Copolymeric hydrogel-based immobilization of yeast cells for continuous biotransformation of fumaric acid in a microreactor
Tadej Menegatti, Polona Žnidaršič Plazl
Izvirni znanstveni članek
Oznake: mikroreaktorji;kopolimerni hidrogeli;imobilizacija;biotransformacije;L-jabolčna kislina;microreactor;copolymeric hydrogel;immobilization;biotransformation;L-malic acid;
Although enzymatic microbioreactors have recently gained lots of attention, reports on the use of whole cells as biocatalysts in microreactors have been rather modest. In this work, an efficient microreactor with permeabilized Saccharomyces cerevisiae cells was developed and used for continuous biot ...

Hydrogel-based enzyme and cofactor co-immobilization for efficient continuous transamination in a microbioreactor
Tadej Menegatti, Polona Žnidaršič Plazl
Izvirni znanstveni članek
Oznake: koimobilizacija kofaktorja;hidrogel;mikroreaktor;amin transaminaza;kontinuirni procesi;cofactor co-immobilization;hydrogel;microreactor;amine transaminase;continuous process;
A microbioreactor was developed in which selected amine transaminase was immobilized together with the cofactor pyridoxal phosphate (PLP) to allow efficient continuous transamination. The enzyme and cofactor were retained in a porous copolymeric hydrogel matrix formed in a two-plate microreactor wit ...

Imobilizacija biokatalizatorjev v hidrogele in njihova uporaba v mikroreaktorju med dvema ploščama
Tadej Menegatti, Polona Žnidaršič Plazl
Doktorska disertacija
Oznake: biokatalizator;imobilizacija;hidrogel;mikroreaktor;
Biokataliza in kontinuirna izvedba procesov postajata ključni tehnologiji za trajnostno proizvodnjo snovi. Pri tem igrata ključno vlogo imobilizacija biokatalizatorjev, ki omogoča njihovo stabilizacijo in dolgotrajno rabo, ter uporaba pretočnih miniaturiziranih sistemov, ki vodi v intenzifikacijo pr ...

Microfluidics-based preparation and in situ immobilization of nanoscale cross-linked enzyme aggregates for continuous transamination
Tadej Menegatti, Žan Lavrič, Polona Žnidaršič Plazl
Ni določena
Oznake: amine transaminase;enzyme immobilization;cross-linked enzyme aggregates;membrane microreactor;flow biocatalysis;
A new microfluidics-based method for the generation and further continuous use of amine transaminase cross-linked enzyme aggregates (ATA-CLEAs) has been developed. The precipitation and cross-linking are carried out in separate but interconnected parts, which allows optimization of each step and thu ...

Model-based design of continuous biotransformation in a microscale bioreactor with yeast cells immobilized in a hydrogel film
Tadej Menegatti, Igor Plazl, Polona Žnidaršič Plazl
Ni določena
Oznake: microreactor;mathematical model;immobilization;whole-cell biocatalysis;continuous biotransformation;time-scale analysis;
Miniaturized flow reactors with immobilized biocatalysts offer enormous potential for process intensification. They enable long-term use of biocatalysts, continuous operation that significantly exceeds the performance of batch processes, and efficient mass and heat transfer leading to highly control ...

Tuning mechanical characteristics and permeability of polyvinyl alcohol-alginate hydrogels by natural deep eutectic solvents addition
Tadej Menegatti, Tilen Kopač, Matjaž Krajnc, Polona Žnidaršič Plazl
Ni določena
Oznake: hydrogel;natural deep eutectic solvent;polyvinyl alcohol;alginate;rheology;permeability;
Enzyme entrapment in porous hydrogel structures by cross-linking different (bio)polymers is one of the simplest and non-invasive techniques to immobilize biocatalysts. Hydrogels should provide specific attributes in order to be suitable matrices for enzyme immobilization, e.g. favorable pore size a ...

Zasnova in izdelava zaprtotočnega vetrovnika z odprto testno komoro
Blaž Menegatti, Tadej Kosel
Diplomsko delo
Oznake: diplomske naloge;zaprtotočni vetrovniki;odprte testne komore;nizke hitrosti;nizka Reynoldsova števila;zasnova kanalskega sistema;jeklene konstrukcije;testiranje aeroprofilov;testiranje propelerjev;V/STOL testiranje;
Pri testiranju aeroprofilov, propelerjev in letal z vertikalnim vzletom in pristankom dotekajoči zrak priteka na testirane objekte pod velikimi vpadnimi koti, kar privede do velikega uklona zračnega toka. Zato smo za potrebe VTOL (vertikalen vzlet in pristanek) testiranj zasnovali zaprtotočni vetrov ...
