  • BIODEGRADATION OF ORGANIC POLLUTANTS BY A HALOPHILIC ARCHAEA
    Publication number: 20220298043
    Abstract: The present invention relates to a method for reducing the content of at least one pollutant selected from the group consisting of nitrobenzene, formate, phenol, 4,4?-Methylenedianilinc (MDA) and aniline of hypersaline wastewater, said method comprising the steps of (a) providing a composition A comprising hypersaline wastewater and said at least one pollutant, and (b) contacting composition A with Haloferax mediterranei cells, thereby generating a composition B comprising said composition A and cells of said at least one halophilic microbial strain. The present invention further concerns a method for the production of chlorine and sodium hydroxide. Further encompassed by the present invention is a composition comprising hypersaline wastewater, said at least one pollutant, and Haloferax mediterranei cells.
