摘要

This study aimed to demonstrate the contributions of arbuscular mycorrhizal fungi (AMF) on tolerance, metal/metalloid accumulation, and phytoremediation potentials of Jatropha multifida L. AMF were used as bioaugmentation agents in combination with J. multifida to treat heavy metal/metalloid (Cr, Fe, Pb, As, Cu, Ni, Zn, and Mn) contaminated landfill soil. Inoculated AMF enhanced the growth of J. multifida. The shoot fresh weight, shoot dry weight, and shoot length of the treated J. multifida were 33.32 ± 10.83 g, 14.26 ± 6.40 g, and 110.67 ± 10.69, respectively. Enhanced tolerance and accumulation of metals/metalloids (shoots: Cr (320.77 ± 73.58 mg/kg), Fe (953.20 ± 163.18 mg/kg), Pb (320.10 ± 51.68 mg/kg), As (10.23 ± 3.07 mg/kg), Zn (462.81 ± 208.04 mg/kg), and Ni (53.78 ± 7.84 mg/kg); roots: Cr (124.61 ± 19.26 mg/kg), Fe (152.33 ± 14.90 mg/kg), and Pb (67.52 ± 15.18 mg/kg)) were also monitored in AMF-inoculated J. multifida as compared to the unamended one. Improved physiological activities through the synthesis of various metabolites and antioxidant enzymes were witnessed in AMF-supplemented J. multifida. It is surmised that AMF improved the general well-being of J. multifida in metal/metalloid-contaminated landfill soil. Therefore, combining these fungi with J. multifida can be an important clean-up strategy for heavy metals/metalloids in landfill-polluted soil.
