Abstract

The aim of this study was to show the different protocols for the isolation, evaluation of the resistance capacity and identification of endophytic bacteria associated with different plant tissues adapted to environments contaminated with heavy metals. The protocols used have allowed the isolation and evaluation of a diversity of endophytic bacteria able to tolerate high concentrations of mercury and nickel.
