Culture Methods of Caproic Acid Bacteria & the Formation of Its Main Linked Products

己酸菌是窖泥中的主要功能菌之一,其含量的多少,活性的强弱,一定程度上决定着窖泥质量的优劣和窖泥活性的大小;己酸菌与浓香型白酒中的己酸、己酸乙酯的生成关系密切。就己酸菌在小体积培养和生产大体积培养过程的培养方法及结果进行了阐述,结果表明,有机培养基质的加入有利于己酸菌的生长代谢和己酸的积累;乙醇也是基质中十分重要的营养成分,乙醇的缺少,不利于己酸的积累。

Caproic acid bacteria is one of the main functional bacteria in pit mud and its content and its activity may determine pit mud quality and pit mud activity to some extent. Caproic acid bacteria is closely related to the formation ofcaproic acid and ethyl caproate in Luzhou-flavor liquor. In this paper, the culture methods and culture results of caproic acid bacteria at small-scale or large-scale were elaborated. The results suggested that the addition of organic culture mediums was beneficial to the metabolism and the growth and the accumulation of caproic acid bacteria, and ethanol was a very important component in culture medium and its absence was bad for the accumulation of caproic acid bacteria.
