Microbial communities, processes and functions in acid mine drainage ecosystems

Microbial Diversity and Community Assembly across Environmental Gradients in Acid Mine Drainage

“…also thrive in AMD environments and influence the oxidation of pyrite, greatly increasing the diversity of microbial communities [34,42]. To date, the dominant lineages detected in AMD environments are Proteobacteria, Nitrospira, Actinobacteria, Firmicutes, Acidobacteria, Aquificae in bacteria and Euryarchaeota, Crenarchaeota in archaea, as summarized by Chen et al [22]. More than 100 known genera have been detected in extreme AMD-generating conditions in South China, revealing a considerable microbial diversity in these environments (Figure 1).…”

Evaluating the microbial community and gene regulation involved in crystallization kinetics of ZnS formation in reduced environments

“…It is therefore beneficial for geochemists to expand their techniques into the "omics toolbox" to investigate these interactions and improve and develop reliable treatment technologies. Such endeavours have recently been undertaken in AMD-affected landscapes (Bertin et al, 2011;Chen et al, 2016;Hua et al, 2014) yet seldom have they been applied to remediation technologies for 12 AMD, despite many reviews stating the potential of such research Fraser et al, 2015;Garris et al, 2016;Moran et al, 2009;. This is not surprising, as sequencing platforms, bioinformatics pipelines, and constructed libraries are only now being optimized for large microbial meta data sets.…”

A Review of Acid Mine Drainage in a Water-Scarce Country: Case of South Africa

“…Chemical and biological reactions lead to the production of sulphuric acid with metal ions being released (Diz, 1997;Bigham and Cravotta, 2016). There are also organisms that exist in AMDs which can survive extreme acidic conditions such as Thiobacillus ferrooxidans and can thrive in pH ranging from 1.5 to 3.5 (Mühling et al, 2016;Chen et al, 2016). When microorganisms are present in AMD, the production of sulphuric acid occurs at a much higher rate since certain microorganisms obtain crucial energy from the oxidation of ferrous iron (Mühling et al, 2016;Kuang et al, 2016;Chen et al, 2016).…”

It is therefore important to evaluate cost effective measures for the removal of pollutants from contaminated sites in order to have safe drinking and useful water resources for the communities in need (Diz, 1997).…”
