BIO-Biorefinery for recovering organically certified fermentation additives from biomass
Abstract
Organically certified biomass is being used to generate fermentation additives which will be applied and optimised for the production of organic yeast. Solid residues will be assessed for organic feed and alternatively for anaerobic digestion (biogas) application. The technical and economic feasibility of the product idea will be evaluated within the project. The BioFer project will develop bio certified nutrition concentrates to be applied for organic yeast fermentation. The widespread conventional yeast production provides bulk chemicals such as ammonia, urea or phosphoric acid amongst to cover nutrition needs in fermentation. Such sources are not allowed for the production of bio certified products. Organically certified biomass feedstocks (e.g. sweet sorghum, alfalfa, glover) are used to extract a pure plant derived nutrition concentrate, which will be chemically characterised. Consequently this nutrition cocktail will be used as additive in fermentation trails at lab scale to generate organic yeast (organic bakery yeast and fodder yeast).Main focus of the work is the selection of strains, the optimisation of the fermentation process and product quality. In addition, the solid residues from biomass extraction will be evaluated with regard to the application as organically certified animal feed. Alternatively the utilisation of the solid residue will be assessed for the production of energy via anaerobic digestion (biogas). Based on the project results, it will be possible to evaluate the technical and economic feasibility for the entire bio refinery pathway and to describe the potential regional embedding of the technology. The results should generate potential market proposition for organically certified nutrition concentrates in the future.
