Biokatalitski procesi v pretočnih sistemih

Modic, Vid (author), Žnidaršič Plazl, Polona (mentor)

Biokataliza je proces pri katerem se za kemijsko pretvorbo snovi uporabljajo biokatalizatorji, ki so lahko kot encimi, izolirani iz celic, grobi encimski pripravki ali celotne celice. Potrebe industrije po zeleni proizvodnji, čistejših produktih in trajnostem razvoju, so pripeljale do izboljševanja klasičnih procesov ter postavile nove trende za kemično proizvodnjo. Prenos biokatalitskih procesov v kontinuirno obratovanje prinaša številne prednosti pred proizvodnjo v klasičnih šaržno obratujočih sistemih. Z razvojem novih, boljših in cenejših imobilizacijskih tehnik biokatalizatorjev se pričakuje vedno večja uporaba takšnih sistemov v industrijskem merilu. Biokatalitske procese lahko izvajamo v različnih tipih reaktorjev. Izbor reaktorja je odvisen od uporabljenega biokatalizatorja, imobilizacijske tehnike ter reakcijskih parametrov. Pričujoče delo obravnava reaktorje za kontinuirno izvedbo biokatalitskih procesov, pregled imobilizacijskih tehnik ter izbrane primere biokatalitskih procesov v pretočnih sistemih.

Abstract

Biocatalysis is a process in which biocatalysts are used to achieve chemical conversion of a substance. For this, enzymes isolated from cells, crude enzyme extracts or whole cells are used. Industry needs for green production, cleaner products and sustainable development have led to the improvement of classic processes and set new trends for chemical production. The transfer of biocatalytic processes to continuous operation brings many advantages over the production in classic batch systems. With the development of new, better and cheaper immobilization techniques of biocatalysts, it is expected that the use of such systems on an industrial scale will increase. Biocatalytic processes are carried out in different types of reactors. The choice of reactor depends on the used biocatalyst, the immobilization technique, and the reaction parameters. The literature refers to continuously operating types of reactors most suited for performing biocatalytic processes, immobilization techniques, and selected examples of biocatalytic processes in continuous systems.
