Microbes are intimately involved in the iron cycle. First, acquisition of iron by microorganisms
for biochemical requirements is a key process in the iron cycle in oxygenated, circumneutral …

Iron (Fe) has long been a recognized physiological requirement for life, yet for many
microorganisms that persist in water, soils and sediments, its role extends well beyond that …

Iron is the most abundant redox‐active metal in the Earth's crust. The one electron transfer
between the two most common redox states, Fe (II) and Fe (III), plays a role in a huge range …

Preface. Iron is considered to be a minor element employed, in a variety of forms, by nearly
all living organisms. In some cases, it is utilised in large quantities, for instance for the …

Iron cycling in the Earth's crust depends on redox reactions, which often trigger the
precipitation and dissolution of Fe-rich minerals. Microbial activity is also an integral part of …

Iron is the most abundant element on Earth and the most frequently utilized transition metal
in the biosphere. It is a component of many cellular compounds and is involved in numerous …

Iron is a ubiquitous element in the universe. Ferrous iron (Fe (II)) was abundant in the
primordial ocean until the oxygenation of the Earth's atmosphere led to its widespread …

Bacteriogenic iron oxides (BIOS) are composite materials that consist of intact and partly
degraded remains of bacterial cells intermixed with variable amounts of poorly ordered …

the ferric (Fe (lll) J state. Much of the Fe (lll) that is available for microbial metabolism is in
the form of poorly crystalline Fe (N) oxides that typically exist as coatings on clays and other …

Iron is a metabolic requirement of living systems, yet iron is very insoluble in aerobic, neutral
environments. Therefore, the amount of iron in solution under these conditions is not …
