What You Need to Know
During the spawn run, mycelium metabolizes complex carbohydrates via enzymatic hydrolysis, producing ATP and biomass while maintaining a pH of 5.5–6.5. In the fruiting phase, the mycelium shifts to secondary metabolism, synthesizing polysaccharides and aromatic compounds that contribute to the characteristic mushroom flavor.
The Science
Primary Reaction
Glucose + O₂ → CO₂ + H₂O + ATP (glycolysis and oxidative phosphorylation)
