Technical Regulations for Sterilization in Bagged Edible Mushroom Production
Whether sterilization in bagged edible mushroom production is thorough or not determines the success or failure of production. Sterilization means holding the production substrate at a certain temperature and pressure for a certain period of time to kill the spores of contaminating bacteria in the substrate, promote the growth of microorganisms (such as enoki mushroom and shiitake mushroom mycelium), increase yield and quality, and improve the grower's returns. Regardless of what type of sterilization stove is used, the principles of sterilization fall roughly into two categories: one is high-pressure sterilization, and the other is atmospheric-pressure sterilization. Atmospheric-pressure sterilization requires low investment, simple facilities, convenient operation, is safe,

Eight preventive measures for bagged shiitake mushrooms to safely overwinter the summer, explained in detail
Based on our investigation and analysis of the summer-survival problems in large-scale bagged shiitake mushroom cultivation in Xixia over more than ten years, we have summarized a set of preventive measures for bagged shiitake mushrooms to safely get through the summer. They are presented below for reference. 1. Prevent contaminated spawn. There are many factors that can cause contamination in spawn, for example: incomplete sterilization of the substrate, lax disinfection during inoculation, introduction of pathogens during inoculation operations, air forced in through the cotton plug, respiration or damage during spawn transport, inoculation with contaminated spawn, and other such reasons. If contaminated spawn is used for production, it can harbor incalculable losses. 1.1
