【摘要】 通過對杏鮑菇生產過程中菌絲纖弱稀淡(弱菌絲)菌包的培養料進行微生物檢測和不同溫度培養試驗,探索了菌包培育過程中出現菌絲纖弱稀淡和培育周期延長的原因。結果表明,引起菌絲生長緩慢和纖弱稀淡的根本原因是培養料滅菌不徹底,料包在冷卻過程中細菌大量增殖;常壓滅菌的料包在冷卻過程中當培養料溫度在40℃~70℃區間時,引起"弱菌絲"現象的腐敗細菌快速增殖,55℃時為最佳增殖溫度,通過對冷卻過程溫度和時間的控制能有效避免"弱菌絲"現象,確保產量和質量的穩定。
【Abstract】 Through microbe detection and different temperature cultivation,the reason of causing weak mycelium were explored.The results showed that the weak mycelium originated from incomplete sterilization of culture medium.During the cooling process of medium,suitable temperature provided the advantage for the bacterial proliferation.When the medium at a temperature between 40℃ and 70℃,the pathogenic bacteria reproduced quickly,and reached the top at 55℃.So it was effective to avoid weak mycelium by rap...
