摘要：
The fermentation of rice bran by Aspergillus niger to produce glucoamylase was carried out in a packed-bed bioreactor. The optimum packing density of medium was between 586 and 858 g/l. Also, thermal conductivity (K) was determined and an experimental correlation with packing density (PD) and moisture (M) was obtained as K = 47.5080 + 0.0115PD + 0.1295M - 6.0737ln(PD)- 5.5555ln(M).
