An investigation was carried out on alkaline protease production using solid state fermentation from Penicillium godlewskii SBSS 25 isolated from soil samples collected from Southern Kerala, India and its application as a detergent additive. The maximum protease yield (235 U/gds) were achieved with optimized process parameters like pH (9.0), temperature (35°C), moisture content (60%), nitrogen source (0.5% NH4NO 3), carbon source (4% glucose) and incubation time (96 h). The enzyme showed stability with a wide range of commercial detergents. These properties make this protease an ideal choice for application in detergent formulations.
