Abstract:
Streptococcus hyointestinalis B19 was isolated from chicken feces collected from local farm in Anseong, Korea. S. hyointestinalis B19 was shown to produce bacteriocin-like compounds exhibiting inhibitory activities against several pathogens including strains of Clostridium perfringens and Listeria monocytogenes. The whole genome of S. hyointestinalis B19 strain was sequenced using PacBio RS II platform. The genome comprised four contigs with a size of 2,217,061 bp. The DNA G + C content was found to be 42.95 mol%. Annotation results revealed 2,266 coding sequences (CDSs), 18 rRNAs, and 61 tRNA genes. Based on genome analysis, we found that the strain B19 possessed various genes associated with bacteriocin synthesis, modification, and transport.
