Abstract. The isolated soil bacteria Acinetobacter strain BEM2 is able to utilize some xenobiotic aromatic compounds as a carbon source. In this study the metabolism of 4-hydroxybenzoate (4-HBA) by strain BEM2 was characterized. Degradation involved a meta-cleavage pathway yielding 3,4-dihydroxybenzoate (3,4-DHBA) as an intermediate and CO2 as the principal product from the C atoms in the aromatic ring. 4-HBA uptake was studied, and the kinetic parameters were determined. The uptake was shown to be directly coupled to ATP hydrolysis and its synthesis, according to the Mitchell chemiosmotic hypothesis.
