Abstract
Lactiplantibacillus sp. LM14-2, isolated from Thai-fermented mussel (Hoi-dong), showed attractive probiotic properties. This strain was identified as Lactiplantibacillus plantarum based on its phenotypic, chemotaxonomic, and genetic characteristics including whole-genome sequencing (WGS). The draft genome sequence was analyzed and annotated for the molecular mechanisms involved in the safety assessment, the adaptation and adhesion of L. plantarum LM14-2 to the gastrointestinal tract (GIT), and the beneficial genes involved in bacteria-host interactions. The L. plantarum LM14-2 exhibited bile salt hydrolase (BSH) activity, assimilated cholesterol at 86.07 ± 5.03%, stimulated the secretion of interleukin-12, interferon-gamma, and human beta defensin-2, and induced nitric oxide production. In addition, L. plantarum LM14-2 showed excellent gastrointestinal tolerance and adhesion ability to Caco-2 cells. Furthermore, the in silico analysis showed that L. plantarum LM14-2 was a non-human pathogen and did not contain antibiotic resistance genes or plasmids. L. plantarum LM14-2 also contained potential genes associated with various probiotic characteristics and health-promoting effects. Consequently, this study suggested that L. plantarum LM14-2 could be considered safe, with potential probiotic properties and health-promoting impacts, which could facilitate its probiotic application.
