Sulfitobacter sabulilitoris sp. nov., isolated from marine sand

A Gram-stain-negative, aerobic, non-motile and ovoid or rod-shaped bacterial strain, HSMS-29 T , was isolated from a marine sand sample collected from the Yellow Sea, Republic of Korea. The neighbour-joining phylogenetic tree of 16S rRNA gene sequences showed that strain HSMS-29 T fell within the clade comprising the type strains of Sulfitobacter species. Strain HSMS-29 T exhibited 16S rRNA gene sequence similarities of 97.2-98.4 % to the type strains of Sulfitobacter mediterraneus , Sulfitobacter porphyrae , Sulfitobacter marinus , Sulfitobacter pontiacus , Sulfitobacter litoralis , Sulfitobacter brevis , Sulfitobacter noctilucicola and Sulfitobacter dubius and 96.3-96.9 % to the type strains of the other Sulfitobacter species. The genomic ANI values of strain HSMS-29 T with the type strains of S. mediterraneus , S. marinus , S. pontiacus , S. litoralis , S. brevis , S. noctilucicola and S. dubius were 72.66-74.99 %. The DNA-DNA relatedness value between strain HSMS-29 T and the type strain of S. porphyrae was 17 %. Strain HSMS-29 T contained Q-10 as the predominant ubiquinone and C 18 : 1 ω 7 c as the major fatty acid. The major polar lipids of strain HSMS-29 T were phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, one unidentified aminolipid and one unidentified lipid. The DNA G+C content of strain HSMS-29 T was 65.0 mol% (HPLC) or 64.4 % (genome analysis). Distinguished phenotypic properties, along with the phylogenetic and genetic distinctiveness, revealed that strain HSMS-29 T is separated from recognized Sulfitobacter species. On the basis of the data presented here, strain HSMS-29 T is considered to represent a novel species of the genus Sulfitobacter , for which the name Sulfitobactersabulilitoris sp. nov. is proposed. The type strain is HSMS-29 T (=KACC 19870 T =NBRC 113549 T ).
