Candida guilliermondii cells were immobilized in Ca-alginate beads and used for xylitol production from concentrated sugarcane bagasse hydrolysate during five successive fermentation batches, each lasting 48 hours. The bioconversion efficiency of 53.2%, the productivity of 0.50 g/l x h and the final xylitol concentration of 23.8 g/l obtained in the first batch increased to 61.5%, 0.59 g/l x h and 28.4 g/l, respectively, in the other four batches (mean values), with variation coefficients of up to 2.3%.
季也蒙念珠菌细胞被固定在海藻酸钙珠中，并用于在连续五个发酵批次中从浓缩甘蔗渣水解物生产木糖醇，每个批次持续48小时。第一批获得的生物转化效率为53.2%，生产率为0.50 g/l·h，最终木糖醇浓度为23.8 g/l，在其他四个批次（平均值）中分别提高到61.5%、0.59 g/l·h和28.4 g/l，变异系数高达2.3%。
