Complete genome sequence of Latilactobacillus curvatus CACC879 and its functional probiotic properties.

Latilactobacillus curvatus CACC879 originated from swine feces in Korea, and its probiotic properties have been analyzed. The complete genome of strain CACC879 contained one chromosome 1,398,247 bp in length and three circular plasmids, namely, pCACC879-1 (591,981 bp), pCACC879-2 (14,542 base pairs [bp]), and pCACC879-3 (45,393 bp). The complete genome encodes a total of 2,077 genes, including 25 rRNA genes and 90 tRNA genes. In addition, probiotic stability- genes acid/bile related to salts tolerance, the biosynthesis of cobalamin (vitamin B12), riboflavin (vitamin B2), and CRISPR/Cas9 were found in the whole genomes. Remarkably, L. curvatus CACC879 contained the antioxidant-related (peroxiredoxin) and bacteriocin-related genes ( lysM and blpA ). Overall, these results demonstrate that L. curvatus CACC879 is a functional probiotic candidate for animal industry applications.
