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 C20 : 4ω6,9,12,15 all cis (arachidonic acid), iso-C15 : 0, C17 : 1 2-OH and iso-C15 : 0 dimethylacetal. Interestingly, SBNa008T contained diverse fatty acids belonging to the commercially valuable polyunsaturated omega-6 and omega-3 families, and a highly conjugated dihydroxylated C28 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 Sorangiineae . Phylogenetic analysis revealed that strain SBNa008T formed a novel lineage in the suborder Sorangiineae . Based on a polyphasic taxonomic characterization, we propose that strain SBNa008T represents a novel genus and species, Minicystis rosea gen. nov., sp. nov. The type strain of Minicystis rosea is SBNa008T ( = DSM 24000T = NCCB 100349T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.068270-0
