WebThe lac operon is a delicate inducible gene expression element in bacteria. To efficiently induce gene expression, a sufficient dosage of an inducer, usually that of 500-1000 µM isopropyl β-D-1-thiogalactopyranoside (IPTG), is required to keep repressor LacI from its binding sites, which is a heavy cost burden in low-value-added products. toto st706 partsWeb15 Mar 2009 · Finding a lactose-fermenting (Lac +) mutant from an Escherichia coli Lac − strain allowed Monod to conclude that the ability of the Lac + mutant to utilize lactose was due to the formation of an adaptive enzyme, β-galactosidase (called lactase at that time).
