Abstract
Cello-oligosaccharide has drawn an increasing attention as the nutritional ingredients of dietary supplements, whose quality is affected by the concentration of monosaccharide. In the present study, an effective process was developed for the simultaneous production of cello-oligosaccharide and glucose mono-decanoate from lignocellulose by enzymatic esterification. During the process, the excessive glucose in cello-oligosaccharide was converted into glucose mono-decanoate, which is a well-known biodegradable nonionic surfactant. The filter paper was initially used as the model to investigate the feasibility of the process, in which the purity of resultant cello-oligosaccharide was increased from 33.3% to 74.3%, simultaneously producing glucose mono-decanoate with a purity of 92.3%. Further verification of 3 kinds of lignocelluloses (switchgrass, cornstalk, and reed) also indicated a good performance of the process. The present process provided an effective strategy to increase the purity of resultant cello-oligosaccharide with the simultaneous production of high value–added products of sugar monoester.

Applied Biochemistry and Biotechnology
Introduction The cello-oligosaccharide has been becoming an important prebiotics, which could facilitate calcium metabolism, improve bone health, and regulate inflammatory [1]. In addition, cellooligosaccharide is also well-known as the surfactant, thickening agents, and glues [2]. Thus, it has been widely applied in food processing, dietary supplements, and feed industry [3, 4]. At present, the production of cello-oligosaccharide from celluloses included the chemical hydrolysis, physical hydrolysis, and enzymatic hydrolysis. Pang et al. produced cellooligosaccharide by chemical hydrolysis of cellulose with formic/hydrochloric acid. The products consist of cellobiose, cellotriose, cellotetraose, and cellopentaose [5]. Another production of cello-oligosaccharide via physical hydrolysis by supercritical
