Održiva proizvodnja bioetanola i biokemikalija iz otpadnih poljoprivrednih lignoceluloznih sirovina

Opis projekta
The aim of this project proposal is the development of sustainable bioprocesses for the production of bioethanol and biochemicals [lactic acid (LA) and physiologically active oligosaccharides (PAO)] from agricultural waste lignocellulosic raw materials (e.g. wheat straw, corn stover and cob, onion peels, cocoa husks, pea pods, walnut shells and sugar beet pulp). All these agricultural byproducts are abundant, cheap, non-food competing and renewable polysaccharide-based feedstocks. In this project, agricultural waste lignocellulosic raw materials will be hydrolyzed by thermal, chemical or enzymatic methods or their combinations in order to obtain adequate disintegration of raw materials. Studies of bioethanol and LA production will be performed by the semi-solid or solid state fermentation in the new constructed horizontal rotating tubular bioreactor (HRTB). The most suitable microorganisms for bioetahnol and LA production will be identified and improved by genetic methods. Studies regarding suitable purification methods for all three bio-products will be performed in order to obtain pure compounds for theirs further practical use. Integration between production and separation bioprocess stages will be also examined in order to improve ecological and economical aspects of these bioprocesses. The sustainability of bioethanol and LA production will be evaluated through the realization of Life Cycle Assessment (LCA). The most efficient and sustainable bioprocess configuration will be determined and consequently scale-up procedure will be proposed. The scale-up procedure will be based on the developed integral bioprocess mathematical model and other scale-up criteria. Project outcomes will be new integrated bioprocesses for the transformation of agricultural waste lignocellulosic raw materials into high added value products.
