Sawdust bag cultivation of Shiitake mushroom (Lentinula edodes) is getting increase. The mycelia browning on the substrate surface is important for the stable production. The development of methods for the rapid mycelia browning is quite required. In this study changes in intracellular enzyme during the mycelial browning were investigated to find the rapid mycelia browning. Mycelia of L. edodes was changed into brown color while it grew in agar and liquid media like sawdust substrates. Mycelia of L. edodes was started to change color at 25 days after inoculation and browning was occurred in whole mycelia colony at 30 days and browning was completed at 40 days. The activities of enzymes was evaluated in these periodically color changing mycelia. Laccase activity was highest at 15 days after inoculation on PDB, but it gradually decreased from 15 days. Tyrosinase activity drastically increased in period between 30 days and 40 days while mycelia browning was progressed. The kinds of phosphotase identified by electrophoresis were esterase, acid phosphotase, and alkaline phosphotase. Activities of phosphotase were increased before the initiation of mycelial browning but they were decreased after browning.
