本文研究了糙皮侧耳在玉米秸—麦麸基质上生长期间,菌体对基质的转化放率和基质中主要组分的降解规律。实验结果氧明:1.头潮菇子实体绝对生物学效率为9.15％,二潮菇子实体绝对生物学效率为4.10％。2.头潮菇子实体阶段所消耗的营养物质有57.61％是来自于木质纤维素的降解,另42.39％是来自于基质中的非木质纤维素组分。二潮菇期间所消耗的营养物质有86.82％是未自于木质纤维素的降解,另13.18％是来自于基质中的非木质纤维素组分。3.在菌丝体生长阶段和头湖菇的原基期,培养物中CMC酶、FP酶和半纤维素酶活性甚低,在子实体迅速生长阶段,该三种酶的活性迅速增加,在子实体成熟期左右培养物中出现酶活性高峰,在头潮菇子实体采收后酶活性迅速下降,在二湖菇子实体迅速生长期间,培养物中酶活性再次增加,在子实体成熟期基物中再次出现酶活性高峰。由此可见,酶活性增加与子实体生长发育有十分密切的关系。
In this paper, the degradation rate of the transformation rate of the substrate and the main components in the substrate during the growth of Pleurotus ostreatus on corn stalk-wheat bran substrate were studied. Experimental results Omi: 1. The tidal flat mushroom fruiting body absolute biological efficiency of 9.15%, two tide fruiting bodies absolute biological efficiency of 4.10%. The fruiting bodies of tide fruiting bodies consumed 57.61% of the nutrients from the degradation of lignocellulose, and the other 42.39% from the matrix of non-lignocellulosic components. 86.82% of the nutrients consumed during the second wave of mushrooms were not degraded from lignocellulose, and the other 13.18% came from non-lignocellulosic components in the matrix. 3. In the mycelium growth stage and the initial stage of the head lake mushroom, CMCase activity, FP enzyme and hemicellulase activity in the culture is very low, the activity of these three enzymes increased rapidly in the rapid growth stage of fruiting body, During the ripening stage of fruiting bodies, the peak of enzyme activity appeared, and the enzyme activity decreased sharply after the fruiting body of Harvest capitata harvested. During the rapid growth of fruiting body, the enzyme activity increased again, The peak of enzyme activity appears again in the substrate. Thus, the increase of enzyme activity and fruiting body growth and development have a very close relationship.
