J Biosci Bioeng. 2012 Feb;113(2):239-41. doi: 10.1016/j.jbiosc.2011.10.008. Epub 2011 Nov 17.

Abstract

The immobilized endo- and exo-arabinanases from Caldicellulosiruptor saccharolyticus produced continuously an average of 16.5 gl(-1)l-arabinose from 20 gl(-1) sugar beet arabinan at pH 5.0 and 75°C for 216 h, with a productivity of 9.9 gl(-1)h(-1) and a conversion yield of 83%.
