Aurantisolimonas haloimpatiens gen. nov., sp. nov., a bacterium isolated from soil

Abstract

A Gram-stain negative, strictly aerobic and non-motile bacterium, designated strain BN130233T, was isolated from a soil sample collected from Gyeongsangbuk-do, Republic of Korea. Colonies were orange in colour, with wet and smooth surfaces. Phylogenetic analyses based on the 16S rRNA gene sequences resulted in strain BN130233T forming a cluster with members of the family Chitinophagaceae Kampfer et al. 2011, while sharing the highest sequence identity of 91.2% with Chitinophaga niastensis JS16-4T. Good growth was observed at 20？28 C, pH 7.0 and in the absence of NaCl. The major fatty acids were summed feature 3 (C16: 1ω6c and/or C16: 1ω7c), iso-C15: 1 G, iso-C15: 0 and iso-C17: 0 3-OH. The respiratory quinone was MK-7. Major polar lipids contained phosphatidylethanolamine, an unidentified phospholipid, three unidentified aminolipids and eight unidentified lipids. The genomic DNA G+C content was 40.6 mol%. Phenotypic and chemotaxonomic characteristics together with 16S rRNA gene sequence analyses showed that strain BN130233T was distinct from its close phylogenetic relatives in the family ChitinophagaceaeKampfer et al. 2011. The strain is, therefore, proposed as a representative of a new genus and new species with the name Aurantisolimonas haloimpatiens. The type strain of Aurantisolimonas haloimpatiens is BN130233T (=CCTCC AB 2017051T=KCTC 42642T).
