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

Interactions between plants and their endophytes alter metabolic functions ability to cope with abiotic stresses. In this study, high-throughput sequencing was used analyze the species diversity of in Cyperus esculentus var. sativus (CES) tubers under different heavy metal stress conditions. The results indicated that number observed endophytic increased (p < 0.05), leading changes composition. response tuber concentrations varied, certain bacteria fungi, such as Pseudomonas, Novosphingobium, Fusarium, showing abundance becoming dominant tubers. Additionally, new genera, Actinophytocola Monosporascus, emerged at specific 0.05). Fatty acid salvage enriched CES, which may play an important role assisting CES responding multiple These findings showed undergo adaptive support stress.

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

AbstractCadmium (Cd) is a metal widely known to cause toxic effects on the environment and human health. Soil represents rich habitat for fungi, which have certain characteristics in their cell wall that made them powerful tool biosorption of metals. Therefore, it was sought identify potential filamentous fungi different methods remediation contaminated areas. The identification from agricultural cultivation areas can tolerate Cd help cadmium processes occurred through isolation culture several microorganisms submitted screening experiments tolerance evaluation. Four strains genera Fusarium sp., Penicillium Aspergillus sp. were isolated. Those showed abilities stress caused by Cd, presenting index (Ti) 13.79 − 107.30%. Analyses FTIR demonstrated existence functional groups be involved coordination Cd2+ ions, as C = O stretches carboxyl amide-I. Results uptake range 0.88 3.61 mg g−1 dry biomass. results indicated isolated sites are highly tolerant promising implementation processes.Keywords: Biosorptionfungi biomassfungustoxic metals AcknowledgmentsThe authors gratefully acknowledge Analytical Center Federal University Fronteira Sul, provided Financiadora de Estudos e Projetos (FINEP), ICPE IFTR analysis.Authors’ contributionsAll contributed study’s conception design.
