This study compared the genomes of W. cibaria YRK005 and W. confusa CCK931 isolated from young radish and kimchi, respectively. The genomic sizes of W. cibaria YRK005 and W. confusa CCK931 were 2.36 Mb (45%) and 2.28 Mb (44.67%), respectively. The study identified 92 and 83 CAZymes genes for W. cibaria YRK005 and W. confusa CCK931, respectively, including glycoside hydrolases and glycosyl transferases. Both strains have genes for carbohydrate esterases and carbohydrate-binding modules. The primary CAZymes involved in oligosaccharide utilization were GH1, GH2, GH30, GH13_30, GH13_31, GH42, GH43, and GH65. The study also described the production pathways for glycogen and folate in both strains.
Weissella bacteria are gram-positive, anaerobic, fermentative, and have probiotic potential. This study aimed to compare the genomes of W. cibaria YRK005 and W. confusa CCK931 isolated from young radish and kimchi, respectively. The genomic size of W. cibaria YRK005 and W. confusa CCK931 with GC content is 2.36 Mb (45%) and 2.28 Mb (44.67%), respectively. The genome study identified 92 and 83 CAZymes genes, respectively, for W. cibaria YRK005 and W. confusa CCK931, that are responsible for 26 and 27 glycoside hydrolases (GH) and 21 and 27 glycosyl transferases. Both species have one gene for carbohydrate esterases and three genes for carbohydrate-binding modules. The primary CAZymes found in both species that are involved in oligosaccharide utilization are GH1, GH2, GH30, GH13_30, GH13_31, GH42, GH43, and GH65. The study also details the production pathways for glycogen and folate. Both strains include a unique repertoire of genes, including hypothetical proteins, showing adaptability to diverse ecological niches and evolution over time.
