Abstract

A lactic acid bacterium, strain CCTCC M 2011381, isolated from the brine of the traditional Chinese snack, stinky tofu, was studied to determine its taxonomic position. It was a Gram-stain-positive, non-motile, facultatively anaerobic rod-shaped bacterium that did not exhibit catalase activity. The DNA G+C content of the strain was 44.1 % and its peptidoglycan was characterized by the presence of -diaminopimelic acid. Levels of 16S rRNA gene sequence similarity between strain CCTCC M 2011381 and the most closely related species JCM 17472, JCM 14109 and JCM 12183 were 96.5, 96.4 and 96.4 %, respectively. Combined with data from high-resolution genomic markers , and , strain CCTCC M 2011381 was classified as representing a novel species. The strain could also be distinguished from other related species of the genus by its physiological and biochemical characteristics. Based on the phylogenetic, physiological and biochemical data, it is proposed that the new isolate can be classified as representing a novel species of the genus , for which the name sp. nov. (type strain CCTCC M 2011381 = S1L19 = JCM 18524) is proposed.
