- •
As-resistant endophytic and rhizospheric bacteria were investigated.
- •
All bacteria were AsV reducers except one strong AsIII oxidizer.
- •
Pteris vittata (PV) sporophytes took up more AsV than AsIII.
- •
Bacteria significantly enhanced As uptake and plant growth of PV.
- •
Large amount of AsIII effluxed by PV roots in sterile-media with 37.5 mg kg−1 AsV.
