Abstract
The degradation of l-alanine by three strains of sulfate-reducing bacteria that can grow with l-alanine as an energy source was investigated. In Desulfotomaculum ruminis and most likely also in two marine Desulfovibrio strains alanine is converted to pyruvate via an NAD-dependent alanine dehydrogenase. D. ruminis contained high activities of soluble NADH and NADPH dehydrogenases. In the marine strains the activities were much lower and the NADH dehydrogenase was partly associated with the membrane fraction.
