Journal ArticleDOI
Semicontinuous production of cellulolytic enzymes with Trichoderma reesei Rutgers C30 in an aqueous two-phase system
TL;DR: Cellulolytic enzyme production was studied in an aqueous twophase system, PEG 8000 5%-Dextran 7%, with Trichoderma reesei Rutgers C30 in a 7L fermentor, and the enzyme yield was 148 FPU/g cellulose.
Journal ArticleDOI
A constitutive catabolite repression mutant of a recombinant Saccharomyces cerevisiae strain improves xylose consumption during fermentation
Vasudevan Thanvanthri Gururajan,Marie F. Gorwa-Grauslund,Bärbel Hahn-Hägerdal,Isak S. Pretorius,Isak S. Pretorius,Ricardo R. Cordero Otero +5 more
TL;DR: This study shows that a constitutive catabolite repressed mutant could be used to enhance the xylose consumption rate even in the presence of high glucose in the fermentation medium, which could help in reducing fermentation time and cost in mixed sugar fermentation.
Journal ArticleDOI
Use of In Vivo 13C Nuclear Magnetic Resonance Spectroscopy To Elucidate l-Arabinose Metabolism in Yeasts
César Fonseca,Ana Rute Neves,Alexandra M. M. Antunes,João Paulo Noronha,Bärbel Hahn-Hägerdal,Helena Santos,Isabel Spencer-Martins +6 more
TL;DR: This report provides the first experimental evidence for a link between l-arabinose metabolism in fungi and the oxidative branch of the PPP and suggests rational guidelines for the design of strategies for the production of new and efficient l-Arabinose-fermenting yeasts.
Patent
Genetically engineered yeast and mutants thereof for the efficient fermentation of lignocellulose hydrolysates
TL;DR: In this article, a mutant form of a gene encoding an aldose reductase (AR) enzyme in which only a portion of the gene is present on the vector is used as a site for homologous crossing over of vector-encoded sequences and a host cell genome.
Journal ArticleDOI
Pervaporation and ethanol upgrading — a literature review
TL;DR: In this article, the principles of pervaporation are reviewed and theories for transport mechanisms are discussed, and performances of various membrane materials are given and the utilization of pervasive water on a pilot-plant scale is exemplified.
