Modeling of solid state fermenter (SSF) plays a vital role in understanding the bio process, design and development. Packed bed solid state fermenter (PBSSF) showed certain specified application over another types of SSF. Overall efficiency of this column majorly depends on the temperature gradients forms inside the column. Modeling is a good tool for the fermenter design. In this research work kinetic and lumped heat transport model were used for simulating the microbial growth in the PBSSF. In the present work, Aspergillus oryzae was grown on Jowar straw and then experimental findings were validated by checking satisfactory fit with the lumped model.
