“…While other predominant bacteria Sphingomonas and Gemmatimonas were moderately correlated with heavy metals/metalloids except A-Pb. Similar to this study, some researchers found that Sphingomonas was highly resistant to arsenic and antimony (Li et al, 2021b), and another study proved that Gemmatimonas was more abundant in heavily polluted areas (Guo et al, 2017).…”

Microorganisms play a fundamental role in biogeochemical cycling and are highly sensitive to environmental factors, including the physiochemical properties of the soils and the concentrations of heavy metals/metalloids. In this study, high-throughput sequencing of the 16S rRNA gene was used to study the microbial communities of farmland soils in farmland in the vicinity of a lead–zinc smelter. Proteobacteria, Acidobacteria, Actinobacteria, Bacteroidetes, and Gemmatimonadetes were the predominant phyla in the sites of interest. Sphingomonas, Gemmatimonas, Lysobacter, Flavisolibacter, and Chitinophaga were heavy metal-/metalloid-tolerant microbial groups with potential for bioremediation of the heavy metal/metalloid contaminated soils. However, the bacterial diversity was different for the different sites. The contents of heavy metal/metalloid species and the soil properties were studied to evaluate the effect on the soil bacterial communities. The Mantel test revealed that soil pH, total cadmium (T-Cd), and available arsenic played a vital role in determining the structure of the microbial communities. Further, we analyzed statistically the heavy metals/metalloids and the soil properties, and the results revealed that the microbial richness and diversity were regulated mainly by the soil properties, which correlated positively with organic matter and available nitrogen, while available phosphorus and available potassium were negatively correlated. The functional annotation of the prokaryotic taxa (FAPROTAX) method was used to predict the function of the microbial communities. Chemoheterotrophy and airborne chemoheterotrophy of the main microbial community functions were inhibited by soil pH and the heavy metals/metalloids, except in the case of available lead. Mantel tests revealed that T-Cd and available zinc were the dominant factors affecting the functions of the microbial communities. Overall, the research indicated that in contaminated soils, the presence of multiple heavy metals/metalloids, and the soil properties synergistically shaped the structure and function of the microbial communities.

“…As an important component of the ecosystem, soil organisms affect terrestrial ecosystem functions by regulating soil acidity, mediating soil carbon dynamic, stabilizing toxic pollutants, and promoting element cycling ( Chen et al, 2016 ; Fierer, 2017 ; Sun et al, 2017 , 2018b ). In a mine land co-contaminated with arsenic (As) and antimony (Sb), the potential tolerant bacteria Bradyrhizobium , Sphingomonas , Nocardioides , Burkholderia , and Streptomyces induced As and Sb biogeochemical cycling, as well as contributed to the cycling of C (C fixation), N (nitrate/nitrite, N fixation), and S (sulfate reduction) ( Li et al, 2021 ). The rhizospheric microbes serve as an important assistor for plants to survive in harsh environments ( Grandlic et al, 2009 ; Mishra et al, 2017 ; Sun et al, 2018b ).…”

Plant-Soil Feedbacks for the Restoration of Degraded Mine Lands: A Review

Much effort has been made to remediate the degraded mine lands that bring severe impacts to the natural environments. However, it remains unclear what drives the recovery of biodiversity and ecosystem functions, making the restoration of these fragile ecosystems a big challenge. The interactions among plant species, soil communities, and abiotic conditions, i.e., plant-soil feedbacks (PSFs), significantly influence vegetation development, plant community structure, and ultimately regulate the recovery of ecosystem multi-functionality. Here, we present a conceptual framework concerning PSFs patterns and potential mechanisms in degraded mine lands. Different from healthy ecosystems, mine lands are generally featured with harsh physical and chemical properties, which may have different PSFs and should be considered during the restoration. Usually, pioneer plants colonized in the mine lands can adapt to the stressful environment by forming tolerant functional traits and gathering specific soil microbial communities. Understanding the mechanisms of PSFs would enhance our ability to predict and alter both the composition of above- and below-ground communities, and improve the recovery of ecosystem functions in degraded mine lands. Finally, we put forward some challenges of the current PSFs study and discuss avenues for further research in the ecological restoration of degraded mine lands.

“…Other studies have determined that the presence of metal(oids) can influence biogeochemical cycles, namely, those of C, N, and S, by promoting specific chemical reactions and the enrichment of chemoautotrophs. For example, As(III)-oxidizing bacteria can couple this process with nitrate reduction ( 20 – 22 ), hence highlighting the importance of assessing the metabolic potential of indigenous microbes and communities.…”
