Abstract
The ε-caprolactum-utilizing bacteria were searched. Among 40 authentic strains stored in the IAM Culture Collection, only one strain, Pseudomonas ovalis JAM 1002, was found to utilize ε-caprolactam as a sole sourse of carbon and nitrogen. From the polluted water lines of the Nylon 6 manufacturing plant (Nagoya Plant, Toyo Rayon Co., Ltd., Nagoya) 11 strains of this nature were also isolated and identified. Various characteristics of these bacteria are described.
