Effective saccharification of kraft pulp by using a cellulase cocktail prepared from genetically engineered Aspergillus oryzae.

ABSTRACT

Kraft pulp is a promising feedstock for bioproduction. The efficiency of kraft pulp saccharification was improved by using a cellulase cocktail prepared from genetically engineered Aspergillus oryzae. Application of the cellulase cocktail was demonstrated by simultaneous saccharification and fermentation, using kraft pulp and non-cellulolytic yeast. Such application would make possible to do an efficient production of other chemicals from kraft pulp.
