Abstract

Organska topila so odgovorna za velik del odpadkov kemijskih proizvodenj in s tem posledično za onesnaževanje. Z uporabo nekonvencionalnih topil, med katere sodijo ionske kapljevine in evtektična topila, ter z uporabo okolju prijaznih bioloških katalizatorjev lahko bistveno zmanjšamo vpliv industrijske proizvodnje na okolje. Zelena topila lahko uporabljamo v široki paleti aplikacij, vključno z encimskimi biotransformacijami. Ionske kapljevine so poleg tega zanimive tudi zaradi izjemno velikega števila možnih spojin, kar nam ponuja možnost priprave topil za specifične namene. Prav tako nam to omogoča, da jih spremenimo do te mere, da omogočajo celo izvedbo nekaterih biokatalitskih reakcijah, ki jih s tradicionalnimi topili ni mogoče izvesti. Za številne encime je mogoče ugotoviti, da so ob uporabi ustrezne ionske kapljevine oz. evtektičnega topila bolj aktivni kot v konvencionalnih topilih, pogosto pa so tudi bolj temperaturno obstojni.

Secondary title: Ionic liquids and deep eutectic solvents application in biotransformations
Secondary abstract: Organic solvents are responsible for the majority of wastes created by chemical production facilities and thus for environmental pollution. With the use of nonconventional solvents comprising ionic liquids and deep eutectic solvents and by using environment-friendly biological catalysts we can significantly lower the influence of industrial production on the environment. Green solvents can be used in a wide range of applications, including enzymatic biotransformations. Ionic liquids are also interesting due to a large number of possible compounds, which offers us the possibility to tailor solvents for the specific need. That property allows us to change them to the extent that they enable us to perform even biocatalytic reactions, which are not possible by the use of traditional organic solvents. For many enzymes, it is evident that the use of appropriate ionic liquid or deep eutectic solvent instead of conventional solvents results in increased activity and often also in improved temperature stability.
