Salinibacterium soli sp. nov., isolated from lakeside soil

A Gram-stain-positive, rod-shaped, non-spore-forming and non-motile bacterium, designated strain WY-16 T . Growth was observed at 20–42 °C (optimum, 30 °C), pH 6–9 (optimum, pH 7) and salinity of 0–3 % (w/v; optimum, 1 %). Phylogenetic analysis based on genome sequences indicated that WY-16 T was affiliated to the family Microbacteriaceae and most closely related to Salinibacterium xinjiangense and Salinibacterium amurskyense . The average nucleotide identity values between strain WY-16 T and S. xinjiangense and S. amurskyense were 74.7 and 72.5 %, respectively. The digital DNA–DNA hybridization values between strain WY-16 T and S. xinjiangense and S. amurskyense were 19.6 and 18.6 %, respectively. The predominant fatty acids were anteiso-C 15 : 0 , iso-C 16 : 0 and iso-C 16 : 0 10-methyl. The major menaquinones were MK-12, MK-13, MK-14 and MK-15. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, one unidentified glycolipid and one unidentified phospholipid. The cell-wall peptidoglycan contained 2,4-diaminobutyric acid as the diamino acid and ribose, rhamnose, glucose and galactose were the major cell-wall sugars. Based on phenotypic, genotypic and phylogenetic evidence, strain WY-16 T represents a novel species in the genus Salinibacterium , for which the name Salinibacterium soli sp. nov. is proposed. The type strain is WY-16 T (=GDMCC 1.4011 T =JCM 36421 T ).
