Complete genome sequence of Pediococcus acidilactici CACC 537 isolated from canine

Abstract

Pedi coccus acidilactici CACC 537 was isolated from canine feces and reported to have pro -biotic properties. We aimed to characterize the potential probiotic properties of this strain by functional genomic analysis. Complete genome sequencing of P. acidilactici CACC 537 was performed using a PacBio RSII and Illumina platform, and contained one circular chromo-some (2.0 Mb) with a 42% G + C content. The sequences were annotation revealed 1,897 protein-coding sequences, 15 rRNAs, and 56 tRNAs. It was determined that P. acidilactici CACC 537 genome carries genes known to be involved in the immune system, defense mechanisms, restriction-modification (R-M), and the CRISPR system. CACC 537 was shown to be beneficial in preventing pathogen infection during the fermentation process, help host immunity, and maintain intestinal health. These results provide for a comprehensive under-standing of P. acidilactici and the development of industrial probiotic feed additives that can help improve host immunity and intestinal health.
