Patent ID: 8318465

Claim:
A process for integrated utilization of the products of an enzymatic hydrolysis of renewable raw materials used in preparing a proteinogenic amino acid, comprising: a) preparing an aqueous hydrolysis mixture of the renewable raw materials, wherein the aqueous mixture comprises at least one carbon source utilizable by a microorganism used in preparing the proteinogenic amino acid; b) subjecting the aqueous mixture to enzymatic hydrolysis, producing a hydrolysate and a hydrolysate residue thereby; c) separating the hydrolysate and the hydrolysate residue; d) subjecting the hydrolysate to aerobic fermentation by a microorganism, producing the proteinogenic amino acid and a biomass thereby; and e) subjecting the hydrolysate residue to anaerobic fermentation by a microorganism, producing a biogas thereby.
