Complete genome sequence of bacteriocin-producing Ligilactobacillus salivarius B4311 isolated from fecal samples of broiler chicken with anti-listeria activity

<italic>Ligilactobacillus </italic>is a genus of Gram-positive lactobacilli commonly found in the intestinal tracts of vertebrates. It has been granted a Qualified Presumption of Safety (QPS) status from the European Food Safety Authority (EFSA). One specific strain, <italic>Ligilactobacillus salivarius </italic>B4311, was isolated from fecal samples of broiler chickens from a farm associated with Chung-Ang University (Anseong, Korea). This strain was observed to have inhibitory effects against <italic>Listeria monocytogenes</italic>. In this paper, we present the complete genome sequence of <italic>Lig. salivarius </italic>B4311. The whole genome of strain<italic> </italic>B4311 comprises 2,071,255 bp assembled into 3 contigs representing a chromosome, <italic>repA</italic>-type megaplasmid, and small plasmid. The genome contains 1,963 protein-coding sequences, 22 rRNA genes, and 78 tRNA genes, with a guanine + cytosine (GC) content of 33.1%. The megaplasmid of strain B4311 was found to contain the bacteriocin gene cluster for salivaricin P, a two-peptide bacteriocin belonging to class IIb.
