Abstract
The present invention relates to a method for biologically producing heme-iron through microorganism cultivation, and to an iron supplementing composition containing the heme-iron produced by the same. The present invention provides a method for biologically producing heme-iron through microorganism cultivation, making it possible to economically produce heme-iron or heme-iron preparations which can be safely used as an iron supplement.
Claims16
A method for biologically producing heme-iron which is characterized by the procedure comprising the step of cultivating a microorganism producing heme-iron and the step of recovering heme-iron from the culture solution and also characterized by the microorganism in which the activity of the enzymes involved in 5-aminolevulinic acid (5-ALA) synthesis is increased or the expression of the said enzymes is up-regulated.
A heme-iron preparation prepared from the culture solution of the heme-iron producing microorganism transformed with a recombinant plasmid containing at least one of the genes encoding HemA, MaeB, and DctA.
A heme-iron producing microorganism which is transformed by the recombinant plasmid containing at least one of the genes encoding HemA, MaeB, and DctA.
