The Role of Microorganisms in Removal of Sulfates from Artistic Stonework
The presence of organic matter on artistic stonework can be credited to inadequate historical renovations, lysis of microbial cells, primary surface...

Evaluation of the roles of hydrophobic residues in the N-terminal region of archaeal trehalase in its folding
AbstractThermoplasma trehalase Tvn1315 is predicted to be composed of a β-sandwich domain (BD) and a catalytic domain (CD) based on the structure of...

Archaeal Cell Walls
The cell wall of archaea, as of any other prokaryote, is surrounding the cell outside the cytoplasmic membrane and is mediating the interaction with...

Formation of Fatty Acids
Fatty acids are the building blocks of diverse membrane lipids and therefore are essential for the viability of all cells, except the Archaea where...

Geobiological feedbacks and the evolution of thermoacidophiles
Oxygen-dependent microbial oxidation of sulfur compounds leads to the acidification of natural waters. How acidophiles and their acidic habitats...

Formation of Isoprenoids
Isoprenoids, also known as terpenoids, are a diverse group of metabolites produced in all free-living organisms. They play an indispensable role in a...

An overview of 25 years of research on Thermococcus kodakarensis, a genetically versatile model organism for archaeal research
Almost 25 years have passed since the discovery of a planktonic, heterotrophic, hyperthermophilic archaeon named Thermococcus kodakarensis KOD1,...

Biofilm Lifestyle of Thermophile and Acidophile Archaea
In this chapter we provide an overview of the biofilm lifestyle of (hyper) thermophilic and acidophilic archaea. In contrast to the bacterial domain,...

A review of the mechanisms of mineral-based metabolism in early Earth analog rock-hosted hydrothermal ecosystems
Prior to the advent of oxygenic photosynthesis ~ 2.8–3.2 Ga, life was dependent on chemical energy captured from oxidation–reduction reactions...

Thermoplasmatales and sulfur-oxidizing bacteria dominate the microbial community at the surface water of a CO2-rich hydrothermal spring located in Tenorio Volcano National Park, Costa Rica
Here we report the chemical and microbial characterization of the surface water of a CO 2 -rich hydrothermal vent known in Costa Rica as Borbollones,...

Why Archaea Are Limited in Their Exploitation of Other, Living Organisms
Only a handful of Archaea have been suggested to be connected with pathologies or to serve as parasites, and none conclusively. Here I consider what...
