Phytoremediation uses:
Phytoremediation integrates botanical processes with rhizosphere microbial ecology for contaminant removal, transformation, containment or detoxification using living plants and their associated microbiome. Roots actively exude low-molecular-weight organic acids such as citrate, malate, oxalate, sugars like glucose, amino acids and flavonoids that function as chemoattractants recruiting plant-growth-promoting rhizobacteria including Rhizobium, Pseudomonas fluorescens, Burkholderia and mycorrhizal fungi like Glomus that colonize root surface and interior, forming beneficial biofilm carrying cat
