چکیده

L-asparaginase production was investigated in the filamentous fungi Aspergillus tamarii and Aspergillus terreus. The fungi were cultivated in medium containing different nitrogen sources. A. terreus showed the highest L-asparaginase (activity) production level (58 U/L) when cultivated in a 2% proline medium. Both fungi presented the lowest level of L-asparaginase production in the presence of glutamine and urea as nitrogen sources. These results suggest that L-asparaginase production by of filamentous fungi is under nitrogen regulation.

Introduction: L-asparaginase is an anti-neoblastic agent used in the chemotherapy of lymphoblastic leukemia. This enzyme is widely distributed among microorganisms, plants and animals, but microorganisms have proved to be a better alternative for L-asparaginase, thus facilitating its large-scale production. Actinomycetes are filamentous, Gram-positive bacteria widely distributed in the marine e...
