摘要
Abstract
Two fungi,WPC-11 and WPC-12,were isolated and purified from decayed wood-plastic composites.Based on the characteristics of plate colony and micromorphology,as well as the analysis of ITS and 18S rDNA sequences,WPC-11 was identified as Perenniporia sp.species,while WPC-12 was identified as Fomitopsis sp.strain.The decay properties of two decay fungi were tested by method of natural wood decay resistance test.The changes of microstructure and chemical composition of wood samples before and after fungal decay were analyzed by scanning electron microscopy(SEM)and Fourier infrared spectroscopy(FTIR).The results showed that WPC-11 and WPC-12 had caused 39.06%and 47.39%weight losses for Hibiscus tiliaceus wood,respectively.SEM showed that the surface and interior of the wood specimens after decay had been degraded.Meanwhile,the FTIR results indicated that chemical components in wood samples have been degraded by decay fungi.关键词
