Abstract

L’invention se rapporte à une nouvelle souche de bactéries Stenotrophomonas, à savoir la souche Stenotrophomonas sp. Br8 déposée auprès de la Colección Española de Cultivos Tipo sous le numéro d’accession CECT 9810. Elle se rapporte également à un matériau comprenant des bactéries de cette souche immobilisées dans des matrices poreuses et à l’utilisation desdites bactéries ou dudit matériau pour décontaminer en uranium(VI) des eaux ou des effluents aqueux. Applications : bioremédiation d’eaux de cours d’eau, de plans d’eau, naturels ou artificiels, ou de nappes phréatiques ; décontamination d’effluents aqueux issus d’activités d’extraction et/ou de traitement de minerais uranifères ou de minerais de phosphates contenant de l’uranium.The invention relates to a new strain of Stenotrophomonas bacteria, namely the Stenotrophomonas sp. Br8 deposited with the Colección Española de Cultivos Tipo under accession number CECT 9810. It also relates to a material comprising bacteria of this strain immobilized in porous matrices and to the use of said bacteria or said material to decontaminate in uranium(VI) from water or aqueous effluents. Applications: bioremediation of water from streams, bodies of water, natural or artificial, or groundwater; decontamination of aqueous effluents from extraction and/or processing activities of uranium ores or phosphate ores containing uranium.
