Abstract
Posljednjih nekoliko godina eutektična se otapala intenzivno proučavaju kao zelena zamjena za sveprisutna tradicionalna škodljiva otapala u procesima organske sinteze i biokatalize te stoga privlače znatnu pozornost unutar biotehnološke i kemijske industrije. Biokataliza se pokazala kao ekološki prihvatljiva alternativa kemijskim katalizama, a posebna pozornost se posvećuje biokatalizi u nevodenim otapalima. U okviru ovog rada ispitana je redukcija etil-acetoacetata u etil-3-hidroksibutanoat u različitim eutektičnim otapalima primjenom pekarskog kvasca Saccharomyces cerevisiae kao biokatalizatora. Kolinijevi DES-ovi sa mnosaharidima (ksiloza, fruktoza i glukoza) i sa alkoholom glicerolom su se pokazali kao dobra zelena otapala, dok su u ostalim ispitanim DES-ovima dobivena mala iskorištenja.
Abstract (english)
In recent years, deep eutectic solvents have been intensively studied as a possible replacement for conventional molecular solvents for biocatalytic and organic reactions and have been the subject of considerable attention within chemical technology and biotechnology. Biocatalysis proved as environment friendly alternative to chemical catalysis and special attention has been devoted to biocatalysis in non-aqueous medium.Within this work, reduction of ethyl-acetoacetate to ethyl-3-hydroxybutanoate has been tested with a use of baker’s yeast Saccharomyces cerevisiae as a biocatalyst in deep eutectic solvents. DES with monosaccharides (xylose, fructose and glucose) and alcohol glycerol proved to be good green solvents, while in the other tested DES obtainded small yields.
