摘要
啤酒的腐败细菌有革兰氏阳性菌(乳酸菌、片球菌、Mk.ristinae等)和革兰氏阴性菌(Pectinatus、巨型球菌Z、r.affinosivorans等)。啤酒中的酒花具有抑制腐败菌的作用,主要物质为异α-酸;酒花能对微生物体内的酶起药物钝化、改变目的底物、抑制药物流入等作用。对啤酒腐败菌的检测方法有聚合酶链式反应(PCR)、伏安型生物传感器检测鉴定微生物细胞、自动微生物检测系统(AMS)、改良MRS培养基检测啤酒中乳酸菌和ATP法。(孙悟)
The beer spoilage bacteria coveres Gram-positive bacteria such as lactobacillus and M.kristinae etc. and Gram-negative bacteria such as Pectinatus, macrococci and Z.roffinosivorans etc. The hops in beer with its main components as iso-α-acid could inhibit the activity of beer spoilage bacteria. Besides, the hops had the functions of inactivating enzymes in microbial body, changing goal objects, and inhibiting the inflow of medicine etc. The detection methods of beer spoilage bacteria covere polymerase chain reaction （PCR）, automatic microbial detection system （AMS） and ATP method etc. （Tran. by YUE Yang）
