Resumo: Sugar cane bagasse hemicellulosic fraction was hydrolyzed by treatment with 100 mg of sulfuric acid per gram of dry mass at 140 °C for 20 min. The hydrolyzate was used as the substrate to grow Candida tropicalis IZ 1824 in a 1.0-1 bioreactor at 30 °C; aeration at 1.0 and 2.0 vvm; stirring at 400 rpm and initial pH of 6.0. The kinetic parameters, calculated for both cultivations—at 1.0 and 2.0 wm—included: maximum growth rate (μmax) of 0.057 h−1 and 0.137 h−1, yield of 0.30 and 0.31 g/g and productivity (Qx) of 0.196 g/l per h and 0.202 g/l per h, respectively. The protein produced (31.3% of the total biomass) contains essential amino acids for animal feed.
