Daily methane content from different ratios of corncob by
anaerobic fermentation within 29 days was shown in Fig. 3.
Methane production of all the experiments performed almost the
same production regular by its specific content in biogas. The
methane contents were rapidly rising when the anaerobic fermentation
began. The methane contents of the ratios maintained at the
level about 60% until the end of the reaction.
However, different ratios of corncob and PM lead to different
biogas production after anaerobic fermentation. In order to find
out the proper ratio between corncob and PM from different ratios
for anaerobic digestion, analysis of the gas production result is
essential.
