培养基的灭菌是食用菌生产过程中的一个重要环节。而目前在食用菌制种中对培养基的灭菌存在问题较多,本文着重谈谈培养基的加压蒸汽灭菌。加压蒸汽灭菌,一般称高压蒸汽灭菌,由于水蒸气在冷聚时能放出大量的气化热 Culture medium sterilization is an important part of edible fungus production process. At present, there are many problems in sterilizing culture medium in the production of edible fungi. This article focuses on the pressurized steam sterilization of medium. Pressurized steam sterilization, generally known as high-pressure steam sterilization, as water vapor in the cold poly-energy release large amounts of heat
