Heavy metal pollution is a severe concern worldwide, owing to its harmful effects on ecosystems. Phytoremediation has been applied to remove heavy metals from water, soils, and sediments by using plants and associated microorganisms to restore contaminated sites. TheTyphagenus is one of the most important genera used in phytoremediation strategies because of its rapid growth rate, high biomass production, and the accumulation of heavy metals in its roots. Plant growth-promoting rhizobacteria have attracted much attention because they exert biochemical activities that improve plant growth, tolerance, and the accumulation of heavy metals in plant tissues. Because of their beneficial effects on plants, some studies have identified bacterial communities associated with the roots ofTyphaspecies growing in the presence of heavy metals. This review describes in detail the phytoremediation process and highlights the application ofTyphaspecies. Then, it describes bacterial communities associated with roots ofTyphagrowing in natural ecosystems and wetlands contaminated with heavy metals. Data indicated that bacteria from the phylumProteobacteriaare the primary colonizers of the rhizosphere and root-endosphere ofTyphaspecies growing in contaminated and non-contaminated environments.Proteobacteriainclude bacteria that can grow in different environments due to their ability to use various carbon sources. Some bacterial species exert biochemical activities that contribute to plant growth and tolerance to heavy metals and enhance phytoremediation.
