RESUMEN

Sulphate-reducing bacteria Desulfomicrobium sp. CrR3 and Desulfotomaculum. sp. are able to use fumarate as electron donor and acceptor. When they use fumarate as an electron acceptor succinate accumulates in the medium. If fumarate serves as electron donor, minor amounts of citrate, isocitrate and acetate are detected except succinate. In the case of simultaneous introduction of fumarate, SO4(2-) and Cr2O7(2-), the last inhibits usage of fumarate and SO4(2-).
