THERMOSTABLE ALPHA-L-ARABINOFURANOSIDASE FROM AUREOBASIDIUM PULLULANS

摘要

A new alpha -L-arabinofuranosidase enzym 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 A. 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.
