Mucor is a kind of miscellaneous bacteria that often occurs in the production and cultivation of various mushroom strains such as oyster mushrooms, mushrooms, mushrooms, and straw mushrooms. The contaminated culture material initially formed white mycelium on the surface, its growth rate was significantly faster than that of edible fungi, and it could occupy the entire space where the edible fungi grew in a few days, and later formed many black conidia on the surface of the mycelium. Mucor can survive on rice straw, compost, and plant residues. After the spores mature, they flow with the air flow. Insect culture materials, inoculation rooms, etc. are not completely disinfected, or they are not strictly inoculated and seeded according to aseptic procedures. They are all contaminated with mucor. Possible. As long as the humidity of the substrate surface is suitable, the spores can germinate and grow into hyphae, which grows rapidly and spreads quickly under high temperature and high humidity conditions. In order to prevent the growth of mucilage against the growth of edible fungi, comprehensive measures should be taken. Do a good job of environmental sanitation, keep cleanliness around the cultivation room and the cultivation pool, and dispose of the waste in a timely manner; the inoculation room and mushroom house should be cleaned and disinfected according to regulations; the operator must ensure thorough sterilization during the seed production, and the bagged bacteria species must be handled during handling. Handle gently to prevent cracking of the plastic bag; properly increase the pH of the culture material, add 1% to 3% of quicklime or spray 2% of lime water during mixing, which can inhibit the growth of mixed bacteria; use dry material weight 0.1% The thiophanate-methyl spices have better control effect. When mucilage is produced on the mushroom bed culture material, it should be ventilated and dried in time, and the room temperature should be controlled at 20-22°C. After the growth of the fungus is inhibited, normal management can be resumed. 3.0T MRI,3.0T MR Imaging,Longer Magnet System,3.0T MR Imaging Systems MinFound Medical Systems Co., Ltd , https://www.minfoundmed.com
