A novel design of a large scale solid state fermenter, designated as PPSSF--Periodic Pressure Solid State Fermenter-- was constructed. Due to the respiration created by periodical variations of air pressure, air was uptaken / expelled from the fermenting mass and heat moved from the fermenter easily. It is possible to operate the unit at different capacities simply by adding or removing the bins. The results of its evaluation for enzyme formation by Trichoderma viride SL-1 indicated that a 2-3 fold increased cellulase production can be obtained in this system.
