In the course of cultivation, edible fungus strains will be contaminated with various bacteria such as green mold, penicillium, Aspergillus, rhizopus, mucor, and bacteria, and the high temperature season is particularly serious. In the course of production, due to the infringement of the bacteria, it often leads to a reduction in production or even a loss. Incomplete sterilization Incomplete sterilization of culture materials can cause contamination with bacteria, usually 3 to 5 days of contamination. Incomplete sterilization is also caused by the following reasons: Improper handling of molds: Mycelia and spores of common bacteria can be killed at 100°C, 6-8 hours or 121°C and 0.5-2 hours at atmospheric pressure. At present, edible mushroom culture materials are often sterilized by atmospheric pressure or autoclaved. Atmospheric pressure sterilization is difficult to sterilize cereals, dung and other materials, and it is not easy to fully achieve the effect of sterilization. The effect of autoclaving is much better. The influence of the nature of the culture material: The type of material needed for seed production, the bacterial content in the culture material, the water content, and the pH value can all affect the sterilization effect. When sterilizing, according to the different formulations of culture materials, select the appropriate sterilization time. Improper stacking of strainer bottles (bags): The stacking form of strainer bottles (bags) in the sterilizer pot can affect the sterilization effect. There must be a certain gap in the discharge so that the steam can circulate and heat up. When sterilizing culture materials in bagged strains, plastic bags are easy to deform and become soft after being heated. If the materials are not loaded tightly, the gaps between the bacteria bags will be reduced when stacked and piled up, which will affect the sterilization effect. Effect of bacterial strainer strains or bacterial strainer bags: strain strainers or strainer strainers are generally selected for seed production. Plastic bags have a fast heat transfer rate, while glass bottles have a slow heat transfer rate. When using the same sterilization method for the same culture material, the bottle material is slightly longer than the bag material sterilization time. In addition, individual containers that are not tightly sealed or broken can also cause contamination with germs. Inoculation operation is not standardized The inoculation of edible fungi requires strict aseptic processing. If the operation is not standardized, contamination of the culture materials with bacteria can easily occur. The contaminated germs are generally the bacteria in the inoculation room, the bacteria on the surface of the bacteria bag, and the surface bacteria of the inoculation personnel. The contamination of culture materials caused by non-standard operation is the growth of bacteria on the surface of the culture material, which usually occurs at the opening of the bacteria bag and the vaccination site. Therefore, we must strictly abide by the aseptic procedure, and the inoculation room should use the "sterile special disinfection king" for strict disinfection. Bacteria with bacteria The original species used to expand the culture must be pure bacteria in order to ensure the unity of the species. If the strain itself is not pure, it may cause bulk pollution. In the batch of strains produced, the strains contaminated all appear to be contaminated, and the contaminated part is in the strain block where contamination occurs earlier. Inoculation 3~5 Days can appear. Therefore, we should try to use the best strains of viable strains, suitable strains, and strong resistance to stress. Unclean room The culture material is not clean, the air does not circulate, the room is damp, and bacteria can also be infected. The pollution rate in this case is relatively low, but as the incubation time increases, the pollution rate will gradually increase. A lot of pollution appeared later, and it usually appeared after 10 days of inoculation.
