Genomic and transcriptomic analysis of Candida intermedia reveals the genetic determinants for its xylose-converting capacity

Biotechnology for Biofuels, 2020
Background An economically viable production of biofuels and biochemicals from lignocellulose requires microorganisms that can readily convert both the cellulosic and hemicellulosic fractions into product.

Proteomic analysis of the secretory response of Aspergillus niger to D-maltose and D-xylose [PDF]

, 2011
Fungi utilize polysaccharide substrates through extracellular digestion catalyzed by secreted enzymes. Thus far, protein secretion by the filamentous fungus Aspergillus niger has mainly been studied at the level of individual proteins and by genome and ...

Comparative xylose metabolism among the Ascomycetes C. albicans, S. stipitis and S. cerevisiae.

PLoS ONE, 2013
The ascomycetes Candida albicans, Saccharomyces cerevisiae and Scheffersomyces stipitis metabolize the pentose sugar xylose very differently. S. cerevisiae fails to grow on xylose, while C. albicans can grow, and S.

Identification of genes involved in xylose metabolism of Meyerozyma guilliermondii and their genetic engineering for increased xylitol production

AMB Express, 2020
Meyerozyma guilliermondii, a non-conventional yeast that naturally assimilates xylose, is considered as a candidate for biotechnological production of the sugar alternative xylitol. Because the genes of the xylose metabolism were yet unknown, all efforts

Cross-reactions between engineered xylose and galactose pathways in recombinant Saccharomyces cerevisiae

Biotechnology for Biofuels, 2010
Background Overexpression of the PGM2 gene encoding phosphoglucomutase (Pgm2p) has been shown to improve galactose utilization both under aerobic and under anaerobic conditions.

Obtaining partial purified xylose reductase from Candida guilliermondii [PDF]

Brazilian Journal of Microbiology, 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 agarose column, a membrane reactor or an Amicon Ultra-15 50K Centrifugal Filter device at yields of 40%, 7% and 67%, respectively.
