Summary

Optimal culture medium for production ofN-acetylneuraminate lyase (NANA lyase) by the gene-cloned strain ofEscherichia coli, E. coli(pNALl), was screened to develop the process for the industrial production of NANA lyase. Out of nutrients tested, corn steep liquor (CSL) and sugarcane molasses were superior nutrient sources for the enzyme production. Hyperproduction (6–8 units/ml-broth) was achieved on the medium consisted of CSL and molasses.
