Aquabacter spiritensis, gen. nov., sp. nov. an aerobic, gas-vacuolate aquatic bacterium
A gram-negative, rod-shaped, gas-vacuolate, aerobic, heterotrophic bacterium was isolated from Spirit Lake, Washington. It was further characterized by phase-contrast and electron microscopy and phenotypic tests. The isolate does not utilize carbohydrates. Deoxyribonucleic acid-ribosomal ribonucleic acid (rRNA) hybridizations showed that this bacterium is a member of rRNA superfamily IV where it occupies a separate position on the Azorhizobium caulinodans rRNA sub-branch which, is part of an rRNA cluster containing also the Beijerinckia, the Bradyrhizobium japonicum and the Rhodopseudomonas palustris sub-branches. Its relationship to other gas-vacuolated genera within rRNA superfamily IV is discussed. A new genus Aquabacter with one species Aquabacter spiritensis is proposed. The type strain is strain SPL-1 (=ATCC 43981=LMG 8611). © 1991 Springer-Verlag.
