Journal ArticleDOI
Enzymatic conversion in aqueous two-phase systems: deacylation of benzylpenicillin to 6-aminopenicillanic acid with penicillin acylase
TL;DR: Despite the high phosphate concentration in the bottom phase the system needs to be titrated in order for the reaction to proceed, and titration of the top phase alone protected the enzyme from denaturation by strong alkali used for the titration.
Journal ArticleDOI
Xylulose fermentation by mutant and wild-type strains of Zygosaccharomyces and Saccharomyces cerevisiae.
A. Eliasson,Eckhard Boles,Björn Johansson,M Osterberg,Johan M. Thevelein,Isabel Spencer-Martins,H Juhnke,Bärbel Hahn-Hägerdal +7 more
TL;DR: In this paper, the authors compared anaerobic xylulose fermentation with wild-type strains to identify host-strain background and genetic modifications beneficial to xylose fermentation.
Journal ArticleDOI
Simultaneous enzymatic wheat starch saccharification and fermentation to lactic acid by Lactococcus lactis
TL;DR: Kinetic models, developed for the saccharification and fermentation, respectively, were used for simulation and data from SSF experiments wereUsed for model verification, and the model simulated SSF when sufficient amounts of nutrients were available during fermentation.
Journal ArticleDOI
Overproduction of pentose phosphate pathway enzymes using a new CRE–loxP expression vector for repeated genomic integration in Saccharomyces cerevisiae
TL;DR: The use of the CRE/loxP system proved to be a practical strategy to overexpress multiple genes without exhausting available markers and to be easily cured without active counter‐selection.
Journal ArticleDOI
Intracellular fluxes in a recombinant xylose-utilizing Saccharomyces cerevisiae cultivated anaerobically at different dilution rates and feed concentrations.
TL;DR: A metabolic flux model was constructed for the yeast Saccharomyces cerevisiae comprising the most important reactions during anaerobic metabolism of xylose and glucose, and showed that the flux through the reaction from ribulose 5-phosphate to xylulose5-ph phosphate was very low under all cultivation conditions.
