For many decades, Escherichia coli was the main model organism for the study of bacterial
membrane lipids. The results obtained served as a blueprint for membrane lipid …

Microbial biofilms are formed by adherence of the bacteria through their secreted polymer
matrices. The major constituents of the polymer matrices are extracellular DNAs, proteins …

The microorganism-microorganism or microorganism-host interactions are the key strategy
to colonize and establish in a variety of different environments. These interactions involve all …

Acid mine drainage (AMD) emplacements are low-complexity natural systems. Low-pH
conditions appear to be the main factor underlying the limited diversity of the microbial …

Background Soil contaminated with the heavy metal Cadmium (Cd) is a widespread
problem in many parts of the world. Based on metagenomic analysis, we investigated the …

Sulfur oxidation is an essential component of the earth's sulfur cycle. Acidithiobacillus spp.
can oxidize various reduced inorganic sulfur compounds (RISCs) with high efficiency to …

High-throughput sequencing is expanding our knowledge of microbial diversity in the
environment. Still, understanding the metabolic potentials and ecological roles of rare and …

Caves are typified by their permanent darkness and a shortage of nutrients. Consequently,
bacteria play an important role in sustaining such subsurface ecosystems by dominating …

Life on Earth is limited by physical and chemical extremes that define the 'habitable
space'within which it operates. Aside from its requirement for liquid water, no definite limits …

In soluble rocks such as limestone and dolostone there are two main types of cave genesis
(speleogenesis);(i) epigenic speleogenesis, in which the aggressiveness that forms caves is …
