzymes in Action Green Solutions for Chemical Problems


Book Description

Enzymes in Action is a timely survey of a modern development in organic chemistry. It is clear that bioreagents demand that organic chemists think in a different way. If they do so, they will open up new avenues of exciting, new chemistry that will permit problems to be solved in an elegant way. The first section covers the concepts necessary to understand enzymes in molecular operations. The second section covers heteroatom enzyme chemistry, with considerable attention being given to the use of enzymes in the detoxification of chemical warfare agents and their application in environmental problems. The final section highlights the strategic use of enzymes in organic chemistry. It is clear that the term `green chemistry' is appropriate, since enzyme mediated processes occur under mild, environmentally benign conditions, and enzymes enable chemists to perform new chemical operations that would otherwise be difficult to achieve at all.







Theoretical and Methodological Basis of Continuous Culture of Microorganisms


Book Description

Theoretical and Methodological Basis of Continuous Culture of Microorganisms deals with the continuous cultivation of microorganisms.
