摘要：To better understand the comparative effects between pretreatment and bioaugmentation methods on the promotion of corn straw biogasification efficiency, we analysed the cellulase activity, cellulose degradation rate, surface structure characteristics, and biogas production of corn straw that had been pretreated with aerobic microbial consortium (AMC). In addition, we also studied the effect of bioaugmentation using anaerobic microbial consortium (ANMC) on corn straw biogasification efficiency. The results from our study demonstrated that the cumulative methane generated from AMC and ANMC were 233.09 mL·g-1 VS and 242.56 mL·g-1 VS, which was increased compared to the control by 6.89% and 11.23%, respectively. We also observed that ANMC could also function to dramatically promote methane content during the anaerobic digestion of corn straw. This study demonstrated that AMC and ANMC were both able to promote the biogasification efficiency of corn straw, however, ANMC was found to perform better compared to AMC.
