gen. nov., sp. nov., a bacterium of the family capable of aggregating potential biofuel-producing microalgae Free

Abstract

A novel bacterial strain, capable of aggregating potential biofuel-producing microalgae, was isolated from the phycosphere of an algal culture and designated HW001. The novel bacterial strain was identified on the basis of its phylogenetic, genotypic, chemotaxonomic and phenotypic characteristics in this study. Cells were aerobic, Gram-negative rods. 16S rRNA gene-based phylogenetic analysis revealed that strain HW001 is affiliated with the family in the phylum , but forms a distinct clade within this family. The DNA G+C content of strain HW001 was 55.4 mol%. The predominant cellular fatty acids were iso-C, summed feature 9 (iso-Cω9), C and summed feature 3 (Cω7/Cω6). Q-8 was the main respiratory quinone. The polar lipid profile contained phosphatidylethanolamine, an unidentified aminophospholipid and some unidentified lipids. Based on the extensive polyphasic analysis, strain HW001 represents a novel species of a new genus in the family , for which the name gen. nov., sp. nov., is proposed. The type strain of the type species is HW001 ( = CICC 10856 = KCTC 32485).
