A novel lactic acid bacterium, strain TMW 2.694T, was isolated among other lactic acid bacteria from palm wine, an alcoholic beverage produced from the sap of various palm tree species. Strain TMW 2.694T 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 2.694T in a distinct line of descent within the genus Leuconostoc, with the closest neighbours being Leuconostoc lactis JCM 6123T (98.7 % sequence similarity) and Leuconostoc citreum DSM 5577T (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 2.694T to L. lactis DSM 20202T and L. citreum DSM 5577T 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 2.694T (=DSM 21144T =LMG 24510T).

The GenBank/EMBL/DDBJ accession numbers for the 16S rRNA, recA and dnaK gene sequences of Leuconostoc palmae TMW 2.694T are AM940225–AM940227, respectively; those for the recA and dnaK gene sequences of Leuconostoc holzapfelii LMG 23990T are AM940228 and AM940229, respectively; that for the dnaK gene sequence of Leuconostoc lactis JCM 6123T is AM940230.

Supplementary figures showing maximum-parsimony and maximum-likelihood 16S rRNA gene trees are available with the online version of this paper.
