Isolation and identification of Sphingomonas sp. that yields tert-octylphenol monoethoxylate under aerobic conditions.

Topsoil samples were collected from eight golf courses in Yamaguchi Prefecture, Japan, and enrichment cultures were carried out with a basal-salt medium containing 0.2% 4-tert-octylphenol polyethoxylate (OPPEO) as sole carbon source. OPPEO-degrading activity was detected in one of the samples, from which a strain of OPPEO-degrading bacterium was isolated.

Isolation of bacterial strains that produce the endocrine disruptor, octylphenol diethoxylates, in paddy fields.

Topsoil samples were collected from 36 different paddy fields in West Japan. Each soil sample was incubated with a basal salt-medium containing 0.2% OPPEO.
