英文摘要	Podaxis pistillaris is a fungus commonly found in most desert areas worldwide. The oval shaped peridium, the rigid woody stipe, plus a 10-15 mu m spore size stand out among its morphological features. Even though this fungus is used for human consumption and for several traditional remedies, a lack of knowledge regarding its fibrolytic enzymatic system still prevails. This fungus was collected from the central region of the Sonoran desert (29 degrees 07.23'97 '' LN and 110 degrees 53.58 ' 02 '' LW, 238 masl). In order to study its enzymatic system on common fibers, P. pistillaris was grown in a specific submerged culture in order to determine total cellulases, xylanases and laccases. The maximum cellulolytic (501.7 U.mg(-1)), as well as xylanolytic (157.8 U.mg(-1)) activities, were detected after 18 cultivation days, whereas the highest laccase specific activity (179.6 U.mg(-1)) was registered after 15 days at 40 degrees C. The thermostability of total cellulases, xylanases and laccases was found within temperatures ranging from 40 to 60 degrees C. The present study represents the first report of P. pistillaris fibrolytic activity in submerged culture.
