Lactobacillus reuteri

The species Lactobacillus reuteri was recognized and recorded in scientific classifications of lactic acid bacteria, as early as the turn of the 20th century. At this time it was mistakenly grouped as a member of Lactobacillus fermentum. In the 1960s, further work by German microbiologist Gerhard Reuter could distinguish Lactobacillus reuteri from Lactobacillus fermentum. Reuter reclassified the species as “Lactobacillus fermentum biotype II”.
