适于香菇菌棒生产接种的液体菌种培养基配方筛选

Screening of Liquid Culture Medium for Inoculating Cultivation Bags of Lentinus edodes

选取6种常用的香菇液体菌种培养基,通过对菌丝生物量、菌棒培养状况和出菇状况的比较,筛选适合香菇菌棒的最佳液体菌种培养基配方。结果表明,配方3(玉米粉2%、马铃薯淀粉2%、酵母膏0.2%、麸皮1%、磷酸二氢钾0.1%、硫酸镁0.1%)适于香菇菌棒的直接接种,其上接种的香菇菌棒整个生长周期仅为205天。

Six kinds of common liquid culture media were tested to screen optimum one for Lentinus edodes through comparing mycelial biomass,cultivation conditions and growth conditions of fruiting bodies.The results showed that the optimal formula was 2% of corn flour,2% of potato starch,0.2% of yeast extract,1% of bran,0.1% of potassium dihydrogen phosphate and 0.1% of magnesium sulfate; and the growth cycle of cultivation bag was 205 days on it.
