Effects of environmental conditions on production of xylitol byCandida boidinii.
Candida boidinii NRRL Y-17213 produced more xylitol thanC. magnolia (NRRL Y-4226 and NRRL Y-7621),Debaryomyces hansenii (C-98 M-21, C-56 M-9 and NRRL Y-7425), orPichia (Hansenula) anomala (NRRL Y-366). WithC. boidinii, highest xylitol productivity was at pH 7 but highest yield was at pH 8, using 5 g urea and 5 g Casamino acids/I. Decreasing the aeration rate decreased xylose consumption and cel...
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...
متن کاملIntegrated Process of Arabinose Biopurification and Xylitol Fermentation Based on the Diverse Action of Candida boidinii
Agricultural and agro-industrial residues (agro-residues) containing high amounts of carbohydrates, such as cellulose and hemicellulose, are produced in large amounts annually worldwide.1,2 Agro-residues are attractive raw materials of biorefinery processes producing value-added products due to their relatively low commercial value, renewability and abundant availability.3 Biorefining of agro-r...
متن کاملXylitol Formation and Key Enzyme Activities in Candida boidinii under Different Oxygen Transfer Rates
Under oxygen transfer rates (OTR), from 10 to 30 mmol. l –1 h , Candida boidinii NRRL Y-17213 exhibited both NADH and NADPH linked D-xylose reductase activities with the former being higher. Xylitol dehydrogenase was mainly NAD dependent. Maximum xylitol production was attained at OTR of 14 mmol. l h . Ethanol, glycerol and ribitol were also produced. A correlation between xylitol accumulation,...
متن کاملMicrowave Assisted Extraction of Olive Oil Pomace by Acidic Hexane
In this study, Microwave-Assisted Solvent Extraction (MASE) was used to recover oil residues from pomace olive using acidic hexane. Results obtained demonstrated that oil extraction yield increased with time, the amount of acetic acid in hexane and power radiation. For both radiation powers used (170 and 510W), the optimal extraction time and most interesting content of acetic acid in hexan...
