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
