Methanogenic inhibition by arsenic compounds.

Reyes Sierra-Alvarez¹, Irail Cortinas, Umur Yenal, Jim A Field.

Abstract

The acute acetoclastic methanogenic inhibition of several inorganic and organic arsenicals was assayed. Trivalent species, i.e., methylarsonous acid and arsenite, were highly inhibitory, with 50% inhibitory concentrations of 9.1 and 15.0 microM, respectively, whereas pentavalent species were generally nontoxic. The nitrophenylarsonate derivate, roxarsone, displayed moderate toxicity.
