Production of β-Xylosidase by Aspergillus niger FTCC 5003 Using Palm Kernel Cake in a Packed-Bed Bioreactor

摘要

Aspergillus niger FTCC 5003 was cultivated on palm kernel cake as a substrate to produce β-xylosidase in solid substrate fermentation. The concurrent effects of three independent variables, including incubation temperature, initial moisture content o
