玉米浆发酵液对杏鲍菇菌丝生长的影响

Effect on Mycelium Growth and Nutritional Value of Pleurotus eryngii With Fermentated Corn Steep Liquor

玉米浆发酵液由玉米浸泡水经浓缩后再发酵制得,具有丰富氮源、矿物质等。试验在杏鲍菇栽培中采用玉米浆发酵液部分替代传统基质中的氮源,研究玉米浆发酵液对杏鲍菇菌丝生长的影响。结果表明,添加玉米浆发酵液可以使杏鲍菇菌丝洁白浓密茁壮、菌丝生长速度加快0.14 mm·d^(-1)、生长周期缩短10~14 d、产量增加6.46%、生物学效率高达99.2%。

Fermentated corn steep liquor is made from corn steep water after concentration and fermentation,which is rich in nitrogen and minerals.In order to study the effect of corn steep liquor fermentation on the growth of Pleurotus eryngii mycelia,corn steep liquor fermentation liquid was used to partially replace the nitrogen source in the traditional substrate in the cultivation of P.eryngii.The results showed that the mycelial growth rate of P.eryngii increased by 0.14 mm/d,growth cycle shortened by 10~14 days,yield increased by 6.46% and biological efficiency is up to 99.2%.
