Abstract: The present invention relates to a method for preparing a mutant strain having high producibility of phytoene and a mutant strain prepared thereby. More particularly, a Deinococcus radiodurans mutant strain, prepared by the method of the present invention, having high producibility of phytoene, does not retain an artificial antibiotic-resistant gene, although constructed by introducing a metabolism engineering method, and has high producibility of phytoene. Thus, the mutant strain prepared according to the method can find useful applications in the mass production of phytoene.
