Scientists Discover Natural Antibiotic That Could Protect Foods From Deadly Microbes

Researchers in Minnesota have patented a newly discovered, naturally occurring peptide produced by a harmless bacteria that could be added to food as a potent weapon against deadly foodborne bacteria such as salmonella, E. coli and listeria. According to scientists, the lantibiotic they discovered is the first natural preservative that destroys so-called “gram-negative” bacteria, typically the harmful kind. The substance could protect many foods – meats, processed cheeses, egg and dairy products, canned foods, seafood, salad dressing, fermented beverages, etc. – from a broad range of disease-causing microbes. Lantibiotics are easy to digest, nontoxic, and nonallergenic. And dangerous bacteria have a hard time developing a resistance to them.
