(一)酶:平菇是弱寄生木腐菌,早年Camphell(1933)已注意到平菇对木材中纤维素和木素有较强分解能力。Rajarathnam等(1979)将白色匙状侧耳(P.flabellatus)接种在稻草上,经4小时就出现纤维素酶和半纤维素酶活性。Zadrazil(1976.1980)发现,白黄侧耳(P.Comucopiae)可使油菜和向日葵秆成分分解分别达44.5％和43.2％;佛罗里达侧耳能分解麦秸中的全纤维素和a-纤维素,并能分解木素。 Wojtai-Wasilewska.M等(1975)指出,糙皮侧耳利用木素,是通过漆酶和过氧化物酶两者间存在的刺激而起作用的。侯文英等(1981)发现,在菌丝体发育时期漆酶保持较高的活性,从而使木素降
(I) Enzymes: Pleurotus ostreatus is a weakly parasitic wood rot fungus. Earlier Camphell (1933) noticed that Pleurotus ostreatus had a strong ability to decompose cellulose and lignin in wood. Rajarathnam et al. (1979) inoculated P.flabellatus on straw and showed cellulase and hemicellulase activity over 4 hours. Zadrazil (1976.1980) found that P.Comucopiae could decompose rapeseed and sunflower stalk components by 44.5% and 43.2%, respectively; Florida pleurotus could decompose whole cellulose and a-cellulose in wheat straw and decompose wood Prime Wojtai-Wasilewska.M et al. (1975) pointed out that the use of lignin by Pleurotus ostreatus works through the presence of stimuli between laccase and peroxidase. Hou Wenying et al. (1981) found that laccase maintained high activity during mycelial development so that lignin
