Effects of companion fungus on several enzymatic activities of Grofola umbellata / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the effect of companion fungus on several enzymatic activities of Grifola umbellata.</p><p><b>METHOD</b>Chitinase, beta-1,3-glucanase, proteinase and extracellular enzymes of G. umbellata were measured during dual culturing with companion fungus.</p><p><b>RESULT</b>Companion fungus could induce the increase of chitinase and beta-1, 3-glucanase activities of G. umbellata. noevident changeswere found in proteinase activity. When in liquid culture, the activities of extracellular enzymes in dual cultured filtrate were between of these of G. umbellata and companion fungus in monocultures.</p><p><b>CONCLUSION</b>Sclerotia differentiation related materials supplied by mutual nutritional supplement between G. umbellata and companion fungus conduce to sclerotial formation of G. umbellata.</p>
