Biotransformation of Poly R-478 by continuous cultures of PVAL-encapsulated

Polymeric Membranes in Catalytic Reactors

“…An interesting type of entrapment of (bio)catalysts or powder-like materials in polymers was developed by the group of Vorlop. These materials consist of immobilized cells, mycelia, enzymes, ,, or catalysts, such as Pd on alumina or colloidal Pd − in polymers such as PDMS, PVA, − ,, or sulfoethyl cellulose . In the specific case of PVA, they are named “Lentikats”, as commercialised by Genialab…”

Production of Spherical Beads by JetCutting

“…In biotechnology the JetCutter was used for the preparation of immobilized (encapsulated) biocatalysts (enzymes, bacteria or fungi, [12,13]). Also in this field the independence of the fluid viscosity was proven to be advantageous since encapsulation matrices with high polymer contents and correspondingly high viscosities can be used (e.g., polyvinyl alcohol), that form mechanically very stable, abrasion-free beads [14].…”
