Recreating ancient minerals

When it comes to making a lasting impression in geological history, the medium makes all the difference, especially in the Earth's paleo-oceans. Here, during the Archean Eon (4,000-2,500 million years ago) and at times during ...

From a plant sugar to toxic hydrogen sulfide

In a doctoral research project conducted at the Department of Biology, researchers have described the degradation of the dietary sugar sulfoquinovose by anaerobic bacteria to toxic hydrogen sulfide for the first time—increased ...

Biochar could benefit anaerobic digestion of animal manure

New research by Texas A&M AgriLife Research scientists shows biochar has potential to make anaerobic digestion of animal manure a more efficient method to rid farms of waste while producing methane for energy.

Microbes corrode steel in ships, marine infrastructure

Rust is the bane of steel, whether on cars, on ships and boats, or as part of marine infrastructure. Now, contrary to previous thinking, it turns out that the ocean-dwelling, steel-corroding species, Mariprofundus sp. DIS-1, ...

Starved-out bacteria aid in wastewater treatment

Scientists have adapted a process normally used to make bioplastic, to remove carbon from wastewater, slashing the amount of energy needed for the treatment process.

Methane oxidation fuelled by algal oxygen production

Methane emissions are strongly reduced in lakes with anoxic bottom waters. But here – contrary to what has previously been assumed – methane removal is not due to archaea or anaerobic bacteria. A new study on Lake Cadagno ...
