摘　　要：采用抑菌圈法研究了壳聚糖金属盐防霉剂对木霉Trichoderma viride,青霉Penicillamcitrinum,黑曲霉Aspergillus niger,黄曲霉Aspergillus flavus以及酵母菌Microzymesp.的抑菌作用,并筛选出最佳抑菌质量分数。结果表明壳聚糖铜盐对于所选菌种的抑制效果高于其他几种试剂,且抑制持续性也较长;质量分数为20.0 g.kg-1时,壳聚糖对木霉和酵母菌的抑菌效果特别明显,且抑制持续性也最长;壳聚糖锌盐对木霉和酵母菌的抑菌效果高于硼酸;硼酸只对黑曲霉有较长的抑制持续性。The restraining effects of Chitosan metal salts series on Trichoderma viride, Penicillam citrinum, Aspergillus niger, Aspergillusflavus and Microzyme sp. were studied. Results showed as the follows： chitosan Cu salt had good restraining effects to all chosen fungi than other fungistat, and the persistence of restraining was longer. Chitosan with the concentration of 20.0 g·kg^-1 had the best effects to Trichoderma viride and Microzyme sp. and with the longest persistence. Chitosan Zn salt had better effects to Trichoderma viride and Microzyme sp. than boric acid. Boric acid only had some effects to Aspergillus niger. [ Ch, 9 fig. 11 ref. ]
