Résumé:
The aim of this work was to highlight the most important bacterial strains involved in the process of sheep wool biodegradation by isolating and identify keratinase-producing bacterial isolates from wool. Thus, two bacterial samples were isolated and (S1, S2) in microbiology laboratories of the University of Mostaganem .These Isolates having a high proteolytic activity. The identification of these two strains was based on the morphological (macroscopic and microscopic) and chemical characteristics on the various biochemical tests available in the laboratory. These tests allowed us to classify and identify the bacteria strains. The two isolates identified were: S1 (Bacillus subtilis), S2 (Bacillus lichenformis).
