The document discusses the functional properties of Bacillus coagulans, a thermostable lactic acid-forming probiotic bacteria. B. coagulans spores can survive the harsh conditions of the stomach and intestinal tract. It can settle in the digestive tract and produce lactic acid and other substances that inhibit pathogenic bacteria. Studies also suggest B. coagulans may have immune-modulating effects and help regulate blood sugar and lipid levels. Due to its heat resistance and health benefits, B. coagulans is seen as a promising probiotic for supporting gut and overall health.
