Technology of producing Edible Fungi from Distiller's grains

1. Fresh brewer's grains adjust ph 8-9 with lime, add 3% corn powder and appropriate amount of sawdust according to wet weight, and adjust about 65% of the culture material.

2. After weighing the dry white distiller's grains, add 15% corn powder, 4% lime powder and 130% water to build a pile for fermentation.

3. The effect of high yield can be obtained by inoculating bacteria with bag aerated material, two-stage full transformation cultivation by border soil cover film mushroom production method or conventional mushroom production management.

In order to make it easy for mushroom farmers to master, this paper focuses on the high-yield methods of cultivating Pleurotus ostreatus with fresh distiller's grains:

Culture material formula: 100 kg of fresh distiller's grains, 55 kg of sawdust, 12 kg of corn meal, 20 kg of cereal and grass section, 6.50 kg of urea, 1 kg of phosphate fertilizer and 3 kg of lime are the best formula.

Method of operation: ⑴ first add 2 kg of lime powder to the sawdust and then add fresh distiller's grains to mix well and pile up for 24 hours. ⑵ cereal grass section is about 3cm, soak in 1% lime water for 24 hours, make it fully soften, drain until the grass is not dripping by hand. ⑶ is then mixed with sawdust and lees, and urea and phosphate fertilizer are mixed 4 hours before bagging. Before bagging, the water content of the medium is 60% and the ph value is 8. ⑷ sterilization inoculation: use atmospheric pressure sterilization 100C, keep for 6 hours. When the temperature of the material was cooled to 25-28 ℃, the inoculation was carried out according to the aseptic operation method, and the bacteria were distributed in the culture room of 22 ℃. Generally, the mycelium grew into a bag in 18 days, and the mushrooms were produced in about 25 days, and were managed according to the routine method.
