摘　　要：用甘蔗渣做诱导剂比较研究了大型腐生真菌（ＰｌｅｕｒｏｔｕｓＳｏｊｏｒ一ｃａｊｕ）同木霉菌（Ｔｒｉｃｈｏｄｅｒ－ｍａＶｉｒｉｄｅ）纤维素酶活力的差异，结果表明：１．大型腐生真菌产酶开始时间不如木霉菌早，产酶高峰也比木霉菌来得晚，但产酶时间长；２．在加有１％浓度四硼酸钠的碱性培养基上，不论木霉菌还是大型腐生真菌，其纤维素酶活力均最高；３．不同类型的碳源对大型腐生真菌的酶活性无明显影响，但低浓度的盐。The cellulase activity was compared between Pleurotus spp. and Trichoderma spp.cul-tured in basal medium with sugarcane residue. Pleurotus spp.exhibited a delay in cellulaseactivity and enzyme peak with a protracted cellulase activity span as against Trichodermaspp. The cellulase activity of both fungi was highest in alkaline medium with l%b0rax solu-tion,and different carbon sources did not show any notable impact on cellulase activity inPleurotus spp. whereas salts at low concentration,particularly sodium acetate acid, wereconducive to the cellulase, hvdrolvsis of CMC.
