“…Other abundant phyla were Bacteroidetes, Actinobacteria, and Gemmatimonadetes (all ranging from 2.49 to 10.02%). The results obtained from the long-term heavy metal/metalloid-polluted sites are consistent with results obtained in independent studies in similar smelter areas ( Li et al, 2017 , 2020b ; Schneider et al, 2017 ; Bai et al, 2020 ). According to reports, the phylum Proteobacteria contain most of the heavy metal-resistant genes, followed by Actinobacteria and Bacteroidetes, as revealed by metagenome sequencing ( Yan et al, 2020 ).…”

“…The nutrients in the soil are closely involved in the biogeochemical cycling of elements mediated by soil microorganisms ( Bai et al, 2020 ). A recent study demonstrated through statistical analysis that A-N was positively correlated with the abundance and diversity of bacterial communities in Cd-contaminated soils ( Liu et al, 2020 ).…”

“…According to previous reports, heavy metal stress can affect a variety of functional genes and change the soil ecological functions that are catalyzed by functional groups ( Yin et al, 2015 ; Liu et al, 2018 ). Moreover, it has been reported that 30 functional groups in heavy metal-contaminated soil at a smelter site were affected by heavy metals/metalloids ( Bai et al, 2020 ). Similarly, our results indicated that there were eight functional groups that were significantly correlated with different heavy metals/metalloids, and the two main functional groups (chemoheterotrophy and aerobic chemoheterotrophy) exhibited remarkable negative correlation with heavy metals/metalloids except A-Pb ( Supplementary Table 7 ).…”

“…Spearman’s correlation analysis shows that heavy metals/metalloids and the physicochemical properties of the soils had a remarkable effect on multiple biogeochemical cycling, especially on the inhibition of chemoheterotrophy and airborne chemoheterotrophy ( Supplementary Table 7 ). However, a recent study at a smelter site showed that multiple functional groups related to various biogeochemical processes were selectively affected by different heavy metals/metalloids and the physicochemical properties of the soils, while most of the main functional groups associated with chemoheterotrophy and aerobic chemoheterotrophy were not significantly affected ( Bai et al, 2020 ). The conflicting results can be attributed to the changes in the environmental parameters for the different study areas.…”

“…It is known that toxic stress induced by heavy metals/metalloids can seriously affect the abundance and structure of the soil microbial communities and diversity ( Zhao et al, 2019 ) and change ecosystem functions ( Bai et al, 2020 ). For example, heavy metal/metalloid contaminants have affected a variety of functional genes and have altered the ecological functions of soils that were catalyzed by functional groups ( Yin et al, 2015 ; Liu et al, 2018 ), resulting in a reduction in the microbial diversity and further changing the structure of the soil microbial communities ( Liu et al, 2020 ).…”

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.

Soil Microbial Community Composition and Tolerance to Contaminants in an Urban Brownfield Site

et al. 2022

View full text Add to dashboard Cite

Brownfields are unused sites that contain hazardous substances due to previous commercial or industrial use. The sites are inhospitable for many organisms, but some fungi and microbes can tolerate and thrive in the nutrient-depleted and contaminated soils. However, few studies have characterized the impacts of long-term contamination on soil microbiome composition and diversity at brownfields. This study focuses on an urban brownfield—a former rail yard in Los Angeles that is contaminated with heavy metals, volatile organic compounds, and petroleum-derived pollutants. We anticipate that heavy metals and organic pollutants will shape soil microbiome diversity and that several candidate fungi and bacteria will be tolerant to the contaminants. We sequence three gene markers (16S ribosomal RNA, 18S ribosomal RNA, and the fungal internal transcribed spacer (FITS)) in 55 soil samples collected at five depths to (1) profile the composition of the soil microbiome across depths; (2) determine the extent to which hazardous chemicals predict microbiome variation; and (3) identify microbial taxonomic groups that may metabolize these contaminants. Detected contaminants in the samples included heavy metals, petroleum hydrocarbons, polycyclic aromatic hydrocarbons, and volatile organic compounds. Bacterial, eukaryotic, and fungal communities all varied with depth and with concentrations of arsenic, chromium, cobalt, and lead. 18S rRNA microbiome richness and fungal richness were positively correlated with lead and cobalt levels, respectively. Furthermore, bacterial Paenibacillus and Iamia, eukaryotic Actinochloris, and fungal Alternaria were enriched in contaminated soils compared to uncontaminated soils and represent taxa of interest for future bioremediation research. Based on our results, we recommend incorporating DNA-based multi-marker microbial community profiling at multiple sites and depths in brownfield site assessment standard methods and restoration.
