Lactobacillus rhamnosus was originally considered to be a subspecies of L. casei, but new genetic research found it to be a species of its own. L. rhamnosus inhibits growth of most harmful bacteria in the gut. It is used as a natural preservative in yogurt and other dairy products to extend the shelf life. Some studies have been done on its in vivo effects.
