Lactic Acid Bacterium - an overview | ScienceDirect Topics
Lactic acid bacteria are a class of Gram-positive, non-spore-forming, non-reactive but gas-tolerant microorganisms. They are usually characterized by their ability to produce lactic acid. Lactic acid bacteria, as an indispensable fermentation bacterium, are considered a kind of probiotic.
