Microbial reactions of nonsteroidal compounds have been described and tabulated in a recent book on the subject. (1) The use of microorganisms as chemical reagents has been discussed in two books (2,3) and one book chapter; (4) and as tools in the modification of drugs (4) or as models of mammalian metabolism in other by: 4. Microbial degradation of halogenated organic compounds in anoxic estuarine and marine sediments is widely observed (Table 1) and generally proceeds first via reductive l studies have shown that alternate electron acceptors, in particular sulfate, impede the enrichment of dehalogenating populations, or that interspecific competition for electron donors inhibits anaerobic.

Wiley-Liss, New York Google Scholar. Halogenated organic compounds can be subject to transformation by microorganisms under both anoxic and oxic conditions. Higher halogenated substances, such as tetrachlorethene (PCE) or hexachlorobenzene (HCB), are usually transformed under anoxic conditions via reductive dehalogenation, but persist under oxic conditions.

Transformations of 1- and 2-carbon halogenated aliphatic organic compounds under methanogenic conditions. Appl Environ Microbiol. Apr; 45 (4)– Preliminary dehalogenation of highly halogenated compounds by the reduced metal to generate less halogenated byproducts those are susceptible for microbial degradation. Therefore, the integration of zerovalent metals with biodegradation promotes the dehalogenation efficiency of each type of remediation methods. Prior to the s, knowledge of biological transformations of highly halogenated aliphatic compounds was limited, except in mammalian organisms where enzymatic transformations occurred to rid the body of ingested harmful chemicals. Purified versatile peroxidase (VP) from the white rot fungus Bjerkandera adusta UAMH was used to study the transformation of several pesticides, including some as highly halogenated as the wood preservative pentachlorophenol (PCP). From the 13 pesticides assayed, dichlorophen, bromoxynil and PCP were transformed by VP in the presence and in the absence of manganese(II).
