Studies on sulfite reduction by Desulfovibrio vulgaris.

Dissimilatory reduction of sulfites by Desulfovibrio vulgaris was investigated. Medium with alpha-glycerophosphate as a source of organic carbon and phosphorus was applied. It was found that sulfite at the concentration up to 1M Na2SO3 is not toxic for D. vulgaris and acts efficiently as an electron acceptor. Basing on the presented results, a general mechanism of microbiological transformation of sulfites is proposed.
