Humic substances as electron acceptors for microbial respiration
HUMIC substances are heterogeneous high-molecular-weight organic materials which are ubiquitous in terrestrial and aquatic environments. They are resistant to microbial degradation1 and thus are notExpand

Microorganisms pumping iron: anaerobic microbial iron oxidation and reduction
Iron (Fe) has long been a recognized physiological requirement for life, yet for many microorganisms that persist in water, soils and sediments, its role extends well beyond that of a nutritionalExpand

Ubiquity and Diversity of Dissimilatory (Per)chlorate-Reducing Bacteria
ABSTRACT Environmental contamination with compounds containing oxyanions of chlorine, such as perchlorate or chlorate [(per)chlorate] or chlorine dioxide, has been a constantly growing problem overExpand

Microbial perchlorate reduction: rocket-fuelled metabolism
It is less than 7 years since perchlorate, a predominantly man-made toxic anion, was first identified as a significant water contaminant throughout the United States. Owing to its solubility andExpand

Anaerobic benzene oxidation coupled to nitrate reduction in pure culture by two strains of Dechloromonas
Benzene contamination is a significant problem. It is used in a wide range of manufacturing processes and is a primary component of petroleum-based fuels. Benzene is a hydrocarbon that is soluble,Expand

Mercury Methylation by Dissimilatory Iron-Reducing Bacteria
ABSTRACT The Hg-methylating ability of dissimilatory iron-reducing bacteria in the genera Geobacter, Desulfuromonas, and Shewanella was examined. All of the Geobacter and Desulfuromonas strainsExpand

Geothrix fermentans gen. nov., sp. nov., a novel Fe(III)-reducing bacterium from a hydrocarbon-contaminated aquifer.
In an attempt to understand better the micro-organisms involved in anaerobic degradation of aromatic hydrocarbons in the Fe(III)-reducing zone of petroleum-contaminated aquifers, Fe(III)-reducingExpand

Dissimilatory arsenate and sulfate reduction in Desulfotomaculum auripigmentum sp. nov.
Abstract A newly discovered arsenate-reducing bacterium, strain OREX-4, differed significantly from strains MIT-13 and SES-3, the previously described arsenate-reducing isolates, which grew onExpand
