What to Do When Oyster Mushroom Mycelium Breaks or Degenerates? Causes and Prevention Methods

After inoculation, normally growing mycelium is dense and pure white, advancing forward in a fan shape, and the cottonseed hull substrate decomposed by the mycelium turns yellowish-brown. If a section of mycelium breaks and becomes disconnected, it is called "mycelium break." This situation is caused by excessive water content in the substrate and high temperatures during cultivation. Choosing appropriate humidity and temperature can prevent the "mycelium break" phenomenon. The degeneration and shrinkage of mycelium that has already grown well on the substrate is called "mycelium degeneration." If the substrate is too dry and too loose, the mycelium that grows will be thin and weak; excessively high temperatures during cultivation, poor ventilation, or pest infestation

The degeneration and shrinkage of mycelium that has already grown well on the substrate is called "mycelium degeneration." If the substrate is too dry and too loose, the mycelium that grows will be thin and weak; excessively high temperatures during cultivation, poor ventilation, or pest infestation will all cause the "mycelium degeneration" phenomenon. Improving the above conditions can prevent "mycelium degeneration" from occurring.
