| 英文摘要 | Considerable evidence exists that microorganisms play a significant role in the remediation of soil contaminated with heavy metals. Aspergillus aculeatus (A. aculeatus) isolated from Cd-polluted soil has been shown to increase the tolerance of turfgrasses to Cd stress. In this study, we assessed the tolerance, biosorption capacity for Cd and surface characteristics of this fungus and investigated the effect of plant inoculation with A. aculeatus on the lipid peroxidation, antioxidant activities and photosynthetic rates in rice cultivated in Cd-contaminated soil. The results indicated that the removal efficiency of A. aculeatus was 46.8% at a Cd concentration of 10 mg L-1. The A. aculeatus strains had the capacity to produce indole acetic acid, siderophore, and 1-aminocyclopropane-1-carboxylate deaminase and to solubilize phosphate. The O-2(-) accumulation and the amount of MDA in rice roots inoculated with A. aculeatus were significantly lower than those in uninoculated plants. Nevertheless, no decrease in leaf ROS accumulation and photosynthetic activity was observed between the inoculated and uninoculated plants. Inoculation with A. aculeatus contained more of the ROS-scavenging metabolite GSH, a higher GSH/GSSG ratio, and higher antioxidative enzyme (SOD, POD, and CAT) activities, possibly explaining the lower ROS concentrations observed in inoculated roots in the presence of Cd. These results suggest that application of A. aculeatus has the potential to protect crops against Cd stress. |
