Looking for deadly snake bacteria in Norway and Sweden
Using scalpels and cotton swabs, researchers take tissue samples from the snake to look for traces of the deadly fungus. Credit: Agder University Researchers at Agder University (UIA) and Uppsala University are examining hundreds of snakes in the museum collection. They are looking for traces of a fatal fungal disease. The goal is to understand more about Ophidiomyces ophidiicola, as…

Oxygen-Stable Biocatalysts from Thermophilic Bacteria Can Increase Hydrogen Production
Credit: Journal of the American Chemical Society (2025). doi: 10.1021/jacs.4c18483 In the absence of air, microorganisms use an enzyme called (FEFE)-hydrogenase to produce hydrogen. However, these enzymes are rapidly destroyed when exposed to air. Currently, a joint effort led by scientists and theoretical chemistry centers at Ruhr University Bochum, Germany, has isolated a new type of oxygen stability (FEFE)-hydrogenase and…

Strategic genetic placement in bacteria provides insight into evolutionary success
During bacterial chromosome replication, multiple copies have genes close to the replication start point (red) and no genes close to the endpoint (blue). Fastest growth will result in stronger effects, reading genes close to the start point simultaneously from up to eight gene copies, resulting in higher expression levels. Depending on how the demand for expression of a particular gene…

1 Trillion Species, 3 Billion Years: How to Track the Evolution of Bacteria on Earth using AI
Credit: CC0 Public Domain There are about 1 trillion species of microorganisms on Earth. Most of it is bacteria. Bacteria are made up of a single cell. They have no bones and are not like large animals that leave clear signs in the geological records. This is something paleontologists who appreciate it in a few million years can study. This…

Earth’s hidden carbon recycling: Sulfur bacteria work together to break down organic matter from the seabed
To determine the molecular tools sulfate-reducing bacteria use, researchers analyzed the entire set of proteins known as the proteome. In total, they looked at the results of 80 different test conditions. Each time, the protein mixture was separated in several steps until individual compounds were identified. Here, a separation gel containing a blue band with proteins of similar size and…

Arsenic Detoxification: How Bacteria and Minerals Work
Synergistic mechanism of arsenic detoxification by getite and arsenic oxidizing bacteria (SY8). This diagram illustrates the synergistic mechanisms by which Goethite (GOE) and arsenic-oxidizing bacteria (SY8) promote arsenic detoxification. Bacteria oxidizes toxic arsenite (AS(III)) and oxidizes to less harmful arsenite (As(v)). This is amplified by the catalytic effect of Goethite. The interaction between bacteria and getite promotes the formation of…

Marine particle bacteria play an important role in the marine nitrogen cycle
Ocean snow is made up of various biological fragments in the water column. The photo shows ocean snow from the Sargasso Sea. Credit: L. Lehman Whether living bacteria from organic matter dissolved in seawater can carry out N2 fixation, and how bacteria have confusing scientists. High levels of oxygen combined with the amount of dissolved organic matter in the seawater…
