以3~4年生新伐毛竹为试材,以青霉、木霉、黑曲霉为试菌,与常用的竹材防霉剂硼酸(HBO3)、百菌清等进行比较,对壳聚糖金属配合物(CMC)系列的壳聚糖铜配合物(CCC)、壳聚糖锌配合物(CZC)的防霉性能进行测试.结果表明:CCC和百菌清对木霉、青霉、黑曲霉防治效果均优于CZC、壳聚糖和硼酸;相比之下,CCC对青霉防治效果优于百菌清,而百菌清对木霉防治效果优于CCC.
Chitosan metal complexes (CMC) are the metal salts chelating with chitosan that is a non-toxic, polyaminocarbohydrate derived from the natural product chitin, which is the second most abundant natural polymer after cellulose and mainly exists in crustacean shells. Available researches showed that CMC such as chitosan copper complex(CCC) and chitosan zinc complex(CZC) as a potential environment friendly wood preservative taking place of CCA in future had high effectiveness against both attacks from wood rotting fungi and termite. The anti-mold effects of chitosan Copper/zinc complex ( CCC and CZC for short) on bamboo wood of Phyllostachys pubescens were reported in this paper. Results showed that the anti-mold effects of CCC and chlorothalonil on Trichoderma viride Pets. ex Ft., Penicillium citrinum Thom. and Aspergillus niger V. Tiegh. were all better than that of CZC, chitosan and boric acid. The anti-mold effects of CCC to Penicillium citrinum Thom. was better than that of chlorothalonile, while bamboo wood treated with chlorothalonile had higher resistance to Trichoderma viride Pers. ex Fr. than that of treated with CCC.
