One major challenge in the bioconversion of lignocelluloses into ethanol is to develop Saccharomyces cerevisiae strains that can utilize all available sugars in biomass hydrolysates, especially the d‐xylose and l‐arabinose that cannot be fermented by the

The role of arabinokinase in arabinose toxicity in plants
The Plant Journal, 2016SummaryPlant cell wall polymers are synthesized by glycosyltransferases using nucleotide sugars as substrates. Most UDP‐sugars are synthesized from UDP‐glucose via de novo pathways but salvage pathways work in parallel to recycle sugars, which have been released during cell wall polymer and glycoprotein turnover.

Publisher Summary This chapter discusses the determination of L-arabinose isomerase. L-arabinose isomerase activity is assayed spectrophotometrically at 30° using a standard spectrophotometer equipped with an absorbancy converter, automatic cuvette positioner, and recorder.

Screening for L-Arabinose Fermenting Yeasts
1996Utilization of pentose sugars (D-xylose and L-arabinose) derived from hemicellulose is essential for the economic conversion of biomass to ethanol. Xylose-fermenting yeasts were discovered in the 1980s, but to date, no yeasts have been found that ferment L-arabinose to ethanol in significant quantities.

The pathway of L-arabinose degradation was studied in the haloarchaeon Haloferax volcanii. It is shown that L-arabinose is oxidatively degraded to α-ketoglutarate. During growth on L-arabinose, L-arabinose dehydrogenase (L-AraDH) was induced. The enzyme was purified as a 130 kDa homotetrameric protein catalyzing the oxidation of L-arabinose with both ...

Publisher Summary This chapter discusses the determination of D-arabinose isomerase. Two assay methods may be employed. The first utilizes the cysteine–carbazole test for ketopentoses to determine the quantity of D-ribulose formed after incubation of D-arabinose and enzyme.
