gen. nov., sp. nov., a new member of the family isolated from soil.

A Gram-stain-negative, non-motile, moderately halophilic and facultatively anaerobic bacterium, designated YR4-1, was isolated from a saline-alkali and sorghum-planting soil sample collected in Dongying, Shandong Province, PR China. Growth occurred at 28-45 °C with the presence of 4.0-20.0 % (w/v) NaCl and pH 6.0-9.0. Phylogenetic analysis based on the 16S rRNA gene sequences revealed that YR4-1 shared the highest similarity of 92.1-92.4 % with the valid published species of . The isolate formed a separate clade at the genus level in recently described family . The draft genome of strain YR4-1 is 3.83 Mbp long with 44.0 mol% G+C content. The strain possesses several genes involved in the osmotic stress response mechanism and diverse metabolic pathways, probably for the living in saline environment. This may lead to a better understanding of the underrepresented lineage. The major menaquinone was MK-7. The main polar lipid profile was composed of diphosphatidylglycerol, phosphatidylglycerol, phosphoglycolipids, aminophosphoglycolipid, one glycolipid, and four unidentified lipids. The predominant cellular fatty acids were iso-C (35.7 %) and anteiso-C (33.5 %). On the basis of its phenotypic, chemotaxonomic and phylogenetic features, strain YR4-1 represents a novel species of a new genus, for which the name gen. nov., sp. nov. is proposed. The type strain is YR4-1 (=CGMCC 1.17777=KCTC 72795).
