Nisin A(Cat No.:R063869) is a naturally occurring antimicrobial peptide produced by the bacterium Lactococcus lactis. It belongs to the class of bacteriocins known as lantibiotics, which are characterized by their antimicrobial activity against a wide range of Gram-positive bacteria, including foodborne pathogens like Listeria monocytogenes. Nisin A works by disrupting bacterial cell walls, leading to cell death. Due to its safety and effectiveness, it is widely used as a food preservative, particularly in dairy products, canned foods, and beverages, where it helps extend shelf life by preventing bacterial spoilage. Nisin A is also being studied for its potential applications in medical and pharmaceutical fields, particularly in combating antibiotic-resistant bacteria.
