A Mathematical Model for the Interactive Behavior of Sulfate‐Reducing Bacteria and Methanogens During Anaerobic Digestion
Anaerobic degradation of waste involves different classes of microorganisms, and there are different types of interactions among them for substrates, terminal electron acceptors, and so on. A mathematical model is developed based on the mass balance of different substrates, products, and microbes present in the system to study the interaction between methanogens and sulfate‐reducing bacteria (SRB). The performance of major microbial consortia present in the system, such as propionate‐utilizing acetogens, butyrate‐utilizing acetogens, acetoclastic methanogens, hydrogen‐utilizing methanogens, and SRB were considered and analyzed in the model. Different substrates consumed and products formed during the process also were considered in the model. The experimental observations and model predictions showed very good prediction capabilities of the model. Model prediction was validated statistically. It was observed that the model‐predicted values matched the experimental data very closely, with an average error of 3.9%.
