11. Use of feruloyl esterases for chemoenzymatic synthesis of bioactive compounds
Abstract : Feruloyl esterases (FAEs, EC 3.1.1.73) represent a subclass of carboxylic acid esterases that under normal conditions catalyze the hydrolysis of the ester bond between hydroxycinnamic acids (ferulic acid, sinapic acid, caffeic acid, p-coumaric acid) and arabinose residues in plant cell walls.

12. Downstream Processing Using Membrane Technology
Abstract : Membrane filtration is a very gentle separation technique and can be used at low temperatures. This makes it suitable for liquids that contain micro-organisms and/or are heat sensitive, which is often the case in liquids processed in the field of biotechnology. READ MORE

13. Grey-box Identification of Distributed Parameter Systems
Abstract : This thesis considers the problem of making dynamic models for industrial processes by combining physical modelling with experimental data. The focus is on distributed parameter systems, that is, systems for which the model structure involves partial differential equations (PDE). Distributed parameter systems are important in many applications, e. READ MORE

14. Multivariate monitoring, modelling and control for stabilization of bioprocesses
Abstract : The obstacles to overcome low reproducibility and stability of bioprocesses are numerous. Underlying biochemical processes are inherently non-linear, complex and subject to shifting initial conditions. Problems with high variability are also associated to production strains and scale-up of a bioprocess to largescale bioreactors. READ MORE

15. Physiological and biochemical aspects of vegetable processing. A case study on carrots
Abstract : The aim of the present study was to enhance our understanding of vegetables as living organisms, interacting dynamically with the environment, and to explore the possible influence of metabolic changes on subsequent processing operations. Growing conditions, harvesting and handling in the packing house and storage conditions are key events leading to a defined “physiological status” of the vegetable that is going to be consumed as a fresh product or a processed product.
