1. Ethanol production from lignocellulose using high local cell density yeast cultures. Investigations of flocculating and encapsulated Saccharomyces cerevisiae
Sammanfattning : Efforts are made to change from 1st to 2nd generation bioethanol production, using lignocellulosics as raw materials rather than using raw materials that alternatively can be used as food sources. An issue with lignocellulosics is that a harsh pretreatment step is required in the process of converting them into fermentable sugars. LÄS MER
2. Bioreduction of Carbonyl Compounds to Chiral Alcohols by Whole Yeast Cells: Process Optimisation, Strain Design and Non-Conventional Yeast Screening
Sammanfattning : Chiral building blocks are needed for the production of drugs and fine chemicals, which requires the use of several synthetic routes to produce a specific enantiomer of interest. One promising approach to introduce chirality into molecules is the stereo-selective whole cell bioreduction of carbonyl compounds or ketones to the corresponding chiral alcohols. LÄS MER
Sammanfattning : Chiral building blocks are needed in the chemical and pharmaceutical industries for the production of fine chemicals and pharmaceuticals. The utilisation of microorganisms and enzymes to perform stereoselective reductions of carbonyl compounds is an efficient and widely applied method for the generation of chiral molecules. LÄS MER
Sammanfattning : Saccharomyces cerevisiae has immense potential as a cell factory in various biotechnological processes where biomass from agricultural industry residues is used as feedstock. Nonetheless, the inhibitors released during the pretreatment of the biomass makes lignocellulosic hydrolysates a challenging substrate for microorganisms. LÄS MER
5. Metabolic Engineering of Xylose-Utilising Saccharomyces cerevisiae Strains. A Closer Look at Recombinant Strains Based on the Xylose Reductase-Xylitol Dehydrogenase Pathway
Sammanfattning : Saccharomyces cerevisiae produces ethanol efficiently from the hexose sugars in lignocellulose hydrolysates, but it can not utilise pentose sugars such as xylose and arabinose. Stable xylose-utilising S. LÄS MER
