A wide array of microorganisms, including many novel, phylogenetically deeply rooted taxa,
survive and thrive in extreme environments. These unique and reduced-complexity …

Microbial rhodopsins are diverse photoreceptive proteins containing a retinal chromophore
and are found in all domains of cellular life and are even encoded in genomes of viruses …

Charged and polar groups, through forming ion pairs, hydrogen bonds, and other less
specific electrostatic interactions, impart important properties to proteins. Modulation of the …

Hypersaline environments with salt concentrations up to NaCl saturation are inhabited by a
great diversity of microorganisms belonging to the three domains of life. They all must cope …

Organisms of all domains of life use photoreceptor proteins to sense and respond to light.
The light-sensitivity of photoreceptor proteins arises from bound chromophores such as …

Members of the diverse bacterial phylum Bacteroidetes have colonized virtually all types of
habitats on Earth. They are among the major members of the microbiota of animals …

Halophiles are found in all three domains of life. Within the Bacteria we know halophiles
within the phyla Cyanobacteria, Proteobacteria, Firmicutes, Actinobacteria, Spirochaetes …

Life at high salt concentrations is energetically expensive. The upper salt concentration limit
at which different dissimilatory processes occur in nature appears to be determined to a …

Genome sequencing projects are revealing new information about the distribution and
evolution of photosynthesis and phototrophy. Although coverage of the five phyla containing …

Bacterial Biogeochemistry, Third Edition focuses on bacterial metabolism and its relevance
to the environment, including the decomposition of soil, food chains, nitrogen fixation …
