The isolation of pentose-assimilating yeasts and their xylose fermentation potential
(2018-01-01)
For the implementation of cellulosic ethanol technology, the maximum use of lignocellulosic materials is important to increase efficiency and to reduce costs. In this context, appropriate use of the pentose released by ...
Kinetics of growth and ethanol formation from a mix of glucose/xylose substrate by Kluyveromyces marxianus UFV-3
(Antonie van Leeuwenhoek, 2018)
Novel xylose transporter Cs4130 expands the sugar uptake repertoire in recombinantSaccharomyces cerevisiaestrains at high xylose concentrations
(Bmc, 2020-08-14)
Background The need to restructure the world's energy matrix based on fossil fuels and mitigate greenhouse gas emissions stimulated the development of new biobased technologies for renewable energy. One promising and cleaner ...
Inhibitory action of toxic compounds present in lignocellulosic hydrolysates on xylose to xylitol bioconversion by Candida guilliermondii
(SPRINGER HEIDELBERG, 2011)
The inhibitory action of acetic acid, ferulic acid, and syringaldehyde on metabolism of Candida guilliermondii yeast during xylose to xylitol bioconversion was evaluated. Assays were performed in buffered and nonbuffered ...
A strain of Meyerozyma guilliermondii isolated from sugarcane juice is able to grow and ferment pentoses in synthetic and bagasse hydrolysate media
(Springer, 2016-05-01)
The search for new microbial strains that are able to withstand inhibitors released from hemicellulosic hydrolysis and are also still able to convert sugars in ethanol/xylitol is highly desirable. A yeast strain isolated ...
Sugar cane bagasse as feedstock for second generation ethanol production: Part II: Hemicellulose hydrolysate fermentability
(Pontificia Universidad Católica de Valparaíso, 2010)
Fermentation medium and oxygen transfer conditions that maximize the xylose conversion to ethanol by Pichia stipitis
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
The xylose conversion to ethanol by Pichia stipitis was studied. In a first step, the necessity of supplementing the fermentation medium with urea. MgSO(4) x 7H(2)O, and/or yeast extract was evaluated through a 2(3) full ...
Fermentation kinetics for xylitol production by a Pichia stipitis D-Xylulokinase mutant previously grown in spent sulfite liquor
(HUMANA PRESS INC, 2008)
Spent sulfite pulping liquor (SSL) contains lignin, which is present as lignosulfonate, and hemicelluloses that are present as hydrolyzed carbohydrates. To reduce the biological oxygen demand of SSL associated with dissolved ...
High xylose yield from stem and external fraction of sugarcane biomass by diluted acid pretreatment
(2020-01-01)
Lignocellulosic materials are complex, recalcitrant, and difficult to release fermentable carbohydrates, such as xylose. Xylose is the feedstock for the development of products with high added value, such as ethanol, ...
