title: Weissella uvarum sp. nov., isolated from wine grapes.
abstract: Two bacterial strains (B18BM42(T) and B18NM6) were recovered during a study of bacterial diversity on wine grapes (Vitis vinifera L.) from the Nemea region in Greece. Phylogenetic analysis based on 16S rRNA gene sequences placed the two strains within the genus Weissella, and found them to be most closely related to Weissella minor NRIC 1625(T) followed by Weissella viridescens NRIC 1536(T) (99.1 and 98.9% sequence similarity, respectively). The level of DNA-DNA relatedness between strains B18NM42(T) and W. minor NRIC 1625(T) or W. viridescens NRIC 1536(T) was 31.9 and 35.0%, respectively. The two novel strains could be genetically differentiated from their closest relatives by REA-PFGE (restriction enzyme analysis-pulse field gel electrophoresis), RAPD (randomly amplified polymorphic DNA) and rep-PC R analyses (repetitive sequence-based PCR). Physiological examination showed that the novel strains can be distinguished from phylogenetically related species by their ability to grow at 42 °C and by certain carbohydrate fermentations. Based on the evidence above, the affiliation of the two strains to a novel species with the proposed name Weissella uvarum sp. nov. is suggested. The type strain is B18NM42(T) ( =DSM 28060(T) =NCCB 100484(T)).
