Novel biotransformations of 4-chlorobiphenyl by a Pseudomonas sp.
A bacterium, tentatively identified as a representative of the genus Pseudomonas (strain MB86), was isolated from soil contaminated by wood-preservation chemicals by using 4-chlorobenzoate as an enrichment substrate. The pseudomonad was able to grow on 4-chlorobenzoic acid and 4-chlorobiphenyl as sole carbon and energy sources. Spent culture medium from 4-chlorobiphenyl-grown cells contained 4-chlorobenzoic acid, 4'-chloroacetophenone, 2-hydroxy,2-[4'-chlorophenyl] ethane, and 2-oxo,2-[4'-chlorophenyl] ethanol as metabolites. 4'-Chloroacetophenone was produced in large amounts, possibly as a dead-end metabolite.
