Engineering aspects of nitrification with immobilized cells
Several aspects of a nitrification process with artificially immobilized cells in an airlift loop reactor have been investigated and are described in this thesis. In chapter 1 an overview of immobilization methods, suitable reactors, modelling, small-scaleapplications and scale-up strategy is given. The subjects of chapter 1 provide the starting po...
Enzymatic synthesis of polyol seters in aqueous - organic two-phase systems
The last decade increasingly attention is paid to lipases as catalysts for synthesis of components, such as fatty acid-based surfactants, flavors, edible oil equivalents, monomers and polymers, and amides. In this thesis, the lipase-catalyzed esterification of polyols and fatty acids is described. These esters consist of a nonpolar part (fatty acid...

Enzymatic acylglycerol synthesis in membrane reactor systems
Up till twenty years ago, only chemical modifications of agricultural oils for novel uses were studied. Because of the instability of various fatty acids, enzymatic biomodifications can have advantages above the chemical route. Nowadays, enzymatic catalysis can be used for the modification of oils and fats. One way of biomodification is the enzymat...
Physical aspects of liquid-impelled loop reactors
The liquid-impelled loop reactor (LLR) is a reactor that consists of two parts : the main tube and the circulation tube. Both parts are in open connection at the bottom and at the top. The reactor is filled with a liquid phase: the continuous phase. Another liquid phase is injected in the main tube by means of pumping. This liquid phase is immiscib...
Basic bioreactor design.
Based on a graduate course in biochemical engineering, provides the basic knowledge needed for the efficient design of bioreactors and the relevant principles and data for practical process engineering, with an emphasis on enzyme reactors and aerated reactors for microorganisms. Includes exercises.
Modelling and characterization of an airlift-loop bioreactor
An airlift-loop reactor is a bioreactor for aerobic biotechnological processes. The special feature of the ALR is the recirculation of the liquid through a downcomer connecting the top and the bottom of the main bubbling section. Due to the high circulation-flow rate, efficient mixing and oxygen transfer is combined with a controlled liquid flow in...
Design of an organic-liquid-phase / immobilized-cell reactor for the microbial epoxidation of propene
Replacement of a considerable part of the traditional, aqueous reaction medium in biotechnology by an organic medium is a promising technique to broaden the scope and range of biotechnological processes. This seems especially to be true for the conversion of non-polar substances. The high capacity of solvents for sparingly water-soluble substrates ...
