...aten, the S. mutans population explodes, excreting lactic acid as it digests sugar. The acid makes life difficult for other helpful bacteria and demineralizes tooth enamel, causing decay. According to the U.S. Centers for Disease Control and Prevention, 95 percent of adult Americans suffer from tooth decay....HIV prevention hope: Yogurt bugs that make antiviral drugs

...ell's survival depends on it to convert glucose to lactic acid through glycolysis even in the presence of ample oxygen. Disruption of the switch by a drug may cause cancer cells to pollute themselves with toxic oxygen molecules and undergo apoptosis or cell death. The new finding, made by Hopkins graduate s...Lactic acid not athlete's poison, but an energy source - if you know how to use it
