【摘要】 通過對(duì)杏鮑菇生產(chǎn)過程中菌絲纖弱稀淡(弱菌絲)菌包的培養(yǎng)料進(jìn)行微生物檢測(cè)和不同溫度培養(yǎng)試驗(yàn),探索了菌包培育過程中出現(xiàn)菌絲纖弱稀淡和培育周期延長(zhǎng)的原因。結(jié)果表明,引起菌絲生長(zhǎng)緩慢和纖弱稀淡的根本原因是培養(yǎng)料滅菌不徹底,料包在冷卻過程中細(xì)菌大量增殖;常壓滅菌的料包在冷卻過程中當(dāng)培養(yǎng)料溫度在40℃~70℃區(qū)間時(shí),引起"弱菌絲"現(xiàn)象的腐敗細(xì)菌快速增殖,55℃時(shí)為最佳增殖溫度,通過對(duì)冷卻過程溫度和時(shí)間的控制能有效避免"弱菌絲"現(xiàn)象,確保產(chǎn)量和質(zhì)量的穩(wěn)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...
