Bacillus Coagulans

Organism Overview

Bacillus coagulans is a spore-forming, L+ lactic-acid-producing microorganism. Due to the unique amount of lactic acid B. coagulans produces, it was originally classified taxonomically as Lactobacillus sporogenes. Yet, because of the protective spore it forms around itself like other Bacillus species, it was later re-classified.

Because of this unique history, B. coagulans is thought of as a “best-of-both-worlds” organism: it has the added protection of it’s spore with the desired benefits of good lactic acid production.
