Ernst Moro founded Lactobacillus acidophilus leading to the field of probiotics, is attributed to Élie Metchnikoff around 1907. 

Élie Metchnikoff, a pioneering Russian scientist, is considered the discoverer of probiotics and linked their health benefits to the consumption of containing Lactobacillus strains, particularly Lactobacillus acidophilus, which he believed could promote longevity by replacing harmful bacteria with beneficial ones in the gut. He theorized that consuming products containing L. acidophilus, could alter the gut flora to enhance health and delay aging. 

The most famous strain, Lactobacillus rhamnosus GG (LGG), was discovered by Sherwood Gorbach and Barry Goldin in 1983 from a healthy human's intestinal tract. Gorbach is a professor in the departments of Community Health and Family Medicine and Molecular Biology and Microbiology at the School of Medicine and a professor at the Friedman School of Nutrition Science and Policy.

Barry Goldin originally isolated a potential probiotic strain from the healthy adult human in 1985. Owing to its stability in acid and bile medium, good growth characteristics and excellent adhesive property, the strain was patented and named “Lactobacillus rhamnosus GG.” His work has centered on the role of bacteria-derived vitamin K in gut health, inflammation, and gut microbiota composition.

German microbiologist

Gerhard Reuter, a German microbiologist, first isolated and described Lactobacillus reuteri in 1962. He discovered it was native to the human microbiome. Gerhard Reuter is an academic researcher from Free University of Berlin. The author has contributed to research in topics: Lactobacillus & Bifidobacterium.

Bergey's Manual of Systematic Bacteriology is a comprehensive, authoritative, and widely used reference work for classifying and describing prokaryotic microorganisms, providing detailed information on their taxonomy, physiology, ecology, and evolution, and is now succeeded by the continuously updated online resource, Bergey's Manual of Systematics of Archaea and Bacteria (BMSAB).

American Maize (AMAIO) was a Chicago-based company, initially the Western Glucose Company, founded in 1906 and completed in 1907 by the Royal Baking Powder Company.
