In the complex medium, it was found that adding alanine and aminoacetic acid could obviously improve the production of PNP ase and there was interaction between them. When the alanine concentration was in 80~140 mgL^(-1) and aminoacetic acid concentration was in 140~200 mgL^(-1), the high yield of fermentation could be ensured.
