“…The LEfSe analysis further showed significant differences in biomarkers at the phylum and genus levels among the three groups. The class Sordariomycetes of the phylum Ascomycota and the class Microbotryomycetes of the phylum Basidiomycota were significantly enriched in CK, constituting the backbone of the fungal network in the manganese slag, and within it, the genus Fusarium is a pathogenic fungus [76] that has been demonstrated to display strong resistance to HMs in multiple studies [77,78]. In M0, only the order Agaricales of the phylum Basidiomycota was significantly enriched, similarly observed by Chen et al [27] in their study of SMC, with the high abundance of lignin and cellulose in SMC significantly consolidating its ecological niche [79].…”

The addition of soil amendments and plants in heavy metal-contaminated soil can result in a significant impact on physicochemical properties, microbial communities and heavy metal distribution, but the specific mechanisms remain to be explored. In this study, Koelreuteria paniculata was used as a test plant, spent mushroom compost (SMC) and attapulgite (ATP) were used as amendments, and manganese slag was used as a substrate. CK (100% slag), M0 (90% slag + 5% SMC + 5% ATP) and M1 (90% slag + 5% SMC + 5% ATP, planting K. paniculata) groups were assessed in a pilot-scale experiment to explore their different impacts on phytoremediation. The results indicated that adding the amendments significantly improved the pH of the manganese slag, enhancing and maintaining its fertility and water retention. Adding the amendments and planting K. paniculata (M1) significantly reduced the bioavailability and migration of heavy metals (HMs). The loss of Mn, Pb and Zn via runoff decreased by 15.7%, 8.4% and 10.2%, respectively, compared to CK. K. paniculata recruited and enriched beneficial fungi, inhibited pathogenic fungi, and a more stable fungal community was built. This significantly improved the soil quality, promoted plant growth and mitigated heavy metal toxicity. In conclusion, this study demonstrated that the addition of SMC-ATP and planting K. paniculata showed a good phytostabilization effect in the manganese slag and further revealed the response process of the fungal community in phytoremediation.

The microbial effect of long-term heavy metal pollution on farmland remains unclear. Here, we investigated microbial (bacterial and fungal) communities in topsoil and rhizosphere samples with heavy metal (Cd, Cu, Pb, and Zn) pollution from four different types of tillage plots around an abandoned zinc smelter set up 85 years ago and analyzed the complex relationship between microorganisms, plants, and heavy metals (HMs) in soil to guide strategies for further soil remediation measures. The abundance and diversity index results showed that the bacterial and fungal diversities of the four plots were significantly different. Meanwhile, correlation analysis of the microbial communities and HMs showed that bacteria Pseudomonas and fungi Chaetothyriales and Fusarium had a good tolerance for HM pollution, but bacteria Vicinamibacteraceae, JG30_KF_CM45, RB41, Gaiella, MB-A2-108, 67-14, and Microvirga, and fungi Glomerellales, Hypocreales, Chaetomium, and Mortierella all showed indications of being sensitive to HM toxicity. Our structural equation model (SEM) attributed the inhibition of Zn and the promotion of Cd to bacterial diversity, attributed a weak inhibition of Cd to fungal diversity, and revealed the effects of the tillage type on these diversities.
