Tannage Résumé : Solid-state fermentation (SSF) for the production of an alkaline protease was carried out using the microorganism Rhizopus oryzae. The enzyme is stable from pH 3-11 and at temperature up to 80°C. During optimization of the different environmental parameters for the unhairing of skins, 46% hydration, 83% humidity, pH 8.0 and incubation period of 2 hours were found to produce the best results. Then the physical properties of the skins unhaired by enzymatic treatment and the chemical treatment were compared, the former was found to give better quality leather.
