链孢霉是危害食用菌生产的一种主要杂菌.近几年我们在生产中发现,该菌不但在夏秋高温、高湿环境中容易发生,而且在冬春温度较低时也有大量发生,常给生产带来严重威胁.为此,我们对影响该菌发生的几种环境因子,进行了初步研究.(一)链孢霉症状及发生条件该菌为半知菌亚门,丝孢目,丝孢科,丛梗孢属的一种.主要以无性 In recent years we found in production, the bacteria not only in the summer and autumn high temperature, high humidity environment prone to occur, but also in winter and spring when the temperature is low, there are a large number of occurrence, Often give a serious threat to the production.To this end, we have a preliminary study of several environmental factors that affect the bacteria. (A) Syphilis symptoms and occurrence conditions The bacteria for the penicillium subfamily, , Cyanobacteriaceae, a species of Pichia species. Mainly asexual
