“…sugars, polysaccharides, amino acids, aromatic acids, aliphatic acids, fatty acids, sterols, phenolic compounds, enzymes, proteins, plant growth regulators and secondary metabolites) which attract soil microorganisms into the rhizosphere where they multiply by several orders of magnitude [28]. In turn, microorganisms strongly in uence plant development and health by mineralizing organic matter, degrading organic pollutants, including persistent ones such as PCBs, improving heavy metal bioavailability by varying the degree of reaction of the soil (pH), releasing chelating substances (organic acids, siderophores) and promoting oxidation/reduction reactions [8,20]. In line with the above, the DNA sequencing data showed higher percentages of bacteria genera (i.e.…”
