- Abstract
- Leuconostoc is mostly found in food, plants, and dairy products. Due to their innate genomic features, such as the presence of carbohydrate-active enzymes, bacteriocins, and plasmids, Leuconostoc spp. have great biotechnological potential. In this study, four strains were isolated and identified as Leuconostoc mesen-teroides SG315 (LA), L. citreum SG255 (LB), L. lactis CCK940 (LC), and L. lactis SBC001 (LD). Comparative analysis was performed using their draft genome sequences. Differences among the four strains were analyzed using the average nucleotide identity, dot plot, and multiple alignments of conserved genomic sequences. Functional profiling revealed 2134, 1917, 1751, and 1816 open reading frames; 2023, 1823, 1655, and 1699 protein-coding genes; 60, 57, 83, and 82 RNA-coding genes; and GC content of 37.5 %, 38.8 %, 43.3 %, and 43.2 %, in LA, LB, LC, and LD, respectively. The total number of genes encoding carbohydrate-active enzymes was 76 (LA), 73 (LB), 57 (LC), and 67 (LD). These results indicate that the four strains shared a large number of genes, but their gene content is different. Furthermore, most genes with unknown functions were observed in the prophage regions of the genome. This study also eluci-dated the oligosaccharide utilization and folate biosynthesis pathways in Leuconostoc spp. Taken together, our findings provide useful information on the genomic diversity of CAZymes in the four Leuconostoc strains and suggest that these species could be used for potent exploitation.
