Title
(EN) METHOD OF DETOXIFYING ARSENIC
(FR) PROCEDE DE DESINTOXICATION D’ARSENIC
(JA) ヒ素の無害化方法
Abstract
(EN)
A method of detoxifying arsenic, capable of not only detoxifying an arsenic-containing treatment subject with the use of a microbe but also detoxifying the microbe per se. There is provided a method of detoxifying arsenic, comprising the steps of bringing a microbe having the activity of ingesting arsenic and synthesizing an organoarsenic compound into contact with an arsenic-containing treatment subject; retaining the mixture in an environment suitable for growth of the microbe; and causing the microbe to ingest the arsenic of the treatment subject and synthesize a harmless organoarsenic compound.
(FR)
Il est prévu un procédé de désintoxication d’arsenic, susceptible non seulement de désintoxiquer un sujet de traitement contenant de l'arsenic en utilisant un microbe, mais également de désintoxiquer le microbe proprement dit. Il est prévu un procédé de désintoxication d’arsenic, comprenant les phases de mise en contact d’un microbe ayant une fonction d’ingestion d’arsenic et de synthétisation d’un composé organoarsenic avec un sujet de traitement contenant de l'arsenic ; de rétention du mélange dans un environnement convenant à la croissance du microbe; et conduisant le microbe à ingérer l'arsenic du sujet de traitement et à synthétiser un composé organoarsenic inoffensif.
(JA)
 微生物によってヒ素を含む被処理物を無害化し、且つ、微生物自体も無害化するこ との可能なヒ素の無害化方法を提供する。  前記ヒ素の無害化方法は、ヒ素を含む被処理物に対して、ヒ素を取り込んで有機ヒ 素化合物を合成する活性のある微生物を接触させる工程と、前記微生物の育成環境下 に置く工程と、前記微生物に被処理物中のヒ素を取り込ませ、無害な有機ヒ素化合物 を合成させる工程とを有する。
