A Micrococcus sp., isolated by enrichment culture, grew on 4-chlorobiphenyl at 2 g/l as sole carbon source and produced 4-chlorobenzoic acid in the culture medium as a dead-end metabolite. The organism degraded 4-chlorobiphenyl by 2,3-dihydroxylation followed by meta-ring cleavage to yield 4-chlorobenzoate and carbon fragments for cell growth.
A bacterium capable of utilizing biphenyl as the sole source of carbon was isolated from soil and identified as a Micrococcus species. The organism also utilized 4-chlorobiphenyl and several other aromatic compounds as growth substrates. 2,3-Dihydroxybiphenyl and benzoic acid were identified as intermediates by physico-chemical methods. The bacterium(More)
