ABSTRACT: Groundwater with high arsenic (As) concentration constitutes a serious problem for crops, since rootscan accumulate the metalloid acting as the first stage of As distribution in the trophic chain. The aim of this research wasto elucidate the impact of a realistic As(V) dose in peanut and maize plants and to determine the contribution of plantgrowth promoting bacteria (PGPB) to metalloid translocation in both crops. The results obtained revealed thatrhizoinoculation of plants exposed to metalloid, contributed not only to improve growth but also to reduce As transport toshoots. Hence, inoculation of peanut and maize with the correct PGPB partner prevents metalloid translocation in plantsavoiding possible fruit contamination.
