Two strains of sulfate-reducing bacteria (J.5.4.2-L4.2.8^T and J.3.6.1-H7) were isolated from a pyrite-forming enrichment culture and were compared phylogenetically and physiologically to the closest related type strain Desulfovibrio sulfodismutans DSM 3696^T. The isolated strains were vibrio-shaped, motile rods that stained Gram-negative. Growth occurred from 15 to 37 °C and within a pH range of 6.5–8.5. Both strains used sulfate, thiosulfate, sulfite, and dimethyl sulfoxide (DMSO) as electron acceptor when grown with lactate. Lactate was incompletely oxidized to acetate. Formate and H₂ were used as electron donor in the presence of acetate. Dismutation of thiosulfate and pyrosulfite was observed. The two new isolates differed from D. sulfodismutans by the utilization of DMSO as electron acceptor, 82% genome-wide average nucleotide identity (ANI) and 32% digital DNA-DNA hybridization (dDDH), thus representing a novel species. The type strain of the type species Desulfovibrio desulfuricans Essex6^T revealed merely 88% 16S rRNA gene identity and 49% genome-wide average amino acid identity (AAI) to the new isolates as well as to D. sulfodismutans. Furthermore, the dominance of menaquinone MK-7 over MK-6 and the dominance of ai-C_15:0 fatty acids were observed not only in the two new isolated strains but also in D. sulfodismutans. Therefore, the definition of a new genus is indicated for which the name Desulfolutivibrio is proposed. We propose for strains J.5.4.2-L4.2.8^T and J.3.6.1-H7 the name Desulfolutivibrio sulfoxidireducens gen. nov. sp. nov. with strain J.5.4.2-L4.2.8^T defined as type strain. In addition, we propose the reclassification of Desulfovibrio sulfodismutans as Desulfolutivibrio sulfodismutans comb. nov.

从形成黄铁矿的富集培养物中分离出两种还原硫酸盐的细菌菌株（J.5.4.2-L4.2.8 ^T和J.3.6.1-H7），并在系统发育和生理上与最接近的相关类型菌株Desulfovibrio sulfodismutans进行了比较。 DSM 3696 ^Ť。分离的菌株是弧形的能动的杆，其染色为革兰氏阴性。生长温度为15至37°C，pH范围为6.5–8.5。与乳酸菌一起生长时，两种菌株均使用硫酸盐，硫代硫酸盐，亚硫酸盐和二甲基亚砜（DMSO）作为电子受体。乳酸未完全氧化为乙酸盐。甲酸酯和H ₂在乙酸盐的存在下用作电子给体。观察到硫代硫酸盐和焦亚硫酸盐的歧化。这两个新隔离株与通过使用DMSO作为电子受体，D。sulfodismutans，82％的全基因组平均核苷酸同一性（ANI）和32％的数字DNA-DNA杂交（dDDH），从而代表了一个新物种。Desulfovibrio desulfuricans Essex6 ^T型种的菌株仅对新分离株和D. sulfodismutans揭示了88％的16S rRNA基因同一性和49％的全基因组平均氨基酸同一性。此外，不仅在两个新分离的菌株中，而且在D. sulfodismutans中也观察到了甲萘醌MK-7优于MK-6以及ai -C _15：0脂肪酸的优势。因此，指明了新属的定义，其名称为提出了去硫磺活性。我们为菌株J.5.4.2-L4.2.8 ^T和J.3.6.1-H7提议名称Desulfolutivibrio sulfoxidireducens gen。十一月 sp。十一月 应变J.5.4.2-L4.2.8 ^T定义为类型应变。另外，我们建议将脱硫弧菌硫二歧菌重新分类为脱硫弧菌硫二齿菌梳。十一月
