文摘

Xylose-glucose separation is improved by converting glucose into gluconic acid. Oxygen required for glucose oxidase catalysis is provided by catalase catalysis. Biocatalytic productivity of coupled reactions is dependent on oxygen availability. Free enzyme system is compared to three enzyme immobilization systems. Fouling-induced enzyme immobilization enables high enzyme loadings.
