| Abstract: | Bamboo has received increasing attention as an alternative raw material for wood in the late twentieth century for its fast growing nature and good mechanical properties. But bamboo is readily discolored by mould fungi, which greatly limits the applications of bamboo. In this paper, mould-resistance of moso bamboo treated with chitosan-copper complex (CCC®), propiconazole (PPA), tebuconazole (TBA), the compound of CCC® and PPA or TBA was reported. Results showed that CCC® or PPA used alone as bamboo-mould inhibiter could defer or restrain the growth of Penicillium citrinum Thom (P. citrinum), while not being effective against Trichoderma viride Pers. ex Fr (T. viride) and Aspergillus niger V. Tiegh (A. niger). However, the compound of CCC® and PPA could inhibit all mould fungi in the test, showing a good synergetic effect. Additionally, TBA had better resisting effect against P. citrinum and T. viride than against A. niger, but showed no synergetic effect with CCC®. |
