Abstract: In this work,the suitable formula for cultivating Ganoderma lucidum was optimized by evaluating the hypha growth rate,climbing ability,density of hypha and aerial hypha biological conversion.The best results were shown for the cultivating with potatoes 200 g,glucose 20 g,agar 20 g,bagasse 20 g,peptone 3 g,KH2PO43 g,Mg SO41.5 g,and VB20.1 g per liter.Comparing to the dry weight,thickness and sporophore diameter of four kinds of Ganoderma lucidum,GL0003 and GL0102 were proved to be the most suitable species,and their best media components were bagasses 82%,vinasse 15%,lime powder 2%,sugar 15%.The total triterpenoid contents result showed little difference between this two cultivation methods,all of them which grown on bagasse were higher than10 mg / g; Comparing with basswood groups,the polysaccharide contents of bagasse groups were more than twice.The contents of the main heavy metal elements in Ganoderma lucidum grown on bagassewas lower than that on basswood,but its organic magnesium,zinc and selenium content were higher than the basswood group,among them,the content of organic selenium was 0.189 mg / g.
