Strain FOL01T was isolated from traditionally fermented Korean jogae jeotgal (fermented clams). Phylogenetic sequence analysis of the 16S rRNA gene from FOL01T revealed that it is closely related to Weissella thailandensis FS61-1T and Weissella paramesenteroides ATCC 33313T with 99.39 % and 98.50 % 16S rRNA gene sequence similarities, respectively. API and VITEK analyses showed that strain FOL01T could be separated from its nearest phylogenetic relatives with respect to carbohydrate fermentation and antibiotic resistance. Subsequent amplified rRNA gene restriction analysis of 16S rRNA genes and HaeIII-restriction enzyme profiling of genomic DNAs revealed different band patterns. In addition, DNA-DNA hybridization of genomic DNAs showed 63.9 % relatedness. Analysis of the composition of cellular fatty acids confirmed that strain FOL01T differs from its close relatives and supports the proposal to assign this organism to a novel species of the genus Weissella. Based on these results, strain FOL01T could be classified as a novel species of the genus Weissella, for which the name Weissella jogaejeotgali sp. nov. is proposed. The type strain is FOL01T ( = KCCM 43128T = JCM 30589T).
