Laboratory Activity to Effectively Teach Introductory Geomicrobiology Concepts to Non-Geology Majors

Journal of Microbiology & Biology Education, 2013
We have designed a three-week experiment that can complement any microbiology course, to teach main geomicrobiology concepts for non-geology majors.

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.

Marine Deep Biosphere Microbial Communities Assemble in Near-Surface Sediments in Aarhus Bay

Frontiers in Microbiology, 2019
Analyses of microbial diversity in marine sediments have identified a core set of taxa unique to the marine deep biosphere. Previous studies have suggested that these specialized communities are shaped by processes in the surface seabed, in particular ...

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.

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.

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.

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.

From Plant to Paddy—How Rice Root Iron Plaque Can Affect the Paddy Field Iron Cycling

Soil Systems, 2020
Iron plaque on rice roots represents a sink and source of iron in paddy fields. However, the extent of iron plaque in impacting paddy field iron cycling is not yet fully deciphered.
