LITERATURE
synthesis
expression of gene xylB in Saccharomyces cerevisiae results in production of 17 g D-xylonate/l at 0.23g/l/h from 23 g D-xylose/l. D-Xylonate accumulates intracellularly to 70 mg/g, xylitol to 18 mg/g. Cells expressing D-xylonolactone lactonase xylC from Caulobacter crescentus with xylB initially produce more extracellular D-xylonate than cells lacking xylC at both pH5.5 and pH3, and sustain higher production at pH3. Cell vitality and viability decreases during D-xylonate production at pH 3.0
