Sulfitobacter sediminis sp. nov., a novel halophilic bacterium isolated from tidal flat sediment

A corrigendum of this article has been published full details can be found at 10.1099/ijsem.0.006740 A novel bacterial strain, MJW-29 T , was isolated from tidal flat sediment in Gochang, Republic of Korea. The isolate is Gram-stain-negative, facultatively anaerobic, gliding motile and short rods. The strain MJW-29 T is oxidase and catalase positive. Growth is observed at 25–40 °C (optimum, 30 °C) and pH 5–9 (optimum, pH 7.0) in the presence of 0–9% (w/v) NaCl (optimum, 5.0% NaCl). The 16S rRNA gene sequence identity analysis showed that the strain MJW-29 T is closely associated with Tateyamaria armeniaca KMU-156 T (97.2%), Sulfitobacter alexandrii AM1-D1 T (97.2%), Sulfitobacter sediminilitoris JBTF-M27 T (97.0%) and Thalassovita litoraria KU5D5 T (96.9%) from the family Roseobacteraceae . The major respiratory quinone was Q-10. The major polar lipids were phosphatidylglycerol, phosphatidylcholine, phospholipid and an unidentified lipid. The major cellular fatty acids of type strain MJW-29 T were C 18:1 ω 7c/C 18:1 ω 6c (64.5%). The genome length of the type strain MJW-29 T is 4.9 Mbp (DNA G+C content, 62.1 mol%). It has 4638 coding genes and 43 tRNAs. The average aa identity values; average nt identity values; and biochemical, phylogenetic and physiological characteristics support the genotypic and phenotypic differentiation of strain MJW-29 T from other members of the genus Sulfitobacter . The strain MJW-29 T represents a novel species of the genus Sulfitobacter in the family Roseobacteraceae , for which the name Sulfitobacter sediminis sp. nov. is proposed. The type strain is MJW-29 T (=KCTC 8634 T =KEMB 20189 T =JCM 37145 T ).
