In the original version of this Article, the final concentration of riboflavin in the supplemented LB medium for recombinant LkcE expression was incorrectly stated as 1 g L−1 (this was the concentration of the stock solution) and should have read 10–50 mg L−1. This error has been corrected in both the PDF and HTML versions of the Article.
