Salinimicrobium sp. 3283s Genome sequencing. Salinimicrobium sp. 3283s

Salinimicrobium sp. 3283s is an aerobic, golden-yellow pigment-producing, Flavobacteriaceae bacterium isolated from the sediments of South China Sea. In this study, we present the complete genome sequence of strain 3283s, which only have a single circular chromosome comprising 3,702,683 nucleotides with 41.41% G + C content and no circular plasmid. In total, 3257 protein coding genes, 45 tRNA genes, 9 rRNA genes, and 13 sRNA genes were obtained. In terms of the function of gene annotation, strain 3283s was more different from S. oceani J15B91, which was isolated from the South China Sea at a similar depth, and more similar to S. profundisediminis MT39, which was closer in phylogenetic taxonomic status, suggesting that strain 3283s possesses a stronger potential to adapt to the deep-sea environment. In addition, we found a large number of genes in strain 3283s that can promote better adaptation of the bacteria to the low oxygen and high pressure environment of the deep sea, such as genes encoding antioxidant pigments, genes encoding cytochromes with enhanced affinity for oxygen, proteins for adaptation to high pressure, and genes encoding TBDRs in the absence of flagella.
