Production 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...
متن کاملXylitol Production from Corn Cobs Hemicellulosic Hydrolysate by Candida tropicalis Immobilized Cells in Hydrogel Copolymer Carrier
The ability of five yeast strains (locally isolated) to ferment xylose to xylitol were screened using a corn cobs hydrolysate. Candida tropicalis proved to be the best producer. The effects of culture conditions, namely initial pH, nitrogen source and yeast extract concentration on xylitol production were evaluated. The conditions for batch production of xylitol, using C. tropicalis immobilized...
متن کاملEnhanced Xylitol Production from Statistically Optimized Fermentation of Cotton Stalk Hydrolysate by Immobilized Candida tropicalis
Cotton (Gossypium hirsutum), which is one of the most abundant crops in the world, is cultivated widely in China, the United States, and Central Asia. The cotton stalk generated with cotton cultivation is an important source of lignocellulosic biomass. In recent years, cotton stalk has received increasing attention from researchers engaged in bioconversion areas, and some high-value products, s...
متن کاملEvaluation of Fermentation Conditions by Candida tropicalis for Xylitol Production from Sago Trunk Cortex
Xylitol production from sago trunk cortex hydrolysate using Candida tropicalis was evaluated in shake flasks and a bioreactor. The fermentation and kinetic behaviours of this microorganism were investigated using sago trunk cortex hydrolysate and commercial xylose as substrate. Results obtained for sago trunk hydrolysate were close to the commercial xylose with xylitol yield of 0.82 gg -1 and p...
متن کاملEvaluation of some lignocellulosic byproducts of food industry for microbial xylitol production by Candida tropicalis
Some lignocellulosic food byproducts such as potato peels, wheat bran, barley bran and chestnut shells were evaluated as potential sources of xylose for microbial xylitol production by yeasts. Potential yeast strains were selected after screening xylitol production of some indigenous yeasts in a defined fermentation medium. Candida tropicalis strains gave the highest results with 83.28 and 54.0...
