摘　　要：Two white-rot fungi Coriolus versicolor B1 and Ganoderma lucidum En were used for biological pretreatment of bamboo. The saccharification rate,the relative contents and the degradation rates of cellulose,hemicellulose and lignin in untreated and pretreated bamboo,were determined. The results indicated that the relative content of cellulose in bamboo was 35.7%,which was just a little lower than hard wood,and bamboo was suitable for cellulosic ethanol production. The saccharification rate of bamboo was significantly improved after biological pretreatment with white-rot fungi. After pretreatment with G. lucidum En for twenty days,the saccharification rate was enhanced for 26.9%. After pretreatment with C. versicolor B1 for thirty days,the saccharification rate was enhanced for 19.2%. These results revealed that biological pretreatment with white-rot fungi was very efficient for promoting enzyme hydrolysis of bamboo and it’s an efficient pretreatment method for bamboo.Two white-rot fungi Coriolus versicolor B1 and Ganoderma lucidum En were used for biological pretreatment of bamboo.
