Various aromatic compounds can be broken down anaerobically a model oganism, Rhodopseudomonas palustris. These results show that R. palustris is one of the most versatile of the anaerobic bacteria described to date with respect to aromatic degradation. The probable metabolic routes taken were assessed by analyzing growth patterns and the accumulation of partial degradation products by wild type strains and by a mutant blocked in anaerobic degradation of benzoate and 4-hydroxybenzoate. The main conclusion reached from these studies is that R. palustris uses two major routes for aromatic degradation; one that flows through benzoate and one that flows through 4-hydroxybenzoate. Thus there appear to be two major pathways that mediate the fission of aromatic rings under anaerobic conditions. 7 refs., 2 figs.
