Fig. 8From: Genetic engineering of Escherichia coli to improve L-phenylalanine productionTime course of L-Phe production by strain Xllp01 (a) and Xllp21 (b) in a 5 L fermenter. Dots meant residual glucose concentration, blocks meant the OD600 and triangles meant the L-Phe concentration. The final L-Phe yield and titer was basically constant among the three replicates and one of the three times was given as an example to show the fermentation resultsBack to article page
