Xylose metabolism in the fungus Rhizopus oryzae : effect of growth and respiration on l (+)-lactic acid production

open access: yes, 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.

The Thermoanaerobacter glycobiome reveals mechanisms of pentose and hexose co-utilization in bacteria. [PDF]

open access: yesPLoS Genetics, 2011
Thermoanaerobic bacteria are of interest in cellulosic-biofuel production, due to their simultaneous pentose and hexose utilization (co-utilization) and thermophilic nature. In this study, we experimentally reconstructed the structure and dynamics of the

Biosynthesis of value-added bioproducts from hemicellulose of biomass through microbial metabolic engineering

open access: yesMetabolic Engineering Communications, 2022
Hemicellulose is the second most abundant carbohydrate in lignocellulosic biomass and has extensive applications. In conventional biomass refinery, hemicellulose is easily converted to unwanted by-products in pretreatment and therefore can't be fully ...

Xylose and Xylan Utilization by the Chick

open access: yesPoultry Science, 1977
Abstract Xylose, xylan or glucose were substituted for an equal weight of finely powdered sand in a semipurified chick diet. Xylose levels greater than 40% of the diet and a xylan level of 20% appeared to be highly toxic. Xylan yielded no useful energy to the animal; xylose yielded some energy at 20% of the diet but none at either 40 or 60%.

Quantitative metabolomics of a xylose-utilizing Saccharomyces cerevisiae strain expressing the Bacteroides thetaiotaomicron xylose isomerase on glucose and xylose

open access: yesJournal of Industrial Microbiology and Biotechnology, 2017
Abstract The yeast Saccharomyces cerevisiae cannot utilize xylose, but the introduction of a xylose isomerase that functions well in yeast will help overcome the limitations of the fungal oxido-reductive pathway. In this study, a diploid S. cerevisiae S288c[2n YMX12] strain was constructed expressing the Bacteroides thetaiotaomicron xylA

Tandem conversion xylose to 2-methylfuran with NiCu/C catalyst

open access: yesCatalysis Communications, 2023
Nowadays, 2-methylfuran is urgently needed especially in pharmaceutical manufacture. However, the direct synthesis of 2-methylfuran via the efficient dehydration and hydrogenation of xylose usually requires a multistep reaction. Herein, a route of tandem
