Efficient hydrogen production from the lignocellulosic energy crop Miscanthus by the extreme thermophilic bacteria Caldicellulosiruptor saccharolyticus and Thermotoga neapolitana [PDF]

, 2009
Background The production of hydrogen from biomass by fermentation is one of the routes that can contribute to a future sustainable hydrogen economy. Lignocellulosic biomass is an attractive feedstock because of its abundance, low production costs and ...

Utilization of Glucose and Xylose in Ruminal Strains of Butyrivibrio fibrisolvens [PDF]

Applied and Environmental Microbiology, 1994
The dual-substrate utilization pattern in cultures of five ruminal strains of Butyrivibrio fibrisolvens growing on glucose and xylose was investigated. Strains ATCC 19171 and 86 utilized glucose and xylose simultaneously. Other strains exhibited diauxic growth. Strains X1 and CE 51 exhibited classical diauxic growth

Overexpression of Transketolase Relieves xylA Repression and Enhances Xylose Utilization in Saccharomyces cerevisiae During Mixed Sugar Fermentation

GCB Bioenergy
Metabolic engineering of Saccharomyces cerevisiae has enabled xylose‐fermenting yeast strains. However, the bioavailability dilemma of xylose has become the core bottleneck restricting the economy of lignocellulose.

Engineering mixed sugar metabolic channels in Pseudomonas putida to produce vanillic acid

Synthetic and Systems Biotechnology
Hydrolysis of lignocellulosic biomass produces the mixed sugars of glucose (60–70 %), xylose (20–30 %), and arabinose (2–20 %), etc. Using mixed sugars instead of pure glucose for microbial biosynthesis will reduce the cost of carbon source and maximize ...

The Effect of Feeding Strategy on Butanol Production by Clostridium beijerinckii NCIMB 8052 using Glucose and Xylose

Chemical Engineering Transactions, 2018
We performed fed-batch fermentations of glucose and xylose mixtures producing butanol. Our aim was to develop a feeding strategy for coping with carbon catabolite repression (CCR) and sequential utilization problems as well as understanding the effect of
