and 34.6% shorter technical digestion time compared with the untreated sample.
Analyses of chemical compositions showed 5.81–25.10% reductions in total lignin, cellulose, and hemicellulose contents, and 27.19–80.71% increases in hot-water extractives; these changes contributed to the enhancement of biogas production.
Biological pretreatment could be an effective method for improving
biodegradability and enhancing the highly efficient biological conversion of corn straw into bioenergy.
