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 …

Anaerobic dissimilatory ferric iron-reducing and ferrous iron-oxidizing bacteria gain energy
through reduction or oxidation of iron minerals and presumably play an important role in …

Biohydrogen production (BHP) can be achieved by direct or indirect biophotolysis, photo-
fermentation and dark fermentation, whereof only the latter does not require the input of light …

With a rich variety of chemical energy sources and steep physical and chemical gradients,
hydrothermal vent systems offer a range of habitats to support microbial life. Cultivation …

There is an increased interest in using thermophilic bacteria for the production of bioethanol
from complex lignocellulosic biomass due to their higher operating temperatures and broad …

Hydrogen is considered as the fuel of the future by virtue of the fact that it is carbon-neutral
renewable energy source having the highest energy content per unit mass of any known …

Hydrogen is considered as a pollution-free fuel of the future because of several reasons: It
does not contain carbon, having maximum energy content per unit mass among all the …

Several thermophilic anaerobic bacteria with keratinolytic activity growing at temperatures
between 50° C and 90° C were isolated from samples collected on the island of São Miguel …

A new, extremely thermophilic bacterium, designated strain MB4T, was isolated from a
Chinese hot spring. The new isolate was an obligately anaerobic, rod-shaped, gram …
