Abstract
An .alpha.-L-arabinofuranosidase enzyme which is highly thermostable, and is effective for the hydrolysis of arabinofuranosyl residues from L-arabinose containing polysaccharides and hemicelluloses is disclosed. The enzyme is produced by color variant Aureobasidium pullulans strain NRRL Y-21792. This .alpha.-L-arabinofuranosidase may be used in conjunction with xylanolytic enzymes for the treatment of hemicellulosic materials to produce fermentable sugars, particularly xylose and L-arabinose.
