1 Xylitol yield; and 2 volumetric productivity in the first batch of fermentation by C. tropicalis immobilized on CF with and without treatment; 3 Xylitol yield and 4 volumetric productivity in the second batch of fermentation by C. tropicalis immobilized on CF with and without treatment; 5 Xylitol yield and 6 volumetric productivity in the second batch of fermentation by C. tropicalis immobilized on CF with and without treatment. Results represent the average of two independent experiments conducted with three replicates for each condition.
