[The primary stages of alpha-methylstyrene degradation by a culture of Pseudomonas aeruginosa 8].
The transient products have been characterized of alpha-methylstyrene (AMS) degradation by P. aeruginosa st. 8 which utilizes AMS in high concentrations (2-10 g/l) as the only source of carbon and energy. The existence of two pathway of AMS catabolism has been demonstrated. The minor pathway is connected with accumulation of nonmetabolized products of an isopropenyl fragment. The main pathway leads through formation of hydroxylation products with subsequent meta-cleavage of aromatic ring. A possible participation of wide-specific meta-pyrocatechase in AMS catabolism has been discussed.
