    • Metabolic engineering of Saccharomyces cerevisiae for ethanolic fermentation of xylose is summarized with emphasis on progress made during the last decade. Advances in xylose transport, initial xylose metabolism, selection of host strains, transformation and classical breeding techniques applied to industrial polyploid strains as well as modeling of xylose metabolism are discussed. The production and composition of the substrates--lignocellulosic hydrolysates--is briefly summarized. In a future outlook iterative strategies involving the techniques of classical breeding, quantitative physiology, proteomics, DNA micro arrays, and genetic engineering are proposed for the development of efficient xylose-fermenting recombinant strains of S. cerevisiae.

  • Bokkapitel (refereegranskat)abstract
    • In this paper, we investigate some aspects of effectiveness in two different kinds of learning environments with use of information technology. The first part shows research results related to a web-based integrated science environment (WISE) and its effects on changing the role of the teacher, the curriculum, and the student. In the second part, three different approaches for scaffolding conceptual development in physics by using interactive computer models are analysed. Research results about different aspects of their effectiveness are presented. Both parts together show empirical results in relation to different promising approaches of using information technology in science education.
