柚皮提取物的抑菌作用研究

Studies on Anti-Microbial Activities of Shaddock Peel Extract

摘要: 研究了机皮提取物（ＳＰＥ）对细菌、酵母、霉菌的抑制作用。实验结果证明：柚皮提取物对苏云金芽胞杆菌、卵黄色八桑球菌和从酸泡菜中分离出的混合细菌群有较强的抑制作用，对大肠杆菌、沙门氏菌和黑曲霉的抑制作用较差，对啤酒酵母、红酵母和青霉无抑制作用；机皮提取物的抑菌作用受ｐＨ值的影响不大。

Abstract: The inhabitant activities of shaddock peel extracts (SPE) against bacteria, yeasts and molds were studied. the rcsults showed that SPE had strong inhabitant activities against Bacillus thurrngiensis,Staphylococcus aureas and bacteria from pickle, but weak against Escherichia coli, Salmenella entenitidis,Aspergillus niger and no inhabitant effects against Saccharomyces cerevisiae, Rhodo torula, Penicillium glaueus. The variation of pH did not significantly affect the functions of SPE on microorganisms.
