Sembiring, J. Winter] Summary: A pure culture presumably of an Acetobacterium sp. from a waste water pond, strain B10, was able to grow with several methoxylated aromatic compounds by demethylation (or demethoxylation) to the corresponding hydroxilated substances. Acetate was formed from the eliminated methyl or methoxy groups and from CO2. Demethylation of 3-methoxybenzoate occurred simultaneously with glucose or lactate fermentation if induced, methanol-grown cells of strain B10 were used as an inoculum. If 2-vanillin or 2,3-dimethoxybenzaldehyde were supplied as the only carbon sources, these substances were first oxidized to the corresponding benzoic acid derivatives and subsequently demethylated. In mixed cultures of strain B10 and Desulfosarcina variabilis or Desulfosarcina strain DSU3 the 3-hydroxybenzoate formed by strain B10 from 3-methoxybenzoate was completely degraded to acetate and presumably CO2 by the sulphate reducers. Acetate could be oxidized to CO2 upon extended incubation. The complete degradation of 3-methoxybenzoate to CO2 by co-cultures of strain B10 and Desulfosarcina strains seemed to proceed via a commensalistic, rather than via a syntrophic interaction of the participating organisms.
