Abstract

Aqueous metals are pervasive contaminants associated with historical mining. We produced and examined 16 metagenomes from a contaminated creek to investigate how anthropogenic metal contamination shapes the functional profiles of microbial communities. We then incorporated the metagenomic profiles and concurrently collected geochemical context into a multivariate model to examine correlations between stream geochemistry and microbial functional potential. Integrating the metagenomes with full geochemical profiles emphasised that even low metalloid concentrations shaped microbial functionality, seasonal shifts in copper bioavailability and arsenic exposure correlated with genetic variation, and copper resistomes were spatiotemporally distinct. This study provides new insights into microbial metabolic potential and microbe-metal(loid) interactions.

水体铜地球化学形成了一条恢复溪流中的沉积微生物抗性组。

水生金属是与历史采矿有关的普遍污染物。我们从一条受污染的溪流中提取并检测了 16 个元基因组，以研究人为金属污染如何影响微生物群落的功能特征。然后，我们将元基因组图谱和同时收集到的地球化学背景纳入一个多变量模型，以研究溪流地球化学与微生物功能潜力之间的相关性。将元基因组与完整的地球化学剖面整合在一起，可以发现即使金属类物质浓度很低，也会影响微生物的功能；铜的生物利用率和砷暴露的季节性变化与遗传变异相关；铜抗性基因组在时空上是不同的。这项研究为了解微生物的代谢潜力以及微生物与金属（loid）之间的相互作用提供了新的视角。

期刊介绍： The journal is identical in scope to Environmental Microbiology, shares the same editorial team and submission site, and will apply the same high level acceptance criteria. The two journals will be mutually supportive and evolve side-by-side. Environmental Microbiology Reports provides a high profile vehicle for publication of the most innovative, original and rigorous research in the field. The scope of the Journal encompasses the diversity of current research on microbial processes in the environment, microbial communities, interactions and evolution and includes, but is not limited to, the following: the structure, activities and communal behaviour of microbial communities microbial community genetics and evolutionary processes microbial symbioses, microbial interactions and interactions with plants, animals and abiotic factors microbes in the tree of life, microbial diversification and evolution population biology and clonal structure microbial metabolic and structural diversity microbial physiology, growth and survival microbes and surfaces, adhesion and biofouling responses to environmental signals and stress factors modelling and theory development pollution microbiology extremophiles and life in extreme and unusual little-explored habitats element cycles and biogeochemical processes, primary and secondary production microbes in a changing world, microbially-influenced global changes evolution and diversity of archaeal and bacterial viruses new technological developments in microbial ecology and evolution, in particular for the study of activities of microbial communities, non-culturable microorganisms and emerging pathogens.
