| Sumario: | <i>Lactiplantibacillus plantarum</i> is a diverse species that includes nomadic strains isolated from a variety of environmental niches. Several <i>L. plantarum</i> strains are being incorporated in fermented foodstuffs as starter cultures, while some of them have also been characterized as probiotics. In this study, we present the draft genome sequence of <i>L. plantarum</i> L125, a potential probiotic strain presenting biotechnological interest, originally isolated from a traditional fermented meat product. Phylogenetic and comparative genomic analysis with other potential probiotic <i>L. plantarum</i> strains were performed to determine its evolutionary relationships. Furthermore, we located genes involved in the probiotic phenotype by whole genome annotation. Indeed, genes coding for proteins mediating host–microbe interactions and bile salt, heat and cold stress tolerance were identified. Concerning the potential health-promoting attributes of the novel strain, we determined that <i>L. plantarum</i> L125 carries an incomplete plantaricin gene cluster, in agreement with previous in vitro findings, where no bacteriocin-like activity was detected. Moreover, we showed that cell-free culture supernatant (CFCS) of <i>L. plantarum</i> L125 exerts anti-proliferative, anti-clonogenic and anti-migration activity against the human colon adenocarcinoma cell line, HT-29. Conclusively, <i>L. plantarum</i> L125 presents desirable probiotic traits. Future studies will elucidate further its biological and health-related properties. |
