【摘要】 选择酒明串珠菌31DH和SD-1作为研究菌株,在ATB培养基中研究了SO2对苹果酸-乳酸细菌菌株的影响以及SO2与酒精和低pH之间的协同作用。结果表明,SO2的抑菌效果受pH值影响,pH值越低抑制作用越强烈;结合态SO2与酒精存在协同作用,但当浓度>40mg/L时,结合态SO2浓度的增加对酒精抑制作用的增强并不明显。更多还原

【Abstract】 Oenococcus31DH and SD-1were selected as research microbial strains.The effects of SO 2 on malolactic bacteria in ATB culture medium and the conspiracy of SO 2 and alcohol or low pH value were studied.The research results indicated that the bacte-riostasis effects of SO 2 were influenced by pH value and lower pH value had stronger inhibitory effects,the combinative SO 2 had con-spiracy with alcohol,as SO 2 concentration above40mg /L,the increase of SO 2 concentration had unconspicuous inhibitory effects on alcohol.(Tran.by YUE Yang)更多还原
