对污泥和/或泥浆产甲烷活性的全面测量被认为是了解替代生物质厌氧消化过程中涉及的厌氧联合体的基本生理的关键。在本研究中，利用沼气植物浆液的产甲烷活性，在标准的测定条件下，评价了骨胶原厂废弃物如肌腱、初级澄清骨废弃物(PCBW)和蓝藻生物量的厌氧消化。据报道，当骨胶原工厂废物与蓝藻生物量按特定比例混合时，产甲烷活性最高，其中仅有筋骨和PCBW也有利于显着的甲烷产量。蓝藻的生物量本身并不能产生理想的产甲烷活性。30天后，这些废物中约有48%的固体被销毁。本研究为骨胶原厂大规模厌氧消化过程中如何合理利用这些废弃物提供了有效的途径。
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.
