Lactobacillus brevis

Lactobacillus brevis is a species of lactic acid bacteria (LAB) commonly found in fermented foods, plant materials, and the gastrointestinal tracts of animals. It is a facultative heterofermentative bacterium, meaning it can produce both lactic acid and other metabolites such as acetic acid and ethanol from carbohydrate fermentation, depending on environmental conditions.

In equine nutrition, Lactobacillus brevis may be included in probiotic formulations aimed at supporting gut microbial balance. As a probiotic, it contributes to maintaining a stable microbial ecosystem in the hindgut by competing with pathogenic bacteria, producing beneficial metabolites, and supporting the fermentation of dietary fiber.
