Propionic acid is an important intermediate produced during anaerobic degradation of biowaste
and a precursor of a large amount of methane. Its accumulation during biomethanation is however
a common problem resulting in stagnation phases in biogas production. During this study the
deeper insight into the process of propionic acid degradation was intended by using modern
analytical chemistry standard microbiological approach and molecular biology for describing
and explaining the problem.
