Iron (Fe) is the fourth most abundant element in the earth's crust and plays important roles in
both biological and chemical processes. The redox reactivity of various Fe (II) forms has …

Microbial-induced calcium carbonate precipitation (MICP) is a technique that uses the
metabolic action of microorganisms to produce CO 3 2− which combines with free Ca 2+ to …

Vanadium (V) is a redox-sensitive heavy-metal contaminant whose environmental mobility is
strongly influenced by pyrrhotite, a widely distributed iron sulfide mineral. However …

Sulfate/sulfite-reducing microorganisms (SRM) are ubiquitous in nature, driving the global
sulfur cycle. A hallmark of SRM is the dissimilatory sulfite reductase encoded by the genes …

Microbe‐mediated mineralization is ubiquitous in nature, involving bacteria, fungi, viruses,
and algae. These mineralization processes comprise calcification, silicification, and iron …

Microorganisms play a key role in the natural circulation of various constituent elements of
metal sulfides. Some microorganisms (such as Thiobacillus ferrooxidans) can promote the …

Micro-organisms contribute to Earth's mineral deposits through a process known as bacteria-
induced mineral precipitation (BIMP). It is a complex phenomenon that can occur as a result …

The exergonic reaction of FeS with H2S to form FeS2 (pyrite) and H2 was postulated to have
operated as an early form of energy metabolism on primordial Earth. Since the Archean …

Our demand for electronic goods and fossil fuels has challenged our ecosystem with
contaminating amounts of heavy metals, causing numerous water sources to become …

In this study, quartz substrates were incubated in sulfate-reducing bacteria (SRB) culture for
21 days at room temperature. Fourier transform infrared spectroscopy (FTIR) and scanning …
