Performance equations for the fed‐batch digestion of insoluble solid‐state substrates were developed based on a verified interfacial kinetic model for microbial uptake of these substrates. Fed‐batch anaerobic digestions of a suspension of stearic acid with a mean particle size of 2 μm were conducted to verify the derived equations. Agreement between the experimental and calculated results indicated the validity of these equations. The performance equations should be useful for describing the time courses of cell growth, substrate consumption and product accumulation in a fed‐batch digestion system with insoluble solid‐state organics as substrate.
