Streptococcus lactate is a peptide compound composed of many amino acids, which can be absorbed by the human body as a nutrient. Streptococcus lactate is widely used as a food preservative in the food industry because it can inhibit most gram-positive bacteria and has a strong inhibitory effect on the spores of Bacillus. After eating in the body's physiological pH conditions and under the action of alpha-chymotrypsin hydrolysis into amino acids, soon will not change the human intestinal normal flora and produce as other antimicrobial resistance problems, not other antibiotics and cross-resistance, is a highly efficient, non-toxic, safe, no side effects of natural food preservatives.
Nisin is a natural anti-microbial agent used as a preservative in heat-processed and low-pH foods. Its anti-microbial activity is used against a wide range of gram-positive bacteria and their spores, which cause food spoilage. It especially inhibits heat-resistant bacilli, such as B.Stearothermophilus, C. Butyricum, and L. monocytogenes. Nisin alone is not effective against gram-negative bacteria or yeasts and molds. Research has shown that Nisin in combination with chelating agents such as EDTA or nonionic surfactants such as Polysorbate 20, shows potent bactericidal activity against gram-negative organisms.
