杂菌污染是“九二○”土法生产中的大敌,是影响“九二○”产量和质量的重要因素。严重时会使发酵单位显著降低,甚至迫使发酵中断。世界上怕就怕“认真”二字,对此,我们必须高度重视,认真对待,做过细的工作,以防止杂菌污染。1、污染的主要表现和常见杂菌:杂菌污染在一、二级种子管(瓶)及大床发酵过程中都会发生,尤其是在温暖潮湿的梅雨季节里,由于空气中的杂菌孢子增多,很易引起污染。
Bacteria contamination is the enemy of “920” indigenous production, which is an important factor affecting the yield and quality of “920”. In severe cases, the fermentation unit will be significantly reduced, and even forced fermentation disruption. For the fear of being “conscientious” in the world, we must attach great importance to and take it seriously and do the fine work to prevent it from being polluted by bacteria. 1, the main manifestations of pollution and common bacteria: bacteria pollution in the first and second seed tubes (bottles) and bed fermentation process will occur, especially in the warm and humid rainy season, the bacteria in the air due to spores Increase, it is easy to cause pollution.
