Importantly, 189 partial or complete 4-hydroxybutyryl-CoA dehydratase gene sequences were found after searching the Global Ocean Sampling dataset; mesophilic marine archaea that fix carbon by this ...

A recent study has shown that they also have the potential to fix inorganic carbon—in the form of carbon dioxide (CO2)— to generate acetate, an important fuel for other sediment-dwelling organisms ...

Life in these underworlds runs on a very different timeline to Earth's bustling surface. With no sunlight, energy is sparse ...

At the level of individual samples, subsurface archaea were most diverse in brines, caves, cold seeps, springs, and the deep sea. Subsurface bacteria were most diverse in caves and marine ...

In the mid-1990s, scientists made a discovery that shook up the understanding of life on Earth: vast reservoirs of microbes ...

Marine biology is the study of life in the oceans and brackish waters, which ranges from archaea and bacteria to marine mammals, and includes organisms such as corals that affect the shape of the ...

“This should have a major effect on textbook treatment of these subjects.” Since the late 1980s, all life forms have been split into three groups on the phylogenetic tree of life: bacteria, archaea, ...
