More...Ensuring the viability and efficacy of probiotic microorganisms during manufacturing and gastrointestinal transit remains challenging, particularly for sensitive strains like lactic acid bacteria and bifidobacteria. This has led to increased interest in spore-forming bacteria, such as Heyndrickxia coagulans (formerly Bacillus coagulans), which can endure environmental stresses through their endospore forms. This study presents a comprehensive analysis of the probiotic potential of strain LMG S-24828, originally isolated from healthy human feces. The genomic analysis confirmed the strain's taxonomic placement within the species H. coagulans and revealed no extrachromosomal plasmid DNA, suggesting genetic stability. Safety assessments demonstrated that LMG S-24828 does not produce D-lactate, deconjugate bile salts, or exhibit hemolytic activity, and it lacks transmissible antibiotic resistances. Phenotypic tests showed the strain's metabolic versatility, including its ability to hydrolyze complex carbohydrates and adhere to intestinal epithelial cells. Moreover, LMG S-24828 exhibited robust survival and germination during in vitro and in vivo gastrointestinal simulations, with evidence of significant spore germination in the human gut. These findings suggest that H. coagulans LMG S-24828 possesses several advantageous traits for probiotic applications, warranting further clinical evaluation to confirm its health benefits.
