We published that bacterial heme was over-produced in a recombinant Corynebacterium glutamicum expressing 5-aminolevulinic acid synthase (hemA⁺) under control of a constitutive promoter (P₁₈₀) and the heme-producing C. glutamicum had commercial potentials; as an iron feed additive for swine and as a preservative for lactic acid bacteria. To enhance the heme production, the hemA⁺ gene was expressed under controls of various promoters in the recombinant C. glutamicum. The hemA⁺ expression by P_gapA (a constitutive glycolytic promoter of glyceraldehyde-3-phosphate dehydrogenase) led 75% increase of heme production while the expression by P_H36 (a constitutive, very strong synthetic promoter) resulted in 50% decrease compared with the control (hemA⁺ expression by P180 constitutive promoter). The hemA⁺ expression by a late log-phase activating P_sod (an oxidative-stress responding promoter of superoxide dismutase) led 50% greater heme production than the control. The hemA⁺ expression led by a heat-shock responding chaperone promoter (P_dnaK) resulted in 121% increase of heme production at the optimized heat-shock conditions. The promoter strength and induction phase are discussed based on the results for the heme production at an industrial scale.
