متن کاملMicrobial production of xylitol from L-arabinose by metabolically engineered Escherichia coli.
An Escherichia coli strain, ZUC99(pATX210), which can produce xylitol from L-arabinose at a high yield, has been created by introducing a new bioconversion pathway into the cells. This pathway consists of three enzymes: L-arabinose isomerase (which converts L-arabinose to L-ribulose), D-psicose 3-epimerase (which converts L-ribulose to L-xylulose), and L-xylulose reductase (which converts L-xyl...
متن کاملCloning of the Xylitol Dehydrogenase Gene from Glticonobacter oxydans and Improved Production of Xylitol from D
sequence suggested that the enzyme belongs to the short-chain dehydrogenase!reductase family. Expression plasmids for the xith gene were constructed and used to produce recombinant strains of G. orvdans that had up to 11-fold greater XDH actiyity than the wildtype strain. When used in the pToduction of xylitol from D-arabitol under controlled aeration and pH conditions, the strain harboring the...
متن کاملProduction of xylitol by yeasts
Xylitol is a naturally occuring sugar alcohol, which is currently produced chemically on a large scale. In recent years the bioconversion of D-xylose from lignocellulosic residues into xylitol, gained an increased attention as an alternative procedure , due to its high efficiency and reduced cost of such technology. The biotechnological method of producing xylitol involves microorganisms that a...
متن کاملProduction of xylitol from D-xylose by a xylitol dehydrogenase gene-disrupted mutant of Candida tropicalis.
Xylitol dehydrogenase (XDH) is one of the key enzymes in d-xylose metabolism, catalyzing the oxidation of xylitol to d-xylulose. Two copies of the XYL2 gene encoding XDH in the diploid yeast Candida tropicalis were sequentially disrupted using the Ura-blasting method. The XYL2-disrupted mutant, BSXDH-3, did not grow on a minimal medium containing d-xylose as a sole carbon source. An enzyme assa...
