“…Although extensive work has been done on biphenyl (Dodge et al, 1979;Wiseman et al, 1975;Cox and Golbeck, 1985), no study was concerned with microbial hydroxylation of biphenyl oxide. Studies suggested that Cunninghamella echinulata effectively parahydroxylated some synthetic substrates (Pasutto et al, 1987). The possible toxicity of biphenyl oxide toward previously selected fungal strains (Chapelle et al, 1986) has been checked and the bioconversion of biphenyl oxide investigated under various culture conditions.…”
