Sinisalibacter aestuarii sp. nov., isolated from estuarine sediment of the Arakawa River

A Gram-stain-negative, rod-shaped, non-motile and strictly aerobic bacterium, which showed biofilm-forming ability on polystyrene, designated as strain B-399 T , was isolated from the estuarine sediment of the Arakawa River near Tokyo Bay. It grew at pH 6.0–8.5, at 15–35 °C and in the presence of 0–7.5 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain B-399 T was clustered in the genus Sinisalibacter and has 96.94 % sequence similarity to Sinisalibacter lacisalsi X12M-4 T , which was the only validly described species in this genus. On the basis of our genome sequencing analyses, the average nucleotide identity and digital DNA–DNA hybridization values between strains B-399 T and S. lacisalsi X12M-4 T were 79.54 and…
