According to the theory of metabolic control fermentation, the dissertation focuses on fermentation condition and fermentation kinetics of L-tryptophan producing strain. The main research contents and results are as follows:
[1] The genetic markers of TQ2223,one L-Trp producing strain,were tested,and its production was also tested. Under the fermentation condition without being optimized, It could produe L-trptophan 6.86g/L.
[2]the batch fermentation condition of strain TQ2223 in shake f...
