A novel lactic acid bacterium, strain TMW 2.694 T , was isolated among other lactic acid bacteria from palm wine, an alcoholic beverage produced from the sap of various palm tree species. Strain TMW 2.694 T is a Gram-positive, facultatively anaerobic, catalase-negative, non-spore-forming coccus, occurring in long chains. Phylogenetic analysis based on 16S rRNA gene sequencing positioned strain TMW 2.694 T in a distinct line of descent within the genus Leuconostoc, with the closest neighbours being Leuconostoc lactis JCM 6123 T (98.7 % sequence similarity) and Leuconostoc citreum DSM 5577 T (98.8 % sequence similarity). Comparative sequencing of the additional phylogenetic markers dnaK and recA confirmed the 16S rRNA gene tree topology. Genomic DNA-DNA similarities of strain TMW 2.694 T to L. lactis DSM 20202 T and L. citreum DSM 5577 T were 45.1 and 17.7 %, respectively. The DNA G+C content is 36.4 mol%. Thus, we propose a novel species within the genus Leuconostoc, with the name Leuconostoc palmae sp. nov. and the type strain TMW 2.694 T (5DSM 21144 T 5LMG 24510 T ).
