Biosynthesis of L-phenylalanine and trans-cinnamic acid by P. putida CM12-5 and P. putida CM12-5 (pPALN)

	[L-Phe] T 0 h (mg L−1)	[L-Phe] T 24 h (mg L−1)	[tCA] T 24 h (mg L−1)
CM12-5	0	217.2 ± 41.8	0
	173.2 ± 0.9	356.9 ± 5.5	0
CM12-5 (pPALN)	0	141.8 ± 33.8	91.0 ± 11.2
	173.6 ± 0.1	263.9 ± 41.0	119.7 ± 19.3

Assays were done in M9 minimal medium with glucose as the sole C-source with and without the addition of 1 mM L-Phe (173 ± 1 mg/L)

The concentrationof L-phenylalanine and trans-cinnamic acid was determined after 24 h’ cultivation

The data in the table are the average and standard deviation of three independent assays
