1. On-line Monitoring Techniques for the Study of Yeast Physiology. Some Studies on the Yeasts Pichia stipitis and Saccharomyces cerevisiae
Abstract : On-line monitoring techniques have been used with the goal of optimizing fermentation processes involving the yeasts Saccharomyces cerevisiae (Baker's yeast) and Pichia stipitis (a xylose fermenting yeast), and a highly equipped fermentor system has been developed for these studies. The fed-batch growth of S. READ MORE

2. The effects of extramural language : Relationships between engagement in Japanese language activities and general Japanese language proficiency
Abstract : Many L2 learners believe they learn their target language by using it extramurally, i.e. outside the classroom. This topic, language learning as a result of engagement in L2 use, has garnered increased attention in the last decade. READ MORE

3. 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

4. Impact of glucose feed rate on productivity and recombinant protein quality in Escherichia coli
Abstract : The goal of this work was to contribute to the fed-batch process optimisation task by deriving parameters that have considerable impact on productivity as well as product quality The chosen parameters were I) the design of the glucose feed profile, II) the choice of induction strategy, with respect to the method of addition, and III) the time of the induction, with respect to the specific glucose consumption rate.The present fed-batch experiments using the lacUV5-promoter, for production of b-galactosidase, have shown that a high glucose feed rate gives a specific production rate, qp, that is twice as high, after induction, compared to a feed rate that is 2.
