The present work aimed to isolate lead- and cadmium-tolerant endophytic bacteria from the roots of <i>Typha latifolia</i> growing in a site contaminated with these heavy metals. Endophytic bacteria were characterized according to Pb and Cd tolerance, plant-growth-promoting rhizobacteria activities, and their effect on <i>T. latifolia</i> seedlings exposed and non-exposed to Pb and Cd. Pb-tolerant isolates were identified as <i>Pseudomonas azotoformans</i> JEP3, <i>P. fluorescens</i> JEP8, and <i>P. gessardii</i> JEP33, while Cd-tolerant bacteria were identified as <i>P. veronii</i> JEC8, JEC9, and JEC11.
