Title

INVESTIGATING THE L-ASPARAGINASE PRODUCTION IN THE YEAST YARROWIA ‎LIPOLYTICA

Pages

  73-79

Abstract

 Introduction: L-Asparaginase catalyzes the hydrolysis of L-asparagine to L-aspartic acid and ammonia. This enzyme is used for the treatment of patients with acute lymphoblastic leukemia, melanosarcoma and lymphosarcoma. It is also used in the PRODUCTION of acrylamide-free foods. Considering the important applications of this enzyme, the aim of this study was to introduce a new microbial source for the PRODUCTION of eukaryotic L-asparaginase. Materials and Methods: The quality and quantity PRODUCTION of L-asparaginase was investigated in four strains of yeast YARROWIA LIPOLYTICA. The quality assessment of L-asparaginase PRODUCTION was done on asparagine minimal agar. Quantitative assay of the enzyme was done in Czapex Dox’s medium by spectrophotometric method using Nessler’s reagent. Results: All of four strains show that they are able to produce ASPARAGINASE making a purple halo around the colony. Y. lipolyticaDSM3286, DSM70562, DSM3218 and CBS6303 were produced 17.14, 11, 6.98 and 5.61 U/mL of ASPARAGINASE in Czapex Dox’s medium after 24 h, respectively. Discussion and Conclusion: Y. lipolytica DSM3286 was selected as the best ASPARAGINASE producer strain with the largest halo and the highest ASPARAGINASE PRODUCTION. The Y. lipolytica could be used as a potential source of L-asparaginase PRODUCTION.
