L-lactate producing part1

L-Lactic acid, one of the most important chiral molecules and organic acids, is produced via pyruvate from carbohydrates in diverse microorganisms catalyzed by an NAD+-dependent L-lactate dehydrogenase (ldhA).[1] Similar metabolic pathway has been found in a variety of organisms, to distinguish the differences, we renamed the heterogenous L-lactate dehydrogenase ldhE while homogenous one keeps original.

We choose a strong promoter+ strong RBS to construct L-Lactate part. The NAD+-dependent L-lactate dehydrogenase gene is from Lactobacillus casei.

But we found the yield was no different between BL21(blank) and BL21+ldhE(experientmental).
