Liquefied wheat bran as carbon source and inducer in high-solids submerged cultivation of Aspergillus niger for xylanase production

This study revealed that xylanase production was favored by a substrate liquefied using the optimum pH (4.8) and temperature conditions (50 °C) of the commercial enzymatic preparation (2.8 FPU/g solids), while the liquefaction time was not significant above 6 h. The proposed strategy resulted in xylanase activity 5-fold higher than for a cultivation with non-liquefied substrate (control). These findings should contribute to the development of xylanase production processes using high solids loading submerged cultivation in conventional large-scale bioreactors.
