In methanogenic environments, propionate is an important intermediate product which is a volatile fatty acids (VFA). Degradation of propionic acid is difficult as they tend to accumulate during anaerobic digestion process. Accumulation of VFA will often result in a drop in pH and at low pH values, V...
