Degradation of phenanthrene and anthracene by cell suspensions of Mycobacterium sp. strain PYR-1
Article Abstract:
Researchers describe a novel metabolic pathway in Mycobacterium sp. strain PYR-1 for degrading phenanthrene and anthracene. This might be due to different dioxygenases or to a greater substrate variability on the part of the same dioxygenase.

Regio- and stereoselective metabolism of 7,12-dimethylbenz[a]anthracene by Mycobacterium vanbaalenii PYR-1
Article Abstract:
Research examines the biodegradation of the carcinogenic polycyclic aromatic hydrocarbon 7,12-dimethylbenz[a]anthracene by Mycobacterium vanbaalenii PYR-1. The biodegradation process involves dioxygenation and monooxygenation reactions and proceeds in a highly regio- and stereoselective manner.

Initial oxidation products in the metabolism of pyrene, anthracene, fluorene, and dibenzothiophene by the white rot fungus Pleurotus ostreatus
Article Abstract:
The white rot fungus Pleurotus ostreatus metabolizes pyrene and anthracene to form trans dihydrodiols. Pyrene trans-4,5-dihydrodiol is mainly the R,R enantiomeric form while anthracene trans 1,2-dihydrodiol is mainly the S,S form. Fluorene is metabolized to 9-fluorenol and 9-fluorenone, and dibenzothiophene to its sulfoxide and sulfone. The metabolism products suggest the involvement of a cytochrome P-450 monooxygenase in the reaction. The results of the study indicate that the metabolism of polycyclic aromatic hydrocarbons by P. ostreatus is similar to that by nonligninolytic fungi.
