Research progress of Bacillus in Baijiu brewing

Chinese Baijiu is unique among the world alcoholic drinks because of its unique production technology and liquor body style, in which multi- strains fermentation is the main technological feature different from other distilled liquors. As an important microorganism in the brewing process of Baijiu, Bacillus has an extremely important influence on the flavor and quality of liquor. The species, diversity, functional characteristics, and the application of functional Bacillus in Baijiu brewing process were summarized, and the future research direction of Bacillus was prospected, aiming to provide theoretical reference for the application of Bacillus in Baijiu production, which was of great significance for Baijiu quality improvement production.
