Xylitol production and furfural consumption by a wild type Geotrichum sp

Electron. j. biotechnol; 19 (6), 2016
Background: Xylitol is a five carbons polyol with promising medical applications. It can be obtained from chemical D-xylose reduction or by microbial fermentation of Sugarcane Bagasse Hemicellulosic Hydrolysate. For this last process, some microbial inhibitors, as furfural, constitute severe bottleneck. ...

Sugarcane straw as a feedstock for xylitol production by Candida guilliermondii FTI 20037

Braz. j. microbiol; 47 (2), 2016
Abstract Sugarcane straw has become an available lignocellulosic biomass since the progressive introduction of the non-burning harvest in Brazil. Besides keeping this biomass in the field, it can be used as a feedstock in thermochemical or biochemical conversion processes. This makes feasible its incorpo...

Obtenção e cinética da xilose redutase e xilitol desidrogenase de Candida guilliermondii cultivada em hidrolisado hemicelulósico de bagaço de cana-de-açúcar

O metabolismo da D-xilose em leveduras inicia-se com a redução da D-xilose a xilitol pela xilose redutase (XR), a qual requer como cofator o NADPH e/ou NADH. O xilitol é oxidado a xilulose pela xilitol desidrogenase (XD), a qual emprega NA`D IND. +ï ou NAD`P IND. +ï como cofator. No presente trabalh...
