We performed fed-batch fermentations of glucose and xylose mixtures producing butanol. Our aim was to develop a feeding strategy for coping with carbon catabolite repression (CCR) and sequential utilization problems as well as understanding the effec

To our knowledge, this is the first growth model of Clostridium beijerinckii NCIMB 8052 on glucose and xylose as representative lignocellulosic sugars, which considers the synergistic effects of sugars on the growth rate. We fitted models with differ

We applied response surface methodology to understand the effect and extend of carbon catabolite repression (CCR) on growth of Clostridium beijerinckii NCIMB 8052 using xylose and glucose as representative lignocellulosic sugars. We performed batch g

Models are the starting point for any computation-based engineering activity and thus errors in the construction - instantiation - coding of models are beyond the most expensive ones. Any improvement of this situation requires a systematic approach t

Interdisciplinary computational engineering work implies the use of different programs taken from different disciplines and performing a series of concerted computations. The user is thereby faced with the task to bring together different code that h

In any plant, it is the pressure that drives convective flow of mass from one part to another. A systematic method of modelling the flow and the pressure distribution is derived based on a finite-volume approached captured in a graph. This approach i

The dynamical modelling of physical (bio-)chemical processes based on first principles considerations is analysed from a structural point of view. Based on a classification of the variables and equations that occur in such models, we propose a genera

The paper introduces a general framework for the modelling of controlled physical processes. It is shown that this framework enables a systematic and thorough analysis of the model veiy early in the model design process. It also provides an appropria
