Organic wastes, food wastes and trimming yard (FW and YT) were composted using selected fungal strains (Phanerochaete chrysosporium (PC), Lentinus tigrinus (LT), Aspergilus niger (ASP) and Penicillium Spp (PEN)) in a solid state bioconversion process. Results obtained at P ≤ 0.05 after ten harvests indicated the minimum value of germination index (GI) in the open system was 43 ± 105% while in the closed system it was 46 ± 132% respectively. The simplest zero and first order kinetic models described the microbial mineralization of carbon to nitrogen (C/N) relatively (R2 range of 0.87-0.99), but the second order model explained the observed kinetics of the solid state bioconversion (SSB) better with R2 range of 0.87–0.98 and a positive decay coefficient (k). The decay coefficient which indicates if all the components of the biomass decomposed at the same rate increases from -0.0584 to 2×10-4 for Phanerochaete chrysosporium stream & -0.0578 to 2×10-4 for Lentinus tigrinus stream in the open system across the zero, first and second order.
