Metabolism of Toxic Sugars by Strains of the Bee Gut Symbiont Gilliamella apicola. [PDF]

, 2016
Social bees collect carbohydrate-rich food to support their colonies, and yet, certain carbohydrates present in their diet or produced through the breakdown of pollen are toxic to bees.

Arthrobacter d-xylose isomerase: partial proteolysis with thermolysin [PDF]

Biochemical Journal, 1993
The pattern and kinetics of partial proteolysis of Arthrobacter D-xylose isomerase tetramer was studied in order to determine the flexibility of surface loops that may control its stability. It was completely resistant to trypsin, chymotrypsin and elastase at 37 degrees C, but thermolysin cleaved specifically and quantitatively at Thr-347-Leu-348 ...

Systematic optimization of gene expression of pentose phosphate pathway enhances ethanol production from a glucose/xylose mixed medium in a recombinant Saccharomyces cerevisiae

AMB Express, 2018
The pentose phosphate pathway (PPP) plays an important role in the synthesis of ribonucleotides and aromatic amino acids. During bioethanol production from cellulosic biomass composed mainly of d-glucose and d-xylose, the PPP is also involved in xylose ...

Enhanced whole genome sequence and annotation of Clostridium stercorarium DSM8532T using RNA-seq transcriptomics and high-throughput proteomics [PDF]

, 2014
BACKGROUND: Growing interest in cellulolytic clostridia with potential for consolidated biofuels production is mitigated by low conversion of raw substrates to desired end products.

Reconstruction of xylose utilization pathway and regulons in Firmicutes

BMC Genomics, 2010
Background Many Firmicutes bacteria, including solvent-producing clostridia such as Clostridium acetobutylicum, are able to utilize xylose, an abundant carbon source in nature.

Comparison of xylose fermentation by two high-performance engineered strains of Saccharomyces cerevisiae

Biotechnology Reports, 2016
Economical biofuel production from plant biomass requires the conversion of both cellulose and hemicellulose in the plant cell wall. The best industrial fermentation organism, the yeast Saccharomyces cerevisiae, has been developed to utilize xylose by ...

Directed enzyme evolution: climbing fitness peaks one amino acid at a time [PDF]

, 2009
Directed evolution can generate a remarkable range of new enzyme properties. Alternate substrate specificities and reaction selectivities are readily accessible in enzymes from families that are naturally functionally diverse.

d-xylose accelerated death of pentose metabolizing Saccharomyces cerevisiae

Biotechnology for Biofuels and Bioproducts, 2023
Rapid and effective consumption of d-xylose by Saccharomyces cerevisiae is essential for cost-efficient cellulosic bioethanol production. Hence, heterologous d-xylose metabolic pathways have been introduced into S. cerevisiae.

The power of many: when genetics met yeasts and high‐throughput

Biological Reviews, EarlyView.
ABSTRACT In recent years, complex technological capabilities have evolved, driven by the need to solve complex and integrative biological questions through global analyses. New equipment allows the scaling up and automation of processes which previously were carried out on a very limited scale.
