Microorganisms are important drivers of material and energy circulation in freshwater ecosystems. Altered aquatic sedimentary environments disturbed by human activities affect microbial community composition. Concentrations of heavy metals, and sediment physicochemical properties, are described for 25 sediment samples collected from five habitat types (residential, duck farm, lotus pond, fish farm, and a reference reserve shallow freshwater lake site) around Baiyangdian Lake, China. Bacterial and fungal communities in sediments were determined using 16S rRNA and 18S rRNA high-throughput sequencing technology. Sediment physicochemical properties and heavy metal concentrations vary significantly among habitat types. Bacterial genera involved in S and N cycles are most abundant, followed by those that degrade organic pollutants, and are tolerant of heavy metals. Sediment bacterial Chao1 index is predominantly regulated by cobalt concentrations. The microbial communities within replicate samples within habitats are more similar to each other than they are between habitats. Redundancy analysis indicates Zn, pH, and TP are the main environment factors structuring bacterial communities, while fungal communities are most significantly influenced by Co and TP. The genus Cryptomonas is a food source for small zooplankton and fishes, and is mainly distributed in fish farm and lotus pond habitats. Species of Pseudallescheria that cause mycetoma, maduromycosis, and other infections in humans are highly abundant in duck farm and residential habitats. Species of Aleuria are saprobes; decompose organic matter, dead organisms, or biological excrement; and are highly accumulated in duck farm habitat.

“…Accordingly, the production of MeHg in paddy soils by anaerobic microorganisms has become a major public health issue (Meng et al., ). The microbial composition in soil is primarily determined by land‐use patterns (Wu et al., ), and the composition of microbial communities in soil may depend on the type of stress that is present (Tardy et al., ). In paddy soils surrounding mercury mining areas, mercury pollution (including total Hg and MeHg) significantly affects the bacterial community structure and the bacterial abundance is significantly correlated with the organic matter (OM) content (Liu, Wang, Zheng, Zhang, & He, ), although the presence of genes and mechanisms that are related to these conditions are still unknown.…”

Mercury can be a serious hazard to human health, especially in paddy soils surrounding mining areas. In this study, mercury (Hg)‐methylating microbes with the potential biomarker gene hgcA were obtained from 45 paddy soil samples in mercury mining areas in Fenghuang, Wanshan, and Xunyang. In different areas, the abundance of the hgcA gene was affected by different environmental factors, including organic matter, pH, total carbon content, total nitrogen content, and total mercury content. Phylogenetic analysis showed that hgcA microbes in paddy soils were potentially members of the phyla Proteobacteria, Euryarchaeota, Chloroflexi, and two unnamed groups. Canonical correspondence analysis showed that pH and organic matter impacted the hgcA gene diversity and the microbial community structures in paddy soils. The identification of Hg‐methylating microbes may be crucial for understanding mercury methylation/demethylation processes, which would be helpful in assessing the risk of methylmercury contamination in the food chain.

Prokaryotes play crucial roles in the rehabilitation process to restore the ecological integrity of disturbed areas. This work reports on the profiles of N-fixing microorganisms and Actinobacteria, from DGGE, the prokaryotic composition from nextgeneration sequencing (NGS) and physicochemical soil characteristics. We compared a deactivated mining site where mining ended about 10 years ago, when the revegetation process was begun (RV), and a reference site, with natural vegetation (NT), both located at Retiro das Almas Mine, in the Quadrilátero Ferrífero region, Minas Gerais, Brazil. In both sites, the most abundant archaeal and bacterial groups included Euryarchaeota, Thaumarchaeota, Proteobacteria, Actinobacteria, Acidobacteria, and Verrucomicrobia and revealed differences in their ecological metrics and distribution.Proteobacteria and Actinobacteria were most abundant in RV sites, while Acidobacteria and Verrucomicrobia were most abundant in NT sites. Less abundant phyla, such as Bathyarchaeota (Archaea) and GAL 15 (Bacteria) were found only in NT, while Gracilibacteria, Ignavibacteriae BJ-169, and BRC1 were only found in RV. The majority of identified bacterial genera were shared by RV and NT. Soil P, pH, and particle density were most significant (p < 0.05) in RV, while Fe, Ca, organic matter, potential acidity and dispersed clays, were most significant (p < 0.05) in NT, showing differences in soil characteristics, which led the prokaryotic composition in these sites. DGGE profiles of N-fixing microorganisms revealed N-fixing predominance in both sites, although after 10 years prokaryotes diversity increased in RV site. Our results revealed that prokaryotic structure and composition are indicative of RV soil resilience.
