11. Farm to furan derivatives : Fractionation of agricultural residues and transformation of sugars to chemical building blocks
Sammanfattning : The transition of industrial production from petrochemistry to a more sustainable economy requires the use of carbon neutral, renewable feedstock, which does not compete with food and feed supplies – by-products of farming and agro-food industry offer this possibility. With a limited range of low-value applications today coupled with the need for maximal utilisation of resources, the by-products of farming can be repurposed as feedstock for biorefineries. LÄS MER
12. The role of sugar sensing and pathway selection on D-xylose utilization by Saccharomyces cerevisiae
Sammanfattning : Biorefineries have the potential to partially or entirely replace petrochemistry for the production of our daily bulk and fine chemicals. However, this replacement can only be sustainable and cost-effective if the raw material used is cheap, renewable and does not compete with the food and feed industry. LÄS MER
13. High Cell Density Strategies and Adaptive Evolution for Microbial Propionic Acid Production
Sammanfattning : Propionic acid (PA) is a naturally occurring short chain fatty acid produced by microbial fermentation of the indigestible foods in the intestine, having a positive effect on the gastrointestinal health. PA inhibits the growth of pathogenic bacteria and molds; hence it is widely used as preservative for food, feed and grains. LÄS MER
