Anoxic and iron-rich (ferruginous) conditions prevailed in the ocean under the low-oxygen
atmosphere that occurred through most of the Archean Eon. While euxinic conditions (ie …

The review deals with systematization and generalization of new information concerning the
phylogenetic and functional diversity of prokaryotes involved in the methane cycle. Methane …

Oxygenic photosynthesis supplies organic carbon to the modern biosphere, but it is
uncertain when this metabolism originated. It has previously been proposed, that …

Photoferrotrophy, the process by which inorganic carbon is fixed into organic matter using
light as an energy source and reduced iron [Fe (II)] as an electron donor, has been proposed …

Anoxygenic photoautotrophic metabolism of green sulfur bacteria of the family
Chlorobiaceae played a significant role in establishing the Earth's biosphere. Two known …

Anaerobic oxidation of methane (AOM) is one of the major processes of oxidizing methane
in marine sediments. Up to now, extensive studies about AOM coupled to sulfate reduction …

Hydrogen sulfide (H 2 S) produced by biofilms and sediments in sewer systems causes
severe odor and corrosion problems, resulting in billions of dollars loss annually in the …

The gas hydrate‐bearing structure—mud volcano Kedr‐1 (Lake Baikal, southern basin)—is
located near the coal‐bearing sediments of the Tankhoy formation of Oligocene–Miocene …

Decomposing cyanobacterial bloom-induced black blooms been seen as an issue in the
management of freshwater ecosystems, but its effect on sulfate-reducing bacteria (SRB) in …

To elucidate the role of (bio) geochemical processes that fueled iron and carbon cycling in
early Earth oceans, modern environments with similar geochemical conditions are needed …
