本厂1987年7月进行了金针菇下床料再栽草菇试验,采用镇江医学院余兆丰的简易通气发酵工程制作的草菇液体种,收到了很好效果,生物效率达13.5—16.7%。(一)液体种的制作:草菇种为V_(23)—8701(自选)。(2)液体培养基为麦麸粉1%、白糖2%、酵母粉1%、蛋白胨0.2%、磷酸氢二钾0.1%、硫酸镁0.1%、豆油0.5%,灭菌前pH7.0,灭菌后pH6±0.5。(3)主要设备有增氧机、过滤器、发酵瓶。气量0.3升/分钟,按余兆丰三管密闭式专利方法进行通 The factory in July 1987 under the mushroom material to bed and then planted straw mushroom test, the use of Zhenjiang Medical College Yu Zhaofeng simple aeration fermentation made of straw mushroom liquid species, received good results, the biological efficiency of 13.5-16.7%. (A) the production of liquid species: straw mushroom species V_ (23) -8701 (optional). (2) liquid medium is 1% of wheat bran powder, 2% of sugar, 1% of yeast powder, peptone 0.2%, potassium hydrogen phosphate 0.1%, magnesium sulfate 0.1%, soybean oil 0.5% After the bacteria pH6 ± 0.5. (3) The main equipment aerobics, filters, fermentation bottles. Gas volume of 0.3 liters / minute, according to Yu Zhaofeng closed three-tube patent way through
