Iron‐Bearing Minerals as Potential Indicators of Paleo‐Methane Seepage Evolution

Journal of Geophysical Research: Oceans, Volume 130, Issue 10, October 2025.
Abstract Methane (CH4) release and consumption in marine cold seeps are key processes influencing seabed ecology, global climate reconstruction, and hydrate resource exploration. Anaerobic oxidation of methane (AOM), the primary methane consumption mechanism, typically couples with microbial sulfate or metal reduction.

Formate, acetate and propionate as substrates for sulfate reduction in sub-arctic sediments of Southwest Greenland.

Frontiers in Microbiology, 2015
Volatile fatty acids (VFAs) are key intermediates in the anaerobic mineralization of organic matter in marine sediments. We studied the role of VFAs in the carbon and energy turnover in the sulfate reduction zone of sediments from the sub-arctic ...

A role for microbial selection in frescoes' deterioration in Tomba degli Scudi in Tarquinia, Italy [PDF]

, 2017
Mural paintings in the hypogeal environment of the Tomba degli Scudi in Tarquinia, Italy, show a quite dramatic condition: the plaster mortar lost his cohesion and a white layer coating is spread over almost all the wall surfaces.

Interactions between magnetite and humic substances: redox reactions and dissolution processes

Geochemical Transactions, 2017
Humic substances (HS) are redox-active compounds that are ubiquitous in the environment and can serve as electron shuttles during microbial Fe(III) reduction thus reducing a variety of Fe(III) minerals.

Temperature effects on the strengh properties of microbially stabilized residual soil [PDF]

, 2016
Microbially Induced Calcite Precipitation (MICP) is a rather new technology that has shown greater potential in geotechnical engineering applications. The technique utilizes the concept of microbial involvements in carbonate precipitation within the soil

Metatranscriptomics of microbial biofilm succession on HDPE foil: uncovering plastic-degrading potential in soil communities

Environmental Microbiome
Background Although plastic pollution is increasing worldwide, very little is known about the microbial processes that take place once plastic debris is incorporated into the soil matrix.
