Positive selection of efficient ethanol producers from xylose at 45 °C in the yeast Ogataea polymorpha [PDF]
Scientific ReportsThis research presents a method for the positive selection of mutants with improved xylose and L-arabinose fermentation in the thermotolerant, naturally xylose-utilizing yeast Ogataea polymorpha which is based on isolation of the mutants growing on L ...

Disrupting ribulose-5-phosphate metabolic flux enhances riboflavin production in Escherichia coli BL21(DE3). [PDF]
PLoS ONERiboflavin (vitamin B2) is an essential water-soluble vitamin. To increase its production in a previously engineered strain, R203, we employed metabolic engineering strategies to improve the supply of ribulose-5-phosphate, a key precursor.

Structural Study of L-Arabinose Isomerase from Latilactobacillus sakei
CrystalsD-Tagatose is a rare sugar of interest as a low-calorie sweetener, and enzymatic isomerization of D-galactose is a practical production route. L-arabinose isomerase (L-AI; EC 5.3.1.4) is a promising catalyst for the above process, but many characterized ...

Pentose metabolism in Mycobacterium smegmatis: comparison of L-arabinose isomerases induced by L-arabinose and D-galactose [PDF]
Journal of Bacteriology, 1978 D-Galactose, which did not serve as a growth substrate, was found to induce an L-arabinose isomerase of similar properties to the L-arabinose-induced L-arabinose isomerase. In both cases the pH profiles, pH stability, optimum temperature, heat stability, substrate specificity, metal ion requirements, mobility on polyacrylamide gel electrophoresis, and ...
