    Abstract
    Five hundred different cultures which belong to fifteen genera and forty-one species, isolated from cotton seeds and cotton seed products were studied for proteolytic, amylolytic and lipolytic activities. About 80% of the cultures tested proved to be protease-producers. High proportions of protease producing cultures were found in the genera Aspergillus (97.73%), Fusarium (95.83%) and Penicillium (46.34%). Most of the aspergilli which belong to the species A. flavus, A. fumigatus, A. sydowit and A. terreus displayed high proteolytic activities. About 88% of the cultures tested proved to be amylase-producers. High proportions of amylase producing cultures were found in the genera Drechslera (100%), Fusarium (95%), Penicillium (87%), Alternaria (81%) and Aspergillus (80%). About 88% of the cultures tested proved to be of lipolytic activity. High proportions of fipase producing cultures were found in the genera Fusarium (100%), Aspergillus (83.1%) and Penicillium (76.8%). Most of the lipase producers belonged to F. moniliforme (100%), F. oxysporum (98%), P. chrysogenum (95%), A. flavus (92%), A. fumigatus (91%), A. niger (85%) and P. notatum (81%).
