Production of L-asparaginase by filamentous fungi
(2004-08) SARQUIS, Maria Inez de Moura; OLIVEIRA, Edna Maria Morais; SANTOS, Alberdan Silva; COSTA, Gisela Lara da
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.
