The bioremediation of heavy metals contaminated soils with macrofungi is a new and promising approach; hence Agaricus bisporus (Large) sing has potentially shown accumulating ability to Cd contamination. This study focused on the tolerance response by A. bisporus to different contents of Cd in the closed cup and the flat stage of fruiting body development. The contents of Cd, soluble protein, sugar, low molecular weight organic acids (LMWOAs), and antioxidant activity were investigated. The bioaccumulation factor and transfer factor results revealed that Cd accumulated in the cap of A. bisporus more than that in the stipe with the highest content being 18.38 mg kg−1 dry weight at the closed cup stage under 414.28 mg kg−1 Cd stress. High Cd content stress increased soluble protein, proline, and malonaldehyde contents at both stages; while higher peroxidase, catalase, ascorbic acid peroxidase activities, and LMWOAs contents were only recorded at the closed cup stage. On the other hand, Superoxide dismutase activities and soluble sugar content showed a complex trend. Overall, these results have successfully established that A. bisporus could resort to modulating its metabolism to avoid the destructive effects of Cd stress and could successfully accumulate Cd in the soil, which is a promising prospect for the remediation of Cd-contaminated soils.

Many researchers have paid attention to solving the problem of multiple heavy metals pollution in the tailings area. However, the studies only stay at the laboratory level, which cannot completely demonstrate an efficient approach to remediate polluted environment due to tailings. This study aimed at investigating the effects of compound bacterial flora we constructed to remediate the tailings area of Linze County, Zhangye City, Gansu Province due to the accumulation of numerous heavy metals such as Pb, Cd and Mn. The remediation effects of different treatment groups were evaluated by monitoring the physical and chemical properties of soil and studying the bacterial community structure during the remediation process. Compared with the control (TCK), after 84 days of restoration, parameters of the tailings soil inoculated with the compound bacterial flora were improved, pH was decreased from 7.74 to 7.02, EC (electrical conductivity) was decreased by 21.15% ~70.49%, and activities of alkaline phosphatase, sucrase and urease were increased by 95.94%~99.64%、88.42%~98.43%、83.28%~86.95% respectively. Among the 43 identified core optional taxonomic units (OTUs), Proteobacteria (44.9%), Actinobacteriota (21.7%), Bacteroidota (17.9%) were the dominant bacterial phyla, and Sphingobacterium (20.2%), Arthrobacter (8.5%), Sphingomonas (6.1%) were the dominant bacterial genus. The results of alpha diversity showed that the bacterial diversity and richness of the treatment groups inoculated with compound bacterial flora were significantly higher than controls (TCK and HCK). The correlation analysis of RDA, VPA and Spearman showed that soil pH, WHC, EC, POR, TEMP and heavy metals had significant effects on the composition and distribution of bacterial communities. Our study monitored the changes of soil physical and chemical properties and bacterial community structure during the whole remediation process, which will provide a reference basis for the remediation approach to the soil polluted by multiple heavy metals.

The potential of Stropharia rugosoannulata as a microbial remediation material for cadmium (Cd)-contaminated soil lies in its capacity to absorb and accumulate Cd in its mycelia. This study utilized the TMT and LC−MS techniques to conduct integrated proteomic and metabolomic analyses with the aim of investigating the mycelial response mechanisms of S. rugosoannulata under low- and high-Cd stresses. The results revealed that mycelia employed a proactive defense mechanism to maintain their physiological functions, leading to reduced sensitivity to low-Cd stress. The ability of mycelia to withstand high levels of Cd stress was influenced primarily by the comprehensive regulation of six metabolic pathways, which led to a harmonious balance between nitrogen and carbohydrate metabolism and to reductions in oxidative stress and growth inhibition caused by Cd. The results provide valuable insights into the molecular mechanisms involved in the response of S. rugosoannulata mycelia to Cd stress.
