Ganoderma applanatum is one of the most popular medicinal mushrooms due to the various biologically active components it produces. In order to study for the possibility of artificially cultivating G. applanatum, we investigated the growth status of G. applanatum mycelium using oak sawdust bottle(850 ml). It took approximately 17~27 days for G. applanatum cultivation and 15~16 days for G. lucidum cultivation with sawdust until the mycelial growth was complete. The weight of dried fruiting bodies showed that G. applanatum GBGA-01 weighed 16.0±7.4 g, and G. lucidum ASI 7125 weighed 7.9±2.7g. The thickness of the pileus was measured as 10.6±2.6 mm for G. applanatum GBGA-01, 16.3±8.7 mm for G. applanatum ASI 52823 and 8.6±3.5 mm for G. lucidum ASI 7125. The color of Ganoderma spp. showed that L degree was 55.5±1.1 for the contex of G. applanatum GBGA-01, 47.7±2.2 for the contex of G. applanatum ASI 52823 and 39.6±2.9 for the contex of G. lucidum ASI 7125.

To determine the optimal media conditions for the detection of the cellulolytic activity in Ganoderma lucidum, we varied three media conditions: dye reagent, pH, and temperature. First, we evaluated the use of four dyes, Congo Red, Phenol Red, Remazol Brilliant Blue, and Trypan Blue. To observe the effect of pH on the chromogenic reaction, we also made and tested various media spanning acidic and alkaline pHs, ranging from 4.5 to 8.0. Furthermore, in order to research the effect of temperature on the clear zone and the fungus growing zone, we tested temperatures ranging from 15 to 35℃. On the whole, the best protocol called for Ganoderma lucidum transfer onto media containing Congo red with pH adjusted to 7.0, followed by incubation at 25℃ for 5 days. Our results will be useful to researchers who aim to study extracellular enzyme activity in Ganoderma lucidum
