| Abstract: | Background Arsenic is known as a toxic metalloid, which primarily exists in inorganic form As(III) and As(V)] and can be transformed
by microbial redox processes in the natural environment. As(III) is much more toxic and mobile than As(V), hence microbial
arsenic redox transformation has a major impact on arsenic toxiCity and mobility which can greatly influence the human health.
Our main purpose was to investigate the distribution and diversity of microbial arsenite-resistant species in three different
arsenic-contaminated soils, and further study the As(III) resistance levels and related functional genes of these species. |
