Abstract

A bacterial strain designated SBNa008 was isolated from a Philippine soil sample. It exhibited the general characteristics associated with myxobacteria, such as swarming of Gram-negative vegetative rod cells, fruiting body and myxospore formation and predatory behaviour in lysing micro-organisms. The novel strain was characterized as mesophilic, chemoheterotrophic and aerobic. The major fatty acids were Cω6,9,12,15 all (arachidonic acid), iso-C, C 2-OH and iso-C dimethylacetal. Interestingly, SBNa008 contained diverse fatty acids belonging to the commercially valuable polyunsaturated omega-6 and omega-3 families, and a highly conjugated dihydroxylated C steroid. The G+C content of the genomic DNA was 67.3 mol%. The 16S rRNA gene sequence revealed 95–96 % similarity to sequences derived from clones of uncultured bacteria and 94–95 % similarity to cultured members of the suborder . Phylogenetic analysis revealed that strain SBNa008 formed a novel lineage in the suborder . Based on a polyphasic taxonomic characterization, we propose that strain SBNa008 represents a novel genus and species, gen. nov., sp. nov. The type strain of is SBNa008 ( = DSM 24000 = NCCB 100349).
