AbstractA Gram-staining-negative, orange-pigmented, non-motile, aerobic bacterial strain, designated GYP2O(T), was isolated from a culture of the alga Picochlorum sp., a promising feedstock for biodiesel production, which was isolated from the India Ocean. Growth was observed at temperatures from 20 to 37 degrees C, salinities from 0 to 3 % and pH from 5 to 9.Mg2+ and Ca2+ ions were required for growth. Phylogenetic analysis based on 16S rRNA gene sequencing revealed that the strain was a member of the genus Phaeodactylibacter, which belongs to the family Saprospiraceae. Strain GYP2O(T) was most closely related to Phaeodactylibacter xiamenensis KD52(T) (95.5 % sequence similarity). The major fatty acids were iso-C-15:1 G, iso-C-15:0, iso-C-17:0 3-OH and summed feature 3. The predominant respiratory quinone was menaquinone-7 (MK-7). The polar lipids of strain GYP2O(T) were found to consist of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, four unidentified glycolipids, two unidentified phospholipids and three unidentified aminolipids. According to its morphology, physiology, fatty acid composition and 16S rRNA sequence data, the novel strain most appropriately belongs to the genus Phaeodactylibacter, but can readily be distinguished from Phaeodactylibacter xiamenensis GYP2O(T). The name Phaeodactylibacter luteus sp. nov. is proposed with the type strain GYP2O(T) (=MCCC 1F01222(T)=KCTC 42180(T))
