Fig. 6From: Metabolic engineering of Escherichia coli BW25113 for the production of 5-Aminolevulinic Acid based on CRISPR/Cas9 mediated gene knockout and metabolic pathway modificationThe results of all mutant strains with respect to ALA production and growth rates. The ALA production and growth rates of the control D0 strain harboring pET28b-ALA-LAA are also indicated for comparisonBack to article page
