Journal ArticleDOI
The xylose reductase/xylitol dehydrogenase/xylulokinase ratio affects product formation in recombinant xylose-utilising Saccharomyces cerevisiae
Anna Eliasson,Anna Eliasson,Jan-Hendrik S. Hofmeyr,Scott Pedler,Scott Pedler,Bärbel Hahn-Hägerdal +5 more
TL;DR: Overexpression of XK was found to be necessary for ethanol formation from xylose, and TMB 3004, which was the strain with a XR/XDH/XK ratio corresponding to the theoretical optimal ratio, fermented xyloses to ethanol most efficiently.
Journal ArticleDOI
Effect of enhanced xylose reductase activity on xylose consumption and product distribution in xylose-fermenting recombinant Saccharomyces cerevisiae.
Marie Jeppsson,Karin Träff,Björn Johansson,Bärbel Hahn-Hägerdal,Marie-Francoise Gorwa-Grauslund +4 more
TL;DR: The xylose reductase (XR) activity was increased 4-19 times in both TMB3001 and the ZWF1-disrupted strain TMB3255, and the increase in XR activity fully restored the xylOSE consumption rate.
Journal ArticleDOI
Ethanolic fermentation of pentoses in lignocellulose hydrolysates.
TL;DR: Different strategies involving strain adaptation, and protein and genetic engineering adopted to overcome different obstacles in the fermentation of lignocellulose hydrolysate, are discussed.
Journal ArticleDOI
Enhanced sensitivity in PCR detection of Listeria monocytogenes in soft cheese through use of an aqueous two-phase system as a sample preparation method.
TL;DR: The results suggest that the improved detection sensitivity following partitioning of the cheese homogenate in an aqueous two-phase system may be due to partitioned of the PCR inhibitors to the polyethylene glycol phase.
Journal ArticleDOI
Reagentless chemically modified carbon paste electrode based on a phenothiazine polymer derivative and yeast alcohol dehydrogenase for the analysis of ethanol
Elena Domínguez,H.L. Lan,Yoshi Okamoto,P.D. Hale,Terje Skotheim,Lo Gorton,Bärbel Hahn-Hägerdal +6 more
TL;DR: In this paper, an amperometric biosensors for ethanol were constructed by immobilizing yeast alcohol dehydrogenase (ADH) on carbon paste (graphite powder: paraffin oil) chemically modified with a polymer to which a necessary mediator for electrocatalytic NADH oxidation had been covalently attached.
