木质纤维素酶诱导物对平菇菌包发菌期的影响

Effects of Lignocellulase Inducer to Oyster Mushroom Spawning Management Period

摘要: 在当前转化利用农林废弃生物质资源工厂化生产平菇菌包过程中存在菌包发菌期长的实际问题，缩短菌包发菌期是菌包生产企业的现实需要。向平菇液体菌种培养体系添加适宜的木质纤维素酶系诱导物，包括微晶纤维素、纤维二糖、羧甲基纤维素钠或木质素磺酸钠，对比分析菌包发菌期时长和出菇产量指标。结果表明在I期液体菌种培养物能正常接种前24 h添加微晶纤维素(0.1%)或纤维二糖(0.1%)作为诱导剂，既都能缩短菌包发菌期3天，又能提升第一潮菇产量4%或11%。建立了缩短平菇菌包发菌期技术，能为菌包生产企业提质增效提供参考。

Abstract: There exists a problem of long spawning management period when factory production of the oyster mushroom spawning bags based on the agriculture and forestry waste biomass resources in the present, therefore the shortening of the period of spawning management is the reality demands for the spawning bags producing enterprise. The lignocellulase inducer such as microcrystalline cellu-lose, cellobiose, sodium carboxymethyl cellulose and sodium ligninsulfonate was added into the oyster mushroom liquid culture system respectively, the time of spawning management period and the yield of fruit body were detected. The result showed the treatment of adding microcrystalline cellulose (0.1%) or cellobiose (0.1%) to the liquid culture at I stage that 24 h before the time used as normal inoculants, which could shorten the spawning management period by three days, and increased the yield of first tidal mushroom by 4% and 11% respectively. The technology of shortening the spawning management period is constructed in this study, which could provide reference data for the oyster mushroom spawning bags producing enterprise in order to enhance the quality and increase the effect.
