Scientific Reports 8(1):2100(2018)

Researchers evaluated the potential applicability of plants with C3 and C4 carbon fixation pathways for the phytoremediation of soil affected by recalcitrant high-molecular-weight (HMW) PAHs. Results from a 60- and 120-d greenhouse study showed higher degradation of HMW PAHs in soil grown with C4 plants compared to C3 plants. No PAHs were detected in the maize cobs, sunflower, wallaby, and Sudan grass seeds at the end of the experiment. Study results revealed a substantial difference in the microbial populations between planted and unplanted soils, which in turn facilitated PAH degradation. https://www.nature.com/articles/s41598-018-20317-0
