Acidogenic fermentation of starchy agroindustrial residues: metabolic profile & influence of thermal pretreatment

Volatile fatty acids (VFAs) are short-chain carboxylates consisting of six or fewer carbon atoms. They are produced either synthetically from fossil resources or as metabolic intermediates in the acidogenic fermentation (acidogenesis) step of anaerobic digestion process. These carboxylates are platform chemicals and have a wide range of applications such as in the production of biochemicals, bioplastics, biofuels, green solvents and biological nutrient removal [1]. The environmental and geopolitical impacts of the use of fossil resources as the raw materials have renewed the interest in bioresources such as agricultural and agro-industrial residues.
