Advanced genetic techniques and microscopy offer new insights into anaerobic ciliate and methanogen symbiosis

A recent study has uncovered critical details about the association between anaerobic ciliates and methanogenic archaea, a relationship that has fascinated scientists for over decades. Researchers from the Faculty of Science, Charles University, and University of Rhode Island have used advanced genetic techniques and microscopy to study this relationship in 32 species of free-living anaerobic ciliates, primarily from the order Metopida.

Scientists publish first experimental evidence for new groups of methane-producing organisms

A team of scientists from Montana State University has provided the first experimental evidence that two new groups of microbes thriving in thermal features in Yellowstone National Park produce methane—a discovery that could one day contribute to the development of methods to mitigate climate change and provide insight into potential life elsewhere in our solar system.

Scientists unravel symbiotic secrets of prokaryotic community living in host amoeba

In a new study, researchers from the Faculty of Science of Charles University, in collaboration with researchers from Max-Planck Institute for Terrestrial Microbiology and European Molecular Biology Laboratory from Heidelberg, have delved into the intricate partnership between anaerobic amoebae from the genus Pelomyxa and their prokaryotic companions. Pelomyxa, known for their unique symbiotic relationships with multiple prokaryotic endosymbionts, has long mystified scientists regarding the role these symbionts play in their host's metabolism.

Ancient lake microbes caused global warming during ice age

Global warming is not just a modern issue, but has occurred numerous times over Earth's history, with one such event happening 304 million years ago during the Late Paleozoic Ice Age (which spanned from 340 to 290 million years ago). Studies have discovered evidence of increased sea surface temperature, continental ice decline and oceanic environments flooding the land at the time.
