An optimization of esters synthesis catalysed by Mucor javanicus T45 lipase in non-water media
Languages of publication
An optimization of enzymatic synthesis of esters in nonwater environment was performedby mens of a gradient method.The studies were aimed at obtaining a model synthesis of butyl oleate catalyzed by Mucor javanicus T45 lipase.Theoptimized, changed parameters were as follows:substrated mass, lipase mass and chemical activator mass (diethanoloamine) which profitably modified the essential water layer of the lipase.For the initial concentration of the substrates equal to 57-67%, in reaction environment the obtained yield of coversion of oleic acid was in the range of 90-95%. A transfer of optimized conditions of butyl oleate synthesis onto oleates of the other aliphatic alcohols, enabled elaboration of simple in performance methods of synthesisof a broad variety of esters of oleic acid and aliphatic alcohols (C2-C18).
