Abstract: The object of the invention is the plasmid pSheB, particularly a plasmid which may comprise a fragment of pSheB including the arr module and functional derivatives thereof, and strains containing such a plasmid, preferably the Shewanella sp. strain, deposited as KKP 2045p, which are capable of removing arsenic by dissolution of minerals and reduction of arsenates to arsenites. The object of the invention is also the method and the use of such bacterial strains or compositions which may comprise them, for the selective removal of arsenic from mineral resources, raw materials industry waste or soil.

Abstract: The invention provides novel strains Agrobacterium tumefaciens KKP 2039p and Paracoccus alcaliphilus KKP 2040p, the plasmid pSinA and its functional derivative, method for producing bacterial strains capable of chemolithotrophic arsenite oxidation and novel bacterial strains produced by this method. The invention also relates to the composition, comprising the novel bacterial strain or the plasmid pSinA and the use of these novel strains, as well as the method of bioaugmentation of an arsenic contaminated environment, particularly the method for the removal of arsenic from waters.
