The aim of this study was to convert the cellulose and hemicellulose, in reed sawdust from the pulp mills, into yeast protein and xylo-oligosaccharide, then functionalize xylo-oligosaccharide as yeast feed. Both synchronous saccharification and fermentation and separate hydrolysis and fermentation of cellulase and Candida utilis were investigated to produce protein feed. By optimizing the fermentation conditions, 6.1 g/L of protein with 76.1% (7.1 g/L) xylo-oligosaccharide as the sugar was obtained. The final glucan and xylan utilization efficiencies in reed sawdust were 85.45% and 91.03%, respectively. Xylo-oligosaccharide enriched yeast protein feed from reed sawdust was thus realized by pretreatment, enzymatic hydrolysis and synchronous saccharification and fermentation.

这项研究的目的是将纸浆厂的芦苇锯末中的纤维素和半纤维素转化为酵母蛋白和木糖寡糖，然后将木糖寡糖功能化为酵母饲料。研究了同步糖化和发酵以及纤维素酶和and假丝酵母分别水解和发酵以生产蛋白质饲料。通过优化发酵条件，获得了6.1 g / L的蛋白质，其中木寡糖为76.1％（7.1 g / L）。芦苇木屑的最终葡聚糖和木聚糖利用率分别为85.45％和91.03％。因此，通过预处理，酶水解，同步糖化和发酵实现了芦苇锯末中富含木糖低聚糖的酵母蛋白饲料。
