Biotechnology Letters Aims and scope Submit manuscript

Summary

β-glucosidase production was studied in solid-state cultivation by Aspergillus phoenicis on sugar beet pulps. The experiments were carried out in column incubators aerated with humidified air, at 30 °C. Results of physiological studies showed that the production of β-glucosidase from beet pulps in the solid state fermentation required : 70% moisture content, initial pH of about 4, and 107 spores/g substrate. β-glucosidase produced under these conditions could be removed from the solid medium with water, or stored in the form of a dried fermented product, for a direct use in the saccharification reactions.
