Title (EN) CONSORTIUM OF MICROORGANISMS AND METHOD FOR TREATING BODIES OF WATER CONTAMINATED WITH 1,2-DICHLOROETHANE
(FR) CONSORTIUM DE MICRO-ORGANISMES ET PROCÉDÉ DE TRAITEMENT DE MASSES D'EAU CONTAMINÉES PAR DU 1,2-DICHLOROÉTHANE
Abstract:
(EN) The present invention relates to a consortium of microorganisms useful for the bioremediation of bodies of water contaminated with 1,2-dichloroethane (1,2-DCA). In particular, the present invention relates to a consortium of microorganisms able to degrade 1,2-DCA to ethylene, substantially without producing toxic halogenated intermediates, said consortium, when present in an aqueous liquid, preferably under anaerobic conditions, being tolerant to a concentration of 1,2-DCA in solution in said aqueous liquid greater than or equal to 1000 mg/L, preferably comprised between 1000 mg/L and 4000 mg/L, and more preferably comprised between 2000 mg/L and 4000 mg/L. In a second aspect, the present invention relates to a method for the bioremediation of a body of water contaminated by 1,2-DCA, where in said body of water the concentration of 1,2-DCA may be greater than or equal to 1000 mg/L, preferably comprised between 1000 mg/L and 4000 mg/L and more preferably comprised between 2000 mg/L and 4000 mg/L, which comprises placing in contact with said body of water, preferably under anaerobic conditions, the aforementioned consortium of microorganisms able to degrade the 1,2- DCA.
(FR) La présente invention concerne un consortium de micro-organismes utiles pour la bioremédiation de masses d'eau contaminées par du 1,2-dichloroéthane (1,2-DCA). En particulier, la présente invention concerne un consortium de micro-organismes aptes à dégrader le 1,2-DCA en éthylène, sensiblement sans produire d'intermédiaires halogénés toxiques, ledit consortium, lorsqu'il est présent dans un liquide aqueux, de préférence dans des conditions anaérobies, étant tolérant à une concentration de 1,2-DCA en solution dans ledit liquide aqueux supérieure ou égale à 1 000 mg/l, de préférence comprise entre 1 000 mg/l et 4 000 mg/l, et plus préférentiellement comprise entre 2 000 mg/l et 4 000 mg/l. Selon un deuxième aspect, la présente invention concerne un procédé de bioremédiation d'une masse d'eau contaminée par du 1,2-DCA, où dans ladite masse d'eau, la concentration de 1,2-DCA peut être supérieure ou égale à 1 000 mg/l, de préférence comprise entre 1 000 mg/l et 4 000 mg/l et plus préférentiellement comprise entre 2 000 mg/l et 4 000 mg/l, qui comprend la mise en contact avec ladite masse d'eau, de préférence dans des conditions anaérobies, dudit consortium de micro-organismes aptes à dégrader le 1,2-DCA.
