摘　　要：对竹基质白腐菌选择性降解进行了初步研究。结果表明,菌株B1对竹基质中木质素和半纤维素有明显的降解选择性。降解55 d木质素和半纤维素降解率分别达44.4%和47.1%;降解20 d降解选择性最好,木质素和半纤维素降解率选择系数分别是2.08和1.98。从FTIR图谱中木质纤维素相关谱峰(2 924、1 6351、6011、5101、165、1 045、666/cm等)的明显变化也可以得出相同结论。Selectivity degradation of bamboo white rot fungi was initially studied. The results indicated that strain B1 has apparent degradation selectivity for hemicellulose and lignin. Fifty-five days after the degradation of bamboo powder, the rate of both forenamed components was 47. 053% and 44. 391% respectively. Twenty days after the degradation, the degradation selectivity was the best; the degradation selective coefficient of hemicellulose and lignin was 2. 078 and 1. 983 respectively. The same conclusions were also obtained from apparent changes in related peak bands （2 924, 1 635, 1 601, 1 510, 1 165, 1 045, 666/cm etc.） of the FTIR atlas.
