摘要

利用抑菌圈法对糖基双子阳离子表面活性剂(SGCS)和糖基阳离子表面活性剂(SCS)对大肠杆菌(E.coli)和金黄色葡萄球菌的抑菌性能进行了评价。SGCS的抑菌性能优于SCS;抑菌圈随着SGCS碳链增长先增大后变小,C_(12)-SGCS具有较佳的抑菌性能。C_(12)-SGCS和C_(12)-SCS对硫酸盐还原菌(SRB)、铁细菌(FEB)、腐生菌菌群(TGB)、E.coli和禾谷镰刀菌的杀菌性能表明,C_(12)-SGCS的杀菌性能优于C_(12)-SCS,当C_(12)-SGCS的质量浓度为15 mg/L时对SRB,FEB和TGB的杀菌率均超过99%。SGCS抑菌杀菌更广谱高效,具有良好的应用前景。
        The antibacterial activities of sugar-based cationic gemini surfactants(SGCS) and sugar-based cationic surfactants(SCS) against Escherichia coli(E.coli) and Staphylococcus aureus were determined by the inhibition zone method. The antibacterial activity of SGCS is better than that of SCS. The inhibition zone of SGCS is increased and then decreased with the increasing carbon chain length of SGCS, and C_(12)-SGCS has the optimum antibacterial activity. The bactericidal activities of C_(12)-SGCG and C_(12)-SCS against sulfate reducing bacteria(SRB), Ferribacteriales(FEB), Saprophytic bacteria group(TGB), E.coli and Fusarium graminearum were evaluated. The bactericidal activity of C_(12)-SGCS is better than that of C_(12)-SCS. The bactericidal rates of C_(12)-SGCS at 15 mg/L against SRB, FEB and TGB are all above 99%. SGCS has a good application prospect because of its broad spectrum and high efficiency in bactericidal and antibacterial actions.
