Abstract

A mesophilic, acetate-oxidizing, sulfur-reducing bacterium, strain NZ27, was isolated from anoxic mud from a freshwater sulfur spring. The cells were ovoid, motile, and gram negative. In addition to acetate, the strain oxidized pyruvate, succinate, and fumarate. Sulfur flower could be replaced by polysulfide as an electron acceptor. Ferric nitrilotriacetic acid was reduced in the presence of pyruvate; however, this reduction did not sustain growth. These phenotypic characteristics suggested that strain NZ27 is affiliated with the genus . A phylogenetic analysis based on the results of comparative 16S ribosomal DNA sequencing confirmed that strain NZ27 belongs to the cluster in the recently proposed family “” in the delta subgroup of the . In addition, the results of DNA-DNA hybridization studies confirmed that strain NZ27 represents a novel species. , a name tentatively used in previous publications, is the name proposed for strain NZ27 in this paper.
