通过对杏鲍菇生产过程中菌丝纤弱稀淡(弱菌丝)菌包的培养料进行微生物检测和不同温度培养试验,探索了菌包培育过程中出现菌丝纤弱稀淡和培育周期延长的原因。结果表明,引起菌丝生长缓慢和纤弱稀淡的根本原因是培养料灭菌不彻底,料包在冷却过程中细菌大量增殖;常压灭菌的料包在冷却过程中当培养料温度在40℃～70℃区间时,引起“弱菌丝”现象的腐败细菌快速增殖,55℃时为最佳增殖温度,通过对冷却过程温度和时间的控制能有效避免“弱菌丝”现象,确保产量和质量的稳定。
Through the test of the culture material of mycelia of weak mycelium (weak mycelium) during the production process of Pleurotus eryngii, we found that the hyphae of mycelium and the prolonged incubation period the reason. The results showed that the root cause of slow growth of mycelium and weakness and weakness was that the culture material was not completely sterilized and bacteria proliferated in the cooling process. When the pressure of the sterilization material was cooled, During the period of 70 ℃ ~ 70 ℃, the spoilage bacterium which caused the phenomenon of “weak mycelium” proliferated quickly and was the optimal proliferation temperature at 55 ℃. The control of the temperature and time of the cooling process can effectively avoid the “weak mycelium” Phenomenon, to ensure the stability of production and quality.
