Volatile fatty acids (VFAs) are inevitable intermediates of biogas production during the anaerobic digestion organic matter. The excessive accumulation VFAs leads to a pH drop and strong inhibition methanogenesis. On other hand, useful commodities with different applications, their fermentative may compete traditional methods based on oil derivatives. fermentation have commonalities biorefinery concept. present review considers VFA together competitive simultaneous hydrogen production. Methods enhanced volatile presented, showing option integrated processes product removal energy from obtained biogas. basis review, following conclusion can be drawn. (formic, acetic, propionic, butyric ones) various applications. That is why targeted desired rate shift aims toward instead release. combined release make overall process self-consistent, sufficient maintain target using for heating digestor. maintenance optimum concentrations accomplished by broth, thus integrating recovery operation conditions in digester. substrate preparation operating (organic loading hydraulic retention time) crucial importance successful process.
