Abstract

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.

摘要

从受木材防腐化学品污染的土壤中,以4 - 氯苯甲酸作为富集底物,分离出一种细菌,初步鉴定为假单胞菌属的代表菌株(菌株MB86)。该假单胞菌能够以4 - 氯苯甲酸和4 - 氯联苯作为唯一的碳源和能源生长。以4 - 氯联苯培养的细胞的废弃培养基中含有4 - 氯苯甲酸、4'-氯苯乙酮、2 - 羟基 - 2 - [4'-氯苯基]乙烷和2 - 氧代 - 2 - [4'-氯苯基]乙醇作为代谢产物。大量产生了4'-氯苯乙酮,可能是作为一种终产物代谢物。
