Abstract
(EN) The present invention relates to the field of solution treatment using biological means, more particularly to the treatment of sulfate-containing solutions, specifically to a sulfate-reducing microbial consortium characterised in that it comprises a mixture of bacterial strains of Clostridium indolis, Clostridium sulfidigenes and Desulfovibrio sp. (RGM access code 2964). The invention also relates to a method for reducing sulfates in sulfate-containing solutions using the microbial consortium, which comprises the steps of: providing a mixture of bacterial strains of Clostridium indolis, Clostridium sulfidigenes and Desulfovibrio sp.; and contacting the acidic sulfate-containing solution with the mixture of bacterial strains and with an electron donor.
(ES) La presente invención se relaciona al campo de los tratamientos de soluciones por medios biológicos, más específicamente al tratamiento de soluciones que contienen sulfatos y en específico proporciona un consorcio microbiano reductor de sulfato que se caracteriza porque comprende una mezcla de cepas bacterianas de Clostridium indolis; Clostridium sulfidigenes; y Desulfovibrio sp (Código de Acceso RGM 2964). y un método para reducir sulfatos en soluciones que los contienen utilizando dicho consorcio microbiano que comprende los pasos de proporcionar una mezcla de cepas bacterianas de Clostridium indolis; Clostridium sulfidigenes; y Desulfovibrio sp y poner en contacto dicha solución ácida que contiene sulfatos con la mezcla de cepas bacterianas, y con un donador de electrones.
(FR) La présente invention se rapporte au domaine des traitements de solutions à l'aide de moyens biologiques, plus spécifiquement le traitement de solutions qui contiennent des sulfates et fournit spécifiquement un consortium microbien réducteur de sulfate qui est caractérisé en ce qu'il comprend un mélange de souches bactériennes de Clostridium indolis; Clostridium sulfidigenes; et Desulfovibrio sp (Code d'accès RGM 2964) et une méthode pour réduire les sulfates dans des solutions qui les contiennent au moyen dudit consortium microbien qui comprend les étapes consistant à fournir un mélange de souches bactériennes de Clostridium indolis; Clostridium sulfidigenes; y Desulfovibrio sp et à mettre en contact ladite solution acide qui contient des sulfates avec le mélange de souches bactériennes et avec un donneur d'électrons. .
