摘要:The present invention relates to a recombinant microorganism with improved production capability of heme, coproporphyrin â…¢, uroporphyrin â…¢, zinc-coproporphyrin â…¢ (Zn-coproporphyrin â…¢), zinc-uroporphyrin â…¢ (Zn-uroporphyrin â…¢), and biliverdin, a preparation method therefor, and a method for production of heme, coproporphyrin â…¢, uroporphyrin â…¢, zinc-coproporphyrin â…¢, zinc-uroporphyrin â…¢, and biliverdin by using same. In the present invention, a synergistic effect of the introduction of genes related to the C4 and C5 pathways for synthesis of 5-aminolevulinic acid (ALA), genes related to the coproporphyrin â…¢-dependent pathway, and transcriptional regulatory factors was first evidenced through the improved porphyrin productivity effect of the recombinant microorganism. In addition, in contrast to the conventional recombinant microorganisms which are induced for extracellular production by introducing an extracellular secretion protein thereinto, the present invention first identified that the extracellular secretion of heme can be remarkably increased through the strategy of modifying microorganism cell walls. The recombinant microorganism according to the present invention is provided with enhanced production capability of porphyrin-based materials through the aforementioned metabolism engineering strategy and exhibits high productivity therefor. Thus, heme, coproporphyrin â…¢, uroporphyrin â…¢, zinc-coproporphyrin â…¢, zinc-uroporphyrin â…¢, and biliverdin, which are all high value-added materials, can be economically and efficiently produced by using the recombinant microorganism of the present invention.

摘要:A genetically engineered bacterium that produces D-pantothenic acid and a construction method therefor, and the use of the engineered bacterium in the preparation of D-pantothenic acid by means of microbial fermentation. In the present invention, mainly by means of: (1) increasing the copy number of key genes in the pantoic acid synthesis pathway in Escherichia coli organisms to further make carbon flux flow to the synthesis of D-pantothenic acid, and (2) in order to keep enhancing the flow of carbon flux to the synthesis of D-pantothenic acid, negatively regulating a transcription factor by means of weakening the nitrogen limitation and activating glycolytic front-end genes to pull the carbon flow so as to save phosphoenolpyruvic acid and reduce the central carbon flow that enters TCA, an engineered strain for producing D-pantothenic acid with no plasmid or antibiotic addition is obtained. Finally, the titer of D-pantothenic acid in the shake flask is increased by 87.2% compared to that of the starting strain, and reaches 5.43 g/L. After fermentation in a 5-L fermentation tank for 84 hours, the yield of D-pantothenic acid can reach 94.2 g/L.
