“…For this reason, there is a growing interest in the use of bioremediation, either through the use of plants, microorganisms or both (phytorhizoremediation) for the recovery of these environments [ 5 , 6 , 48 , 49 , 50 ]. There are multiple studies on the use of microorganisms for the recovery of heavy-metal-contaminated areas [ 5 , 8 , 48 , 51 , 52 , 53 , 54 ] and the benefits of adding PGPB that favor the process. Likewise, it is important to know the impact that their addition generates in the composition and biological diversity of the communities that host them, as well as the impact that the addition of microorganisms can exert on the expression of AR mechanisms of microbial communities.…”
