Enhanced xylitol production using immobilized Candida tropicalis with non-detoxified corn cob hemicellulosic hydrolysate.
This study reports an industrially applicable non-sterile xylitol fermentation process to produce xylitol from a low-cost feedstock like corn cob hydrolysate as pentose source without any detoxification. Different immobilization matrices/mediums (alginate, polyvinyl alcohol, agarose gel, polyacrylamide, gelatin, and κ-carrageenan) were studied to immobilize Candida tropicalis NCIM 3123 cells fo...
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 کاملXylitol production by Saccharomyces cerevisiae overexpressing different xylose reductases using non-detoxified hemicellulosic hydrolysate of corncob
Xylitol production was compared in fed batch fermentation by Saccharomyces cerevisiae strains overexpressing xylose reductase (XR) genes from Candida tropicalis, Pichia stipitis, Neurospora crassa, and an endogenous gene GRE3. The gene encoding a xylose specific transporter (SUT1) from P. stipitis was cloned to improve xylose transport and fed batch fermentation was used with glucose as a cosub...
متن کاملDetoxification of Corncob Acid Hydrolysate with SAA Pretreatment and Xylitol Production by Immobilized Candida tropicalis
Xylitol fermentation production from corncob acid hydrolysate has become an attractive and promising process. However, corncob acid hydrolysate cannot be directly used as fermentation substrate owing to various inhibitors. In this work, soaking in aqueous ammonia (SAA) pretreatment was employed to reduce the inhibitors in acid hydrolysate. After detoxification, the corncob acid hydrolysate was ...
