Abstract:
A Gram-staining-negative, orange-pigmented, non-motile, aerobic bacterial strain, designated GYP20 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 °C, salinities from 0 to 3 % and pH from 5 to 9.Mg 2+ and Ca 2+ 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 GYP20 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 GYP20 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 GYP20 T . The name Phaeodactylibacter luteus sp. nov. is proposed with the type strain GYP20 T ( = MCCC 1F01222 T = KCTC 42180 T ).
