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, ...
Kinetics of growth and ethanol formation from a mix of glucose/xylose substrate by Kluyveromyces marxianus UFV-3
(Antonie van Leeuwenhoek, 2018)
Establishment of the optimum initial xylose concentration and nutritional supplementation of brewer`s spent grain hydrolysate for xylitol production by Candida guilliermondii
(ELSEVIER SCI LTD, 2008)
The effects of initial xylose concentration and nutritional supplementation of brewer`s spent grain hydrolysate on xylitol production by Candida guilliermondii were evaluated using experimental design methodology. The ...
Role of Glycerol Addition on Xylose-to-Xylitol Bioconversion by Candida guilliermondii
(SPRINGER, 2009)
The effect of glycerol on xylose-to-xylitol bioconversion by Candida guilliermondii was evaluated by its addition (0.7 and 6.5 g/l) to semidefined media (xylose as a substrate). The glycerol concentrations were chosen based ...
NADP+-dependent D-xylose dehydrogenase from pig liver. Purification and properties
(1990)
An NADP+-dependent D-xylose dehydrogenase from pig liver cytosol was purified about 2000-fold to apparent homogeneity with a yield of 15% and specific activity of 6 units/mg of protein. An M(r) value of 62000 was obtained ...
Engineering xylose metabolism for production of polyhydroxybutyrate in the non-model bacterium Burkholderia sacchari
(BioMed Central, 2018)
Abstract
Background
Despite its ability to grow and produce high-value molecules using renewable carbon sources, two main factors must be improved to use Burkholderia ...
Pretreatments and enzymatic hydrolysis of sugarcane bagasse aiming at the enhancement of the yield of glucose and xylose
(Departamento de Engenharia Química, 2017)
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 ...
Obtaining partial purified xylose reductase from Candida guilliermondii
(Sociedade Brasileira de Microbiologia, 2009)
The enzymatic bioconversion of xylose into xylitol by xylose reductase (XR) is an alternative for chemical and microbiological processes. The partial purified XR was obtained by using the following three procedures: an ...
Screening of bacteria to produce polyhydroxyalkanoates from xylose
(SPRINGER, 2009)
Although xylose is a major constituent of lignocellulosic feedstock and the second most abundant sugar in nature, only 22% of 3,152 screened bacterial isolates showed significant growth in xylose in 24 h. Of those 684, ...
