    non-isothermal thermogravimetry/derivative thermogravimetry (tg/dtg) measurements are used to determine pyrolytic characteristics and kinetics of lignocellulose. tg/dtg experiments at different heating rates with corn stover pretreated with monocultures of irpex lacteus cd2 and auricularia polytricha ap and their cocultures were conducted. heating rates had little effect on the pyrolysis process, but the peak of weight loss rate in the dtg curves shifted towards higher temperature with heating rate. the maximum weight loss of biopretreated samples was 1.25-fold higher than that of the control at the three heating rates, and the maximum weight loss rate of the co-culture pretreated samples was intermediate between that of the two mono-cultures. the activation energies of the co-culture pretreated samples were 16–72 kj mol−1 lower than that of the mono-culture at the conversion rate range from 10% to 60%. this suggests that co-culture pretreatment can decrease activation energy and accelerate pyrolysis reaction thus reducing energy consumption.
