Fig. 2From: Production of p-amino-l-phenylalanine (l-PAPA) from glycerol by metabolic grafting of Escherichia coliGrowth of E. coli LJ110 in minimal media with glycerol and different l-PAPA concentrations. The cells were cultivated at 37 °C in the absence of l-PAPA (circles), or in the presence of 4 mM (squares), 8 mM (triangles), or 33 mM of l-PAPA (diamonds), respectively. Cultivations were performed twice and the mean values are givenBack to article page
