Membrane reactors could serve as a tool for enzyme-catalyzed reactions and they enable the performance of catalytic reaction, enzyme recovery and product isolation as a one-step process. In the presented work, the use of continuous flat-shape and continuous tubular membrane enzymatic reactors for di

Starch hydrolysates were prepared by enzymatic hydrolysis with a -amylase and mixture of glucoamylase and pullulanase. Additionally the so-called filtration enzyme action (lysophospholipase) was introduced for starch hydrolysates production. Enzymatic hydrolysates were purified on filtration unit (A

The concentration of bergamot peel oils by pervaporation, with and without enzymatic pre-treatment, is studied. The influence of different PV membranes, industrial enzymes and operational parameters on the PV process are also investigated. GC-MS analyses are carried out to evaluate the recovery of t

This paper presents a study of enzymatic esterification of oleic-acid and i-amyl alcohol. The product of this reaction, i-amyl-oleate, is widely used as a bio-lubricant. During the esterification reaction, water is produced as a by-product, which has a disadvantageous effect on the reaction rate and

In this paper, hydrogel membrane techniques used for CO2 removal from air were introduced. Firstly, the PVDF hollow fibers were prepared by dry-jet wet-spinning phase-inversion process, then membrane module was made of them as a CO2 removal equipment. PVDF hollow fiber membranes modified by alkali,
