摘要: 本文主要研究以玉米芯为主要原料种植平菇苏引6号,并研究种植基质的综合利用。结果表明,四次采菇的收获总量达到培养原料重量的116.7%;第三次采菇后基质中的低聚木糖生成率以木二糖计可达原料的4.86%(干基);用10倍量的pH5柠檬酸-磷酸氢二钠缓冲液,25℃浸提基质中的木聚糖酶可获得最高的收率,其中第二次出菇期间基质的木聚糖酶可达155.9U/g(干基)。

Abstract: The planting of Pleurotus mushroom Suyin No.6 based on the corncob medium and the comprehensive utilization of the media were investigated. The results indicated that the gross mushroom outputs in all four times were as many as 116.7% of the culture medium weight. The maximal transform rate of xylobiose was 4.86% during the third mushroom collection. The best extraction effect of xylanase in the culture medium was obtained when 10 times of pH5 citric acid-sodium hydrogen phosphate buffer were used and maintained at 25℃, while the xylanase was extracted in 155.9 U/g (dry basis) during the second mushroom collection.

Key words: corncob, edible mushroom, xylo-oligosaccharide, xylanase
