They represent a major disposal and potentially severe pollution problem for the industry, also promising source of substances of high value. The aim of this study is the valorization of olive mill wastes (OMWW, olive cake, olive twigs and leaves) to produce enzymes with high industrial and biotechnological potential, by the solidstate fermentation technique (SSF), from isolated fungi present in olive mill wastewater and olive cake. A total of 47 strains were isolated and purified from these two residues. The metabolic potential of isolated strains was study by testing the hydrolytic enzymes activities of lipase, protease, amylase, cellulase, invertase, phytase and tannase on agar plate media containing different substrate. The monitoring of SSF has shown that the metabolic activity of these strains is extremely rapid using this technique. Our fungi collection contains a diversity of strains capable to producing a variety of enzymes of biotechnological interest. specialized biotechnological applications enzymes fungi olive oil wastes solid-state fermentation (SSF) valorization TUNISIE 084 49 1 12125 [18 p.] 2021 0255-965X https://www.documentation.ird.fr/hor/fdi:010081376 10.15835/nbha49112125 0255-965X [F B010081376] https://www.documentation.ird.fr/hor/fdi:010081376 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2021-06/010081376.pdf IRD - Base Horizon / Pleins textes 2021-06-15 2025-02-24 fdi:010081376 fre
