<I>n</I>-Octyl <I>β</I>-<FONT SIZE="-2">D</FONT>-xylotrioside and xylobioside, which are effective next generation surfactants, can be prepared by the one-step reaction of xylan and <I>n</I>-octanol using acetone powder (acetone-dried cells) of <I>Aureobasidium pullulans</I> KK415 (ATCC 201145) as the enzyme source of xylanase in supercritical carbon dioxide (scCO<SUB>2</SUB>). Yields of the octyl glycosides were significantly increased using scCO<SUB>2</SUB>. Furthermore, without scCO<SUB>2</SUB>, <I>n</I>-octyl xylotrioside was hardly produced.
