Thermogravimetric analysis is commonly used to determine the kinetic constants of biomass pyrolysis. Fig. 3 shows the TG and DTG curves for monoculture and co-culture treated corn stover.There were three distinct stages of weight loss: the first stage of dehydration ranged from 25 to 150 ◦C, the second stage of active pyrolysis ranged from 150 to 400 ◦C, and the third stage of residual or passive pyrolysis ranged from 400 to 1000 ◦C. Due to hemicellulose degradation, there was a shoulder peak for the biopretreated
