Genome analysis revealed a repertoire of oligosaccharide utilizing CAZymes in CCK931 and YRK005.

Unlabelled: bacteria are gram-positive, anaerobic, fermentative, and have probiotic potential. This study aimed to compare the genomes of YRK005 and CCK931 isolated from young radish and kimchi, respectively. The genomic size of YRK005 and 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 YRK005 and 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.
