Abstract

Deoxyribonucleic acid hybridization indicated that species of the genera and are phylogenetically diverse. The 10 strains examined in this study fall into four phylogenetically defined groups. The first group (, and ) is physiologically the most diverse, containing mesophiles and thermophiles and containing marine and nonmarine organisms. The second group (, and contains very small mesophilic coccoid organisms from anaerobic digestors. The third group contains a single species, , which was isolated from a solfataric mud pool, and the fourth group contains the type species, , which is a marine organism. Based on the high deoxyribonucleic acid sequence similarity between and , we propose to transfer to the genus , naming it comb. nov. The type strain is strain MSt (= DSM 3027 = OGC 21). The species in the other three major groups are placed in the genus , although the lack of phylogenetic relatedness indicates that some of these organisms should be separated from into new genera. However, we propose that cataloging or sequencing of ribosomal ribonucleic acid from these species must be completed before new genera are designated.
