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

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 degrees C in the presence of 0-3% (w/v) NaCl (pH 7.0). The major fatty acids of strain FJxs(T) were iso-C-15:0, iso-C-15:0, 30H. summed feature 3, C-16:0 iso-C-15:1 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-1-3-6(T), 94.36% with Sinomicrobium pectinilyticum 5DNS001(T), and 93.52% with Sinomicrobium oceani SCSIO 03483(T). 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 2019251(T)=KCTC 72740(T)).

Automated summary

A new species of the genus Sinomicrobium, named Sinomicrobium weinanense sp. nov., was isolated from saline-alkali soil in China. This Gram-negative, facultative anaerobic, non-motile, rod-shaped strain grew optimally at 37-40 degrees C, pH 7.0, and in the presence of 0-3% (w/v) NaCl. Phylogenetic and genotypic analyses showed that it exhibited highest sequence identity with Sinomicrobium soli N-1-3-6(T), Sinomicrobium pectinilyticum 5DNS001(T), and Sinomicrobium oceani SCSIO 03483(T).
