 Lactobacillus reuteri

At the turn of the 20th century, "L. reuteri" was recorded in scientific classifications of lactic acid bacteria, though at this time it was mistakenly grouped as a member of "Lactobacillus fermentum".In the 1960s, further work by microbiologist Gerhard Reuter – for whom the species eventually was named – began to distinguish "L. reuteri" from "L. fermentum".
