| Outline of Final Research Achievements |
In hydroponic culture, the use of O3MB can induce precipitation of metal ions from the medium, such as iron (Fe) and manganese (Mn). The addition of a chelator resulted in a concentration-dependent reduction in precipitates and the maintenance of Fe and Mn concentrations in the medium. The addition of a chelator did not alter the sterilizing effects of O3MB. Lettuce was unaffected in growth in the dissolved ozone concentration that was obtained bactericidal effect. These results indicate that the addition of a chelator to an O3MB-sterilized culture medium enabled the retention of dissolved Fe and Mn without affecting plant growth. Sterilization using O3MB plus a chelator may therefore be employed as an effective method in hydroponic culture.
