抄録

n-Octyl β-D-xylotrioside and xylobioside, which are effective next generation surfactants, can be prepared by the one-step reaction of xylan and n-octanol using acetone powder (acetone-dried cells) of Aureobasidium pullulans KK415 (ATCC 201145) as the enzyme source of xylanase in supercritical carbon dioxide (scCO2). Yields of the octyl glycosides were significantly increased using scCO2. Furthermore, without scCO2, n-octyl xylotrioside was hardly produced.
