The sentence in the original version of the paper: Although natural microbial producers of 5-ALA such as algae and photosynthetic bacteria have been discovered for decades [3, 4], they are not adopted in industrial 5-ALA production due to the relatively low titer, yield, and productivity. Has been corrected as follows: Although natural microbial producers of 5 ALA such as algae and photosynthetic bacteria have been discovered for decades [3, 4], the production levels are relatively low and the highest titer of 5-ALA is 3.6 g/L [5]. The authors also state that the correction does not affect the discussion or conclusions and that they sincerely apologize for the unintentional errors. The original article has been corrected.
