摘要： Microorganisms producing 5-aminolevulinic acid which show a 5-aminolevulinic acid synthetase activity of 2 to 7 (nmol/min/mg protein) under aerobic culture conditions with a dissolved oxygen concentration of 0.70 to 6.60 ppm; a process for producing 5-aminolcvulinic acid characterized by culturing one or more microorganisms and harvesting 5-aminolevulinic acid from the obtained culture; a process for producing 5-aminolevulinic acid characterized by culturing 5-aminolevulinic acid-producing microorganims in a medium containing 5 to 500 mu M of iron components; and a method for culturing 5-aminolevulinic acid-producing microorganisms.
