Xylobiose (X2) is recognized to possess great prebiotic function and to be highly favorable for applicationin food and prebiotic industries. In this study, we demonstrated that the cloned b-xylosidase of Bacilluspumilus IPO could be utilized to produce X2 via the reaction of xylose(X1)!xylobiose(X2). The use ofsuch enzyme in the X1!X2 reaction was found to give much higher X2 reaction yield and reactionefficiency, compared to those reported in the literature. Furthermore, we developed an efficientsimulated moving bed (SMB) chromatographic process that could recover X2 from the reaction outputwith nearly 100% purity and 92% recovery on a continuous-separation mode. The developed SMB processcould also recover the unreacted X1 almost completely, which leaves room for a further increase in theoverall X2 reaction yield by reusing the recovered X1 from the SMB as the reactant of the upstreamprocessing (i.e., B. pumilus IPO b-xylosidase X1!X2 reaction). The results of this study will enable ahighly economical and environmentally-friendly production of high-purity X2 from X1.

From the processing method, which used to be hand-crafted, various devices have been developed and developed into a processing method that combines design and advanced equipment. Among the many processing equipment that is widely used in the manufacturing industry, CNC Machine are becoming more common than in the past, and the supply of CNC Machine is rapidly underway in Korea in line with the increasing trend of woodworking rooms. However, in the field of furniture design, CNC Machine are only used as mechanical means to compensate for the shortcomings of manual work. In this study, patterns and forms were used in the subject of tradition to emphasize craft sensibility through CNC processing. Traditional patterns are shaped like shapes and dots, which contain the lives and cultures of the people of that time. This paper aims to describe the definition and characteristics of traditional patterns and CNC processing, present the design of furniture using traditional patterns and CNC’s air methods, and contribute to the popularization of households using various traditional patterns.
