Salinarimonas soli sp. nov., isolated from soil.

Abstract

A light pink coloured bacterium, designated strain BN140002T, was isolated from a soil sample collected in Goesan-gun, Chungcheongbuk-do, Republic of Korea. Cells of strain BN140002T were Gram-stain-negative, aerobic, motile and rod-shaped. Phylogenetic analysis based on 16S rRNA gene sequences showed 94.7, 94.7, 93.9, 93.3, 93.4 and 93.0% similarities to Salinarimonas rosea KCTC 22346T, Salinarimonas ramus DSM 22962T, Saliniramus fredricksonii HL-109T, Microvirga soli R491T, Chelatococcus caeni EBR-4-1T and Chelatococcus composti PC-2T, respectively. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine and phosphatidylethanolamine. The major cellular fatty acids were summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c) and summed feature 1 (C12 : 0 aldehyde and/or unknown 10.98) and the predominant ubiquinone was Q-10. The genomic DNA G+C content of strain BN140002T was 70.1 mol%. The genomic orthoANI values between strain BN140002T and Salinarimonas rosea KCTC 22346T and Salinarimonas ramus DSM 22962T were 75.0 and 74.8 %, respectively. Strain BN140002T had a class I-C type CRISPR-Cas system (CRISPR-associated helicase Cas3, CRISPR-associated protein Cas8c, CRISPR-associated protein Cas7, CRISPR-associated RecB family exonuclease Cas4, CRISPR-associated protein 1, 2). Based on phenotypic, chemotaxonomic and phylogenetic data, strain BN140002T should be assigned as a novel species of the genus Salinarimonas, for which the name Salinarimonas soli sp. nov. is proposed. The type strain is BN140002T (=KCTC 42643T=CCTCC AB 2017173T).
