摘　　要：研究了 2种抗菌防腐剂凯松、双乙酸钠对几种常见细菌、真菌和椰衣纤维中霉菌的抑菌作用 结果表明 :凯松的抑菌作用最强 ,它对细菌、酵母菌、椰衣纤维霉菌均有很强的抑制作用 ;双乙酸钠对椰衣纤维中霉菌有较强的抑制作用 ,但对细菌和酵母需要较高浓度才有抑制作用 这 2种抗菌防腐剂的抑菌作用都有较好的热稳定性 ,因此 。This paper studies the bacteriostasis of Kathon and Sodium Diacetate on several common microbes. The result shows that Kathon has the stronger bacteriostasis on bacteria, yeast, and mold from Cocos nucifera L. fiber among these two antimicrobial agents. Sodium Diacetate can create comparatively strong bacteriostasis on mold from Cocos nucifera L. fiber, but has bacteriostasis on bacteria and yeast only in the high concentration. The bacteriostasis thermal stability of both the antimicrobial agents is comparatively high. Thus, Kathon and Sodium Diacetate can be widely used as a new antimicrobial agent.
