PURPOSE:A blue-green algae is cultured in a medium containing iodide and/or iodate ions to produce a blue-green algae which is enriched in iodine nutrients which have actions to improve hypertension and accelerate growth and is suitable for use as a health food. CONSTITUTION:A culture medium containing inorganic nutrients such as sodium bicarbonate or sodium nitrate and, when needed, organic nutrients such as saccharides is combined with a water-soluble iodide such as sodium iodide or iodate such as calcium iodate to prepare a culture medium containing more than about 0.1 ppm, preferably 1-5,000 ppm of the ions. Then, a blue-green algae such as Spirulina platencis or Spirulina makishima is inoculated and cultured at 15-40 deg.C. Thus, the objective blue-green algae enriched in iodide nutrients is produced. |
