Characterization of the structure of rice and wheat straw pretreated
with Trichoderma sp. AH
Abstract
In this study, the effect of PT with Trichoderma sp. AH on structure of
rice wheat (RS) and wheat straw (WS) was investigated. TG/DTG analysis
shows that PT could incompletely degrade RS and WS with no significant
effect on their group composition. XRD analysis shows that PT could
incompletely destroy the crystal structure of RS and WS causing lower
crystallinity, which clearly suggests that PT is effective in disrupting
the structure. The effect of PT on RS and WS is primarily on cellulose
and hemicelluloses decrystallization to amorphous material. XPS analysis
shows that PT has some influence on the oxygen- and nitrogen-containing
compounds with increasing the relative contents of some oxygen- and
nitrogen-containing compounds. PT is an effective preparation for
biomass liquefaction by destroying the structure of biomass with minimal
loss of carbohydrates.
