己酸菌的选育与应用研究

Breeding Selection of Caproic Acid Bacteria and Its Application

己酸菌是一种能够在培养液中积累己酸的功能菌。以优质大曲发酵池的窖泥为材料,采用厌氧培养分离方法筛选出己酸菌;进行耐热、耐酒精、耐pH及厌氧培养试验。可将选育出的己酸菌用于人工窖泥、窖池泥养护、翻沙材料及灌窖工艺中。(孙悟)

Capro ic acid bacteria,a kind of functional bacteria that could accumulate caproic acid in culture fluid,was prepared by anaerobic culture and separation of pit mud o f quality Daqu fermentation pits.And quality caproic acid bacteria was obtained through tests of temperature resistant ,alcohol resistant ,pH resistant ,and anaerobic culture.The selected caproic acid bacteria could then be used in the maintenance of artificial pit mud and the operation of sand cast technique and pit irrigation technique.(Tran.by YUE Yang)
