Abstract

A taxonomic study was conducted on two Gram-reaction-positive, catalase-negative, irregular short-rod-shaped or coccoid lactic acid bacteria, designated strains SG25 and SG23, that were isolated from grains of fermented Japanese rice ( L. subsp. ). A phylogenetic analysis based on 16S rRNA gene sequence data clearly showed that the strains belonged to the genus and were most closely related to LMG 20113 (with a sequence similarity of 96.9 % for each novel strain). The peptidoglycan of each strain contained the amino acids glutamic acid, lysine, serine and alanine in a molar ratio of 1.0 : 1.2 : 0.5 : 3.0, respectively. On the basis of the unusual phenotypic characteristics of the novel strains and the low levels of DNA–DNA relatedness recorded between each novel strain and JCM 12536, strains SG25 and SG23 represent a single novel species in the genus , for which the name sp. nov. is proposed. The type strain is SG25 ( = JCM 18191  = DSM 25784).
