Unfortunately, the original publication of the article  contained the below errors.
In Fig. 5, the part Fig. 5c was incorrect and found to be the duplication of Fig. 5e. The corrected Fig. 5 is given below.
In “Abstract” under the Results section, the IPTG concentration that reads as “concentration, 0.5 mM” should read as “concentration, 0.05 mM”.
In “Methods, under the sub heading “Optimization of the production of 5-HT from L-Trp using E.coli BL21 (DE3) △ tnaA/BH4/HaDDC-SmTPH whole cell factory”, the sentence that reads as “The investment was carried out at varying concentration trajectories of L-Trp (0.5, 1.0, 1.5, 2.0 g/L), IPTG (0.25, 0.5, 0.75, and 1 mM)……”, should read as “The investment was carried out at varying concentration trajectories of L-Trp (0.5, 1.0, 1.5, 2.0 g/L), IPTG (0.025, 0.05, 0.075, and 0.1 mM)…….”.
The authors apologize for the mistakes.
