Project description:We report here the complete genome sequence of Lactobacillus johnsonii strain Byun-jo-01, which was isolated from the murine gastrointestinal tract. The genome was determined using both PacBio and Illumina sequencing. L. johnsonii strain Byun-jo-01 contains a single circular chromosome of 1,959,519 bp, and its GC content is 34.7%.
Project description:Whole genome DNA microarray designed for the probiotic L. johnsonii strain NCC533 was used for comparative genomic hybridization (CGH) of L. johnsonii ATCC 33200T, L. johnsonii BL261, L. gasseri ATCC 33323T and L. iatae BL263 (CECT 7394T). In these experiments, the fluorescence ratio distributions obtained with L. iatae and L. gasseri showed characteristic inter-species profiles. The percentage of conserved L. johnsonii NCC533 genes was about 83% in the L. johnsonii strains comparisons and decreased to 51% and 47% for L. iatae and L. gasseri, respectively. These results confirmed the separate status of L. iatae from L. johnsonii at the level of species, and also that it is closer to L. johnsonii than L. gasseri.
