Corn straw is mainly composed of hemicellulose, cellulose, and lignin, which together form a crystal structure with extremely high stability. Anaerobic fermentation is an important means of straw resource utilization. Due to the complex composition of corn straw, the hydrolysis rate during anaerobic fermentation is limited, which affects the gas production efficiency. Therefore, it is necessary to pretreat corn straw. This article analyzes the advantages and disadvantages of different pretreatment methods and their applications in anaerobic digestion in order to provide optimal pathways for the pretreatment of corn straw.
