Activity of phase I and phase II detoxication enzymes in Antarctic and Arctic macroalgae

摘要

Presented data demonstrate the existence of various phase I and phase II detoxication enzymes in nine species of Antarctic and Arctic macroalgae cultivated under laboratory conditions. The different enzyme activities were widely distributed in the tested Chlorophyta. Phaeophyta and Rhodophyta. Concerning the cytochrome P-450 monooxygenase system, it was possible to determine several activities for fatty acid substrates such as lauric acid, palmitic acid and stearic acid and furthermore for 3-chlorobiphenyl, a xenobiotic substrate. The conversion of the 3-chlorobiphenyl to a monohydroxymonochlorobiphenyl was established using gas chrmatography-mass spectrometry (GC-MS).
