چکیده انگلیسی
Stereum hirsutum and Trametes versicolor, were studied over a period of 3-7Â weeks for pretreatment of radiata pine wood chips. Chemical analysis of pretreated biomass showed that the two studied strains were able to selectively degrade lignin. Selective lignin degradation was greater in week 3 of the pretreatment by Trametes versicolor compared to the other strain. Lengthening pretreatment time increased both lignin and cellulose losses which caused a reduction in selective lignin degradation for both strains. X-ray diffractometry showed that after seven weeks of pretreatment, the crystallinity of the woody biomass was decreased significantly. It decreased from 46% for untreated wood chips to 37% and 44% for Stereum hirsutum and Trametes versicolor treated biomass, respectively. The pretreatment with these two white rot fungi showed that 3-week pretreatment provided a cellulose rich biomass with the minimum cellulose loss compared to the other time of pretreatment.
