摘要： The invention concerns isolated autotrophic aerobic bacteria capable of oxidising As(III) into As(V) using CO2 as only carbon source and As(III) as only energy source. The invention also concerns a use of said bacteria in treating media containing arsenic.

摘要： The invention relates to a method for biologically treating arsenic waste from the treatment of acid effluents. The present invention relates, in particular, to a method for treating acid effluents containing arsenic waste. In particular, a method for oxidising the arsenites contained in an acid effluent into arsenates, including: a step (i) consisting of adding a basic reagent to said effluent in order to change the pH thereof to a value greater than or equal to 2, and a step (ii) consisting of adding fermenting bacteria to the effluent resulting after step (i).
