| Research Abstract |
In this study, it was uncovered the following things. i) The key enzymes which detoxicate phenolic endocrine-disrupting chemicals in Portulaca oleracea, that is a promising plant in phytoremediation, are 'polyphenol oxidase' and 'peroxidase'. ii) DNA sequences of these enzymes were decided. iii) These enzymes immobilized onto alginate and glass beads can detoxicate phenolic endocrine-disrupting chemicals under the conditions in which any plant was not able to grow. iv) Salvia cultivars showed a high BPA-eliminating ability under low temperature.
