Effect of Aquatic Extraction Substance from Residue of Pleurotus ferulae on Mycelium Growth of Four Edible Fungi

Objective:The solution of problem of reused vast residue of edible fungi was studied. Method:Effect of aquatic extraction substance from residue of Pleurotus ferulae on mycelium growth of four edible fungi were conducted by using plate method. Result: The mycelium growth of Lentinula edodes and Flammulinavelutipes increased markedly in PDA culture medium, which contained 10%～50% aquatic extraction substance from residue of Pleurotus ferulae. The mycelium growth of Pleurotus eryngii increased in PDA culture medium, which contained 10% extraction solution. But the mycelium growth of Coprinus Comatus was almost inhibited in PDA culture medium, which contained above 10% extraction solution. Conclusion: Residue of Pleurotus ferulae could be a part of substrate of Lentinula edodes and Flammulinavelutipes.
