Abstract

Washed cell suspensions of C. sphenoides adapted to the .gamma.-isomer of 1,2,3,4,5,6-hexachlorocyclohexane (.gamma.-HCH), metabolized .alpha.- and .gamma.-HCH but not .beta.- and .delta.-HCH. Temperature and pH optima for the metabolism of .gamma.-HCH were 40.degree. C and pH 8.0. The .gamma.-HCH-adapted suspensions also metabolized the .beta.-, .gamma.- and .delta.-isomers of 3,4,5,6-tetrachloro-2-cyclohexene, 2,3,4,5,6-pentachloro-2-cyclohexen-1-ol, .gamma.-1,2,3,4,5,6-pentachlorocyclohex-1-ene and 1,2,3,4,5-pentachlorocyclohexane. The suspensions did not metabolize a selection of chlorinated benzenes, dichlorocyclohexane and chlorocyclohexane.
