Animal experiments show that BL21 can effectively reduce blood sugar levels in diabetic mice, improve the antioxidant capacity of the livers, repair intestinal barrier damage, reduce inflammatory reactions, and improve intestinal flora disorders in diabetic mice. At the same time, the combined use of BL21 with Lactiplantibacillus plantarum Lp90, Lactiplantibacillus plantarum CW006, Lactiplantibacillus plantarum N13 and Pediococcus acidilactis CCFM7902 can effectively regulate the body's blood sugar metabolism and alleviate the symptoms of hyperglycemia.

C. elegans model experiments have proven that Lp90 can effectively reduce fat accumulation and has potential efficacy in preventing obesity. At the same time, Lp90 can scavenge free radicals, has good superoxide dismutase activity, and has good antioxidant capacity.

It has good tolerance to gastric juice and bile salts, and also has proteolytic activity. It can metabolize and produce angiotensin-converting enzyme inhibitory peptide to achieve anti-hypertensive effects.

It can inhibit the growth of enteroinvasive Escherichia coli (EIEC), inhibit the adhesion and invasion of EIEC to intestinal epithelial cells, and improve the intestinal flora.

It has a strong inhibitory effect on the growth of Listeria monocytogenes, can inhibit the growth of common pathogenic bacteria, increase the number of beneficial bacteria, and regulate intestinal flora.
