Trichoderma reesei FS10-C enhances phytoremediation of Cd-contaminated soil by Sedum plumbizincicola and associated soil microbial activities.

ABSTRACT: This study aimed to explore the effects of Trichoderma reesei FS10-C on the phytoremediation of Cd-contaminated soil by the hyperaccumulator Sedum plumbizincicola and on soil fertility. The Cd tolerance of T. reesei FS10-C was characterized and then a pot experiment was conducted to investigate the growth and Cd uptake of S. plumbizincicola with the addition of inoculation agents in the presence and absence of T. reesei FS10-C. The results indicated that FS10-C possessed high Cd resistance (up to 300 mg L(-1)). All inoculation agents investigated enhanced plant shoot biomass by 6-53% of fresh weight and 16-61% of dry weight and Cd uptake by the shoots by 10-53% compared with the control. All inoculation agents also played critical roles in increasing soil microbial biomass and microbial ac
