Arsenic-resistant bacteria solubilized arsenic in the growth media and increased growth of arsenic hyperaccumulator Pteris vittata L.

►Pteris vittata and arsenic-resistant bacteria effectively solubilized arsenic from FeAsO4 and AlAsO4 minerals. ► Fe was accumulated in the roots with arsenic, hindering their translocation in P. vittata. ► Arsenic-resistant bacteria increased plant biomass. ► As-induced P uptake was probably responsible for plant biomass increase.
