Geobacter species specialize in making electrical contacts with extracellular electron
acceptors and other organisms. This permits Geobacter species to fill important niches in a …

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 …

Microbes are difficult to culture. Consequently, the primary source of information about a
fundamental evolutionary topic, life's diversity, is the environmental distribution of gene …

ABSTRACT Dissimilatory Fe (III) and Mn (IV) reduction has an important influence on the
geochemistry of modern environments, and Fe (III)-reducing microorganisms, most notably …

Hundreds of millions of litres of petroleum enter the environment from both natural and
anthropogenic sources every year. The input from natural marine oil seeps alone would be …

Microorganisms that can form direct electrical connections with insoluble minerals,
electrodes, or other microorganisms can play an important role in some traditional as well as …

Microbial fuel cells (MFCs) are devices that can use bacterial metabolism to produce an
