Xylose metabolism in the fungus Rhizopus oryzae : effect of growth and respiration on l (+)-lactic acid production [PDF]
, 2008 The fungus Rhizopus oryzae converts both glucose and xylose under aerobic conditions into chirally pure l(+)-lactic acid with by-products such as xylitol, glycerol, ethanol, carbon dioxide and fungal biomass.

Balance of XYL1 and XYL2 expression in different yeast chassis for improved xylose fermentation
Frontiers in Microbiology, 2012 Reducing xylitol formation is an important step in engineering xylose reductase/xylitol dehydrogenase pathway for ethanol production from xylose in Saccharomyces cerevisiae. In this study, to balance the expression of XYL1 and mutant XYL2 encoding xylose

Cloning of the Xylose Reductase Gene of Candida milleri
Journal of Microbiology and Biotechnology, 2013 The entire nucleotide sequence of the xylose reductase (XR) gene in Candida milleri CBS8195 sourdough yeast was determined by degenerate polymerase chain reaction (PCR) and genome walking. The sequence analysis revealed an open-reading frame of 981 bp that encoded 326 amino acids with a predicted molecular mass of 36.7 kDa.

Journal of Industrial Microbiology & Biotechnology, 2011 Kluyveromyces marxianus is thermotolerant yeast that is able to utilize a wider range of substrates and has greater thermal tolerance than most other yeast species. K. marxianus can assimilate xylose, but its ability to produce ethanol from xylose in oxygen-limited environments is poor. In the present study, the K.

Optimization of CDT-1 and XYL1 expression for balanced co-production of ethanol and xylitol from cellobiose and xylose by engineered Saccharomyces cerevisiae. [PDF]
PLoS ONE, 2013 Production of ethanol and xylitol from lignocellulosic hydrolysates is an alternative to the traditional production of ethanol in utilizing biomass. However, the conversion efficiency of xylose to xylitol is restricted by glucose repression, causing a ...
