Sinomicrobium weinanense sp. nov., a halophilic bacterium isolated from saline-alkali soil

Abstract

A Gram-stain-negative, facultative anaerobic, non-motile, rod-shaped strain was isolated from saline-alkali soil collected in PR China, and it was designated as strain FJxs T . Its optimal growth was observed at 37–40 °C in the presence of 0–3 % (w/v) NaCl (pH 7.0). The major fatty acids of strain FJxs T were iso-C15 : 0, iso-C17 : 0 3OH, summed feature 3, C16 : 0 and iso-C15 : 1 G. The predominant respiratory quinone was menaquinone 6. The DNA G+C content of the strain was 45.18 mol%. Whole genome and 16S rRNA gene sequence analyses indicated that strain FJxs T exhibited 94.78 % sequence identity (the maximum) with Sinomicrobium soli N-1-3-6T, 94.36 % with Sinomicrobium pectinilyticum 5DNS001T, and 93.52 % with Sinomicrobium oceani SCSIO 03483T. Analyses of genotypic, phenotypic, phylogenetic and chemotaxonomic characteristics indicated that strain FJxs T represented a novel species of the genus Sinomicrobium . This novel species was named Sinomicrobium weinanense sp. nov. with its type strain as FJxs T (=CCTCC AB 2019251T=KCTC 72740T).
