The mixing and heat transfer phenomena within rotating drum bioreactors (RDBs) used for solid-state fermentation processes are poorly studied. The potential for the establishment of axial temperature gradients within the substrate bed was explored using a heat transfer model. For growth of Aspergill

## Abstract A previously published twoβdimensional discrete particle simulation model for radial mixing behavior of various slowly rotating drums for solidβstate fermentation (SSF) has been extended to a threeβdimensional model that also predicts axial mixing. Radial and axial mixing characteristic
A two-dimensional heat transfer model was validated against two experimental studies from the literature which describe the growth of Aspergillus niger during solid-state fermentation in packed bed bioreactors. With the same set of model parameters, the twodimensional model was able to describe both
Membrane overcultures of Rhizopus oligosporus were shifted from 37 to 50Β°C for 10 h and then re- turned to 37Β°C, mimicking the temporal temperature profiles which typically occur in SSF due to heat transfer limitations. Analysis with a modified two-phase growth model suggests that the temperature up
