A Gram-staining-negative, strictly aerobic, non-motile, yellow-pigmented bacterium, designated strain M091(T), was isolated from seawater at Damupo beach in Pohang, Republic of Korea, and investigated using a polyphasic taxonomic approach. The novel strain grew optimally at 25 degrees C, pH 7.0-8.0, and in the presence of 3% (w/v) NaCl. In a phylogenetic analysis based on 16S rRNA gene sequences, strain M091(T) formed a lineage within the family Flavobacteriaceae that was distinct from the most closely related genera of Flaviramulus (95.1% sequence similarity), Algibacter (94.9-93.9 %), Mariniflexile (94.8-94.2 %), Winogradskyella (94.8-93.2 %), Lacinutrix (94.7-93.8%) and Tamlana (94.7-92.9%). The polar lipid profile of the novel strain comprised phosphatidylethanolamine, two unidentified aminolipids, one unidentified phospholipid and seven unidentified lipids. The predominant cellular fatty acids were iso-C-15:0 (20.5%), iso-C-17:0 3-OH (15.4%), iso-C-15:0 3-OH (12.4 %), C-15:0 (10.9%) and iso-C-15:1 G (9.9 %). The genomic DNA G+C content of strain M091(T) was 34.4 mol% and the major respiratory quinone was MK-6. Based on phenotypic and genotypic data, strain M091(T) represents a new genus and novel species in the family Flavobacteriaceae, for which the name Postechiella marina gen. nov., sp. nov. is proposed. The type strain of the type species is M091(T) (=KCTC 23537(T)=JCM 17630(T)). X 1 1 10 9 scie scopus
