Summary

Production of hemicellulolytic enzymes required in the hydrolysis of different xylans was investigated using strains of seven species of Aspergillus. Of the strains producing highest levels of xylanolytic activities, a. foetidus VTT-D-71002 was apparently non-cellulolytic and could therefore be a possible source of cellulase-free hemicellulase for applications in the pulping industry. The non-metabolizable synthetic xylobiose analogue β-methyl-D-xyloside was the best xylanase inducer of the materials tested. Batches of hemicellulase produced in laboratory scale fermentations on practical media were tested in the hydrolysis of both cellulosic and hemicellulosic substrates.
