Abstract

A Gram-staining-positive, coccus-shaped, non-spore-forming, facultatively anaerobic bacterium, designated AC-1, was isolated from an acidogenic fermentation bioreactor treating food wastewater. On the basis of 16S rRNA gene sequence analysis, strain AC-1 was shown to belong to the genus . The closest phylogenetic relatives were PPC9 (97.4 % 16S rRNA gene sequence similarity), CD276 (96.7 %) and ATCC BAA-640 (96.6 %). The major fatty acids were Cω9 (24.8 %) and C (19.5 %) and the G+C content of genomic DNA was 44.2 mol%, which supported the affiliation of strain AC-1 to the genus . Strain AC-1 and DSM 21480 exhibited 11 % DNA–DNA relatedness. Physiological and biochemical tests differentiated strain AC-1 from the type strains of recognized species of the genus . Therefore, strain AC-1 is considered to represent a novel species, for which the name sp. nov. is proposed. The type strain is AC-1 ( = KCTC 13418  = LMG 24798).
