✦ Synopsis

The reduction of elemental or sulfane sulfur to hydrogen sulfide by eubacteria was investigated. Spirillum 5175 had the most active sulfur oxidoreductase. It could be cultivated with fumarate (F), elemental sulfur (S) or nitrate (N) as electron acceptor. Maximum activity was found for Spirillum 5175s but activity was also present in Spirillum 5175F and Spirillum 5175N, i.e. the sulfur oxidoreductase is a constitutive enzyme. It was localized in the membrane, and no activity was found in the cytoplasm in contrast to
