Unleashing Dairy Manure's Biogas Potential: A Michaelis-Menten Modeling Approach by Javad Rezaeifar, Abbas Rohani, Mohammadali Ebrahimi-Nik

“…The results demonstrate that the Michaelis-Menten model exhibits sufficient predictive capability for estimating cumulative methane production during the digestion process. The model was then utilized to compare the average cumulative methane production across the investigated treatments using the least significant difference (LSD) method, as well as to calculate the quantity of methane production at 25%, 50%, 75%, and 90% of the final methane yield. …”
