(author)In situ phenol pertraction with 1-octanol has been experimentally studied to improve the production of the model component phenol by a recombinant strain of Pseudomonas putida S12. When the phenol concentration in the reactor reaches 2mM, the cells in fermentations without phenol removal are inhibited in growth and phenol production. Growth and...article 2011

Geers, L.F.G. (author), van de Runstraat, A. (author), Joh, R. (author), Schneider, R. (author), Goetheer, E.L.V. (author)One possible way to reduce our carbon footprint is using postcombustion capture (PCC) processes to remove CO2 from flue gases. Because of the highly dynamic characteristics of such processes, real-time performance monitoring is a very complex task. This paper presents a method for monitoring the concentrations of CO2, SOx, and a CO2 capturing...article 2011

Kimball, E. (author), Geerdink, P. (author), Goetheer, E.L.V. (author)Fixed-bed chemical looping combustion is currently being studied experimentally with the optimization of systems up to 1 kW. One of the key advantages for using the fixed-bed configuration over fluidized-beds is the flexibility in operating parameters that allows for application of CLC not only to power production, but also to niche applications...conference paper 2011

Phenol is a chemical that can be produced by a recombinant strain of the solvent tolerant bacterium Pseudomonas putida S12. However, the growth of the micro-organisms and the phenol production is inhibited at low phenol concentrations....article 2010

(author)Most fermentation products have a feedback inhibiting effect on the host organism. In situ product recovery (ISPR) can be a means to overcome this product inhibition in fermentations. Particles such as solvent impregnated resins or capsules can be valuable tools for product recovery based on extraction. To evaluate, which kind of particle will...article 2010

Goetheer, E.L.V. (author), Trap, H.C. (author), van der Gijp, S. (author)The atmospheric concentration of greenhouse gases (GHGs), e.g. CO2 methane, nitrous oxide, and chlorofluorocarbons, has increased gradually in the last century. The intergovernmental Panel on Climate Changes (IPCC) has evaluated the size and impact of this increase. One of the conclusions is that the reason behind the increased concentration of...article 2010

(author)Since the concept of solvent impregnated resins was introduced in the early 1980s, the technique has been applied to a limited amount of applications. The main disadvantage of the resins was that the amount of solvent inside was limited to approximately 1.5 ml/g polymer. A new generation of solvent impregnated resins is introduced. These...article 2009
