Both 4,4'-dichlorobiphenyl (4,4'-DCB) and 3-methylcholanthrene (3-MC) caused a substantial increase of phenacetin-induced hepatic glutathione (GSH) depletion, whereas phenobarbital (PB) had no effect, suggesting that 4,4'-DCB possesses cytochrome P-448 inducing activity. The O-deethylation of phenacetin by liver microsomes from control and

Surfactant and organic solvents have individually been shown useful in assisting the solubilization of hydrophobic organics out of contaminated soil and promoting UV-induced photodecay at a succeeding treatment process. A newly proposed process is to use the mixtures of surfactant

Acinetobacter sp. strain 4CB1 was isolated from a polychlorobiphenyl-contaminated soil sample by using 4-chlorobenzoate as a sole source of carbon and energy. Resting cells of Acinetobacter sp. strain 4CB1 hydrolytically dehalogenated 4-chlorobenzoate under aerobic and anaerobic conditions, but 4-hydroxybenzoate accumulated

The white rot fungus Phanerochaete chrysosporium has demonstrated abilities to degrade many xenobiotic chemicals. In this study, the degradation of three model polychlorinated biphenyl (PCB) congeners (4,4'-dichlorobiphenyl [DCB], 3,3',4,4'-tetrachlorobiphenyl, and 2,2',4,4',5,5'-hexachlorobiphenyl) by P. chrysosporium in liquid culture was examined.
