Metals, minerals and microbes: geomicrobiology and bioremediation
TL;DR: The ubiquity and importance of microbes in biosphere processes make geomicrobiology one of the most important concepts within microbiology, and one requiring an interdisciplinary approach to define environmental and applied significance and underpin exploitation in biotechnology.
Journal ArticleDOI
Global Water Pollution and Human Health
TL;DR: In this paper, the main groups of aquatic contaminants, their effects on human health, and approaches to mitigate pollution of freshwater resources are reviewed, particularly on inorganic and organic micropollutants including toxic metals and metalloids as well as a large variety of synthetic organic chemicals.
Journal ArticleDOI
Characterization and remediation of soils contaminated with uranium.
TL;DR: The objective of this paper is to develop a better understanding of the techniques for the remediation of soils polluted with radionuclides (uranium in particular), considering the chemical forms of uranium, including depleted uranium (DU) in soil and other environmental media, their characteristics and concentrations.
Journal ArticleDOI
Live wires: direct extracellular electron exchange for bioenergy and the bioremediation of energy-related contamination
TL;DR: The ability of Geobacter species to produce highly conductive electronic networks that function in water opens new possibilities in the emerging field of bioelectronics.
Journal ArticleDOI
Ecology and Biotechnology of Selenium-Respiring Bacteria
TL;DR: This review focuses on microorganisms that use selenate and selenite as terminal electron acceptors, in parallel to the well-studied sulfate-reducing bacteria, and overviews the significant advancements made in recent years on the role of SeRB in the biological selenium cycle.

TL;DR: The complete genome sequence of Geobacter sulfurreducens, a δ-proteobacterium, reveals unsuspected capabilities, including evidence of aerobic metabolism, one-carbon and complex carbon metabolism, motility, and chemotactic behavior, which suggest the organism has the potential for use in bioremediation of radioactive metals and in the generation of electricity.

TL;DR: Evidence from the quantitative PCR analysis corroborated information obtained from 16S rRNA gene clone libraries, indicating that members of the δ-Proteobacteria subdivision, including Anaeromyxobacter dehalogenans-related and Geobacter-related sequences, are important metal-reducing organisms in acidic subsurface sediments.
