Results showed that 11 out of the 51 strains tested can be used. They
belong to the species Aspergillus sp., Aspergillus niger, Penicillium
italicum. Penicillium sp. and Penicillium roquefortii. The mean protei
n enrichment yield is 20%. Nevertheless, the objective was not entirel
y achieved. Optimization of culture conditions, especially culture med
ia composition, is necessary to further increase these protein yields
to 50%.
