Fig. 1 – Profiles of xylose (square), xylitol (circle) and cell biomass (triangle) in batch fermentation with C. guilliermondii FTI
20037 in sugarcane straw hemicellulosic hydrolyzate with different nutritional supplementation and the two conditions of
initial oxygen availability: (A) without supplementation (H1); (B) supplementation with (NH4)2SO4 (H2); (C) full
supplementation with (NH4)2SO4, rice bran extract and CaCl2·2H2O (H3). Dashed line (- - -) and open style: increased initial
oxygen availability (25mL of fermentation medium). Solid line (—) and solid style: Reduced initial oxygen availability (50mL
of fermentation medium).
