Abstract: | The cytochrome P450, identified by the characteristic 450 nm spectral peak of its carbon monoxide complex, was detected in the hepatopancreatic microsomes ofMytilus galloprovincialis, collected from Ponteau (Bay of Fos, France) in 1982 and 1983. When mussels were exposed to a variety of petroleum hydrocarbons, the cytochrome P450 content increased. It is shown that aromatic hydrocarbons are more effective than alkanes in inducing a high level of cytochrome P450. The possible use of this haemoprotein in hydrocarbon pollutant detection is discussed. |
