The effect of culture conditions for the mycelium growth of Phillenus linteus.

Abstract

Phellinus linteus (Berk. & Curt.) Teng mushroom belonging to the genus Phellinus spp., has high medicinal value. This study was carried out with the aim to evaluate the effects of carbon, nitrogen sources, pH, and temperature on the mycelial growth of the P. linteus strain. The experimental results showed that glucose and casein with concentrations of 2.0 and 0.2% respectively are identified as the most suitable carbon and nitrogen nutrient sources for P. linteus. Conversely, the mycelia of P. linteus are not able to grow on the urea media. Mycelium of P. linteus growths well at 7-10 pH and temperature at 30oC. When mycelia are incubated in these conditions, the rate of mycelial growth of P. linteus reaches 5.0 mm/day with thick density even distribution, and adherence to the substrate firmly.
