Pentachlorophenol (PCP) 
An isolate of Cephaloascus fragrans adapted to concentrations of PCP. 
Some degradation of PCP was observed with T. virgatum. No metabolites were 
identified (318). 
Other studies indicated that disappearance of PCP in soils was more 
rapid in watered than in unwatered soils and that decomposition proceeded 
more rapidly in soils of high organic matter than in those of low organic 
content. Leaching did not appear to be important in the disappearance of 
PCP: (1530). 
Studies showed that PCP was bound to muscle protein. Binding was 
markedly increased by decreasing pH from 9 to 7 and by addition of KCl, 
MgCl5, and (CH,) ,, NC1l. Acetylation of actomysin greatly decreased the 
amount of bound PCP. This suggested that binding occurred on amino groups 
(146).
