Sporeformers as Human Probiotics: Bacillus, Sporolactobacillus, and Brevibacillus



The value of exogenously supplied live bacteria for the maintenance of health in humans has been recognized both scientifically in the published literature and commercially in the availability of probiotic products.

This article reviews the characterization, efficacy, and safety of sporeformers used as probiotics.
