ABSTRACT:
The invention relates to isolation of an Aspergillus gene encoding rhamnogalacturonase (RG-ase) and the construction of recombinant Aspergillus strains with overexpression of RG-ase. These strains can be used for the commercial production of RG-ase. RG-ase is an important enzyme in processes requiring the degradation and/or modification of pectin or modification of pectin-containing vegetable or plant cell wall material. RG-ase may be used in various applications, including the processing of fruits and vegetables, in the extraction of components from vegetable material or for improving the functionality of pectin or pectin-containing vegetable material, food material or plant cell wall material.
