Calcite moonmilk of microbial origin in the Etruscan Tomba degli Scudi in Tarquinia, Italy [PDF]

, 2018
A white deposit covering the walls in the Stanza degli Scudi of the Tomba degli Scudi, Tarquinia, Italy, has been investigated. In this chamber, which is still preserved from any kind of intervention such as cleaning and sanitization, ancient Etruscans ...

Differential Colonization and Succession of Microbial Communities in Rock and Soil Substrates on a Maritime Antarctic Glacier Forefield

Frontiers in Microbiology, 2020
Glacier forefields provide a unique chronosequence to assess microbial or plant colonization and ecological succession on previously uncolonized substrates.

Statistical trends in culture methods of endolithic bacteria extracted from Quartz, K-Feldspar (Jurassic) and Calcite (Quaternary) in semi-arid areas in Colombia

Geologica Acta, 2022
Microbial endolithic communities are ubiquitous in many deserts around the globe. They have been found in many different lithologies, including quartz, plagioclase and calcite.

Geomicrobiology and Microbial Geochemistry [PDF]

, 2015
Geomicrobiology and microbial geochemistry (GMG) investigates the interaction between Earth, environmental systems, and microbial life. Microbes shape their geochemical surroundings through their metabolic and growth needs and thereby exert significant ...

Clay‐associated microbial communities and their relevance for a nuclear waste repository in the Opalinus Clay rock formation

MicrobiologyOpen, 2023
Microorganisms are known to be natural agents of biocorrosion and mineral transformation, thereby potentially affecting the safety of deep geological repositories used for high‐level nuclear waste storage.

On the pathways feeding the H₂ production process in nutrient-replete, hypoxic conditions : commentary on the article 'Low oxygen levels contribute to improve photohydrogen production in mixotrophic non-stressed Chlamydomonas cultures', by Jurado-Oller et al., Biotechnology for Biofuels, published September 7, 2015; 8:149 [PDF]

, 2017
Background: Under low O-2 concentration ( hypoxia) and low light, Chlamydomonas cells can produce H-2 gas in nutrient-replete conditions. This process is hindered by the presence of O-2, which inactivates the [FeFe]-hydrogenase enzyme responsible for H-2

Disguised as a Sulfate Reducer: Growth of the Deltaproteobacterium Desulfurivibrio alkaliphilus by Sulfide Oxidation with Nitrate

mBio, 2017
This study demonstrates that the deltaproteobacterium Desulfurivibrio alkaliphilus can grow chemolithotrophically by coupling sulfide oxidation to the dissimilatory reduction of nitrate and nitrite to ammonium.

Microbial turnover times in the deep seabed studied by amino acid racemization modelling

Scientific Reports, 2017
The study of active microbial populations in deep, energy-limited marine sediments has extended our knowledge of the limits of life on Earth. Typically, microbial activity in the deep biosphere is calculated by transport-reaction modelling of pore water ...

The Microbial Community and Functional Potential in the Midland Basin Reveal a Community Dominated by Both Thiosulfate and Sulfate-Reducing Microorganisms

Microbiology Spectrum, 2022
The Permian Basin is the highest producing oil and gas reservoir in the United States. Hydrocarbon resources in this region are often accessed by unconventional extraction methods, including horizontal drilling and hydraulic fracturing.

Geomicrobiology of the built environment [PDF]

, 2017
Microbial colonization and growth can have significant effects in the built environment, resulting in a range of effects from discolouration and staining to biodeterioration and decay.
