Abstract: | Overall measurement of methanogenic activity of sludge and or slurry is thought as a key for understanding the basic physiology
of anaerobic consortia involved in anaerobic digestion process of an alternative biomass. In this study, the methanogenic
activity of biogas plant slurry was used to evaluate the anaerobic digestion of ossein factory wastes such as sinews and primary
clarified bone waste (PCBW) and cyanobacterial biomass in standard assay conditions. A maximum methanogenic activity was reported
here when ossein factory wastes mixed with cyanobacterial biomass in specific proportions in which sinews and PCBW alone also
favored to a significant methane yield. Cyanobacterial biomass alone did not give a desirable methanogenic activity. Approximately
48% of total solids were destroyed from these wastes after 30 days. This study gives information on the use of these wastes
with suitable proportions for taking an effort in a large-scale anaerobic digestion in an effective way of ossein factory. |
