A two-step bioprocess
was investigated for recovering biogas and biodiesel from corncob
combined anaerobic fermentation and BSFL in this study. Batch
experiments on anaerobic fermentation were conducted to evaluate effects of different ratios between corncob and pig manure for biogas generation, then biogas residue was converted by
inoculating BSFL for the accumulation of grease. And the grease
was extracted for biodiesel. Furthermore, the lignocellulose
changes in two-step bioprocess were evaluated. All the methods
aimed to evaluate the potential of using low grade raw materials
for high grade bioenergy production.
