title: Weissella kimchii sp. nov., a novel lactic acid bacterium from kimchi.
abstract: A gram-positive, catalase-negative, non-sporulating, facultatively anaerobic, short rod-shaped bacterium, with cells measuring 0.3-0.5 x 1-2 microm and designated strain CHJ3T, was isolated from partially fermented kimchi, a traditional Korean fermented vegetable food. The strain produced CO2 gas, D-lactate from glucose and dextran from sucrose and hydrolysed aesculin and arginine. It also fermented N-acetylglucosamine, amygdalin, arbutin, cellobiose, D-fructose, galactose, beta-gentiobiose, gluconate, D-glucose, maltose, D-mannose, salicin, sucrose and D-xylose. The G+C content of the DNA was 48.2 mol%. Phylogenetic analysis of 16S rRNA showed that strain CHJ3T is a member of the genus Weissella. The nearest phylogenetic relative of strain CHJ3T was Weissella confusa, with 16S rRNA similarity of 98.3%. However, strain CHJ3T could be differentiated from W. confusa on the basis of some phenotypic characteristics, analysis of whole-cell protein patterns and DNA-DNA hybridization data. These data suggest that strain CHJ3T be classified in the genus Weissella as a novel species, Weissella kimchii sp. nov. The type strain is CHJ3T (= KCCM 41287T = DSM 14295T = KCTC 3746T).
