Sulfitobacter sediminis gen. nov., sp. nov., a novel halophilic bacterium isolated from tidal flat sediment.
A novel bacterial strain, MJW-29T, 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-29T 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-29T is closely associated with Tateyamaria armeniaca KMU-156T (97.2%), Sulfitobacter alexandrii AM1-D1T (97.2%), Sulfitobacter sediminilitoris JBTF-M27T (97.0%) and Thalassovita litoraria KU5D5T (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-29T were C18:1ω7c/C18:1ω6c (64.5%). The genome length of the type strain MJW-29T 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-29T from other members of the genus Sulfitobacter. The strain MJW-29T 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-29T (=KCTC 8634T=KEMB 20189T=JCM 37145T).
期刊介绍：
Published by the Microbiology Society and owned by the International Committee on Systematics of Prokaryotes (ICSP), a committee of the Bacteriology and Applied Microbiology Division of the International Union of Microbiological Societies, International Journal of Systematic and Evolutionary Microbiology is the leading forum for the publication of novel microbial taxa and the ICSP’s official journal of record for prokaryotic names.
The journal welcomes high-quality research on all aspects of microbial evolution, phylogenetics and systematics, encouraging submissions on all prokaryotes, yeasts, microfungi, protozoa and microalgae across the full breadth of systematics including:
Identification, characterisation and culture preservation
Microbial evolution and biodiversity
Molecular environmental work with strong taxonomic or evolutionary content
Nomenclature
Taxonomy and phylogenetics.
