Vagabonds and homebodies: Niches of bacterial life in the seabed

Oct 11, 2024

In the ocean‘s sandy seafloor, bacterial residents have neatly organized their housing space.

From the very small to the big picture: A new era in microbiology

Sep 19, 2024

Microbes were the only life form on Earth for most of the history of our planet. Even today, they still make up the majority of species that are vital to the health of our planet. They produce much of our oxygen, help plants grow, maintain biogeochemical cycles and thus sustain our ecosystems. A....

Making sugars in the lab to understand how algae capture carbon

Jun 27, 2024

Fucoidan, a sugar released by algae, can trap carbon dioxide (CO2) for centuries but remains poorly understood due to its complex and diverse molecular structure. Dr. Conor Crawford developed an automated method to recreate fucoidan to study which types are most effective at storing carbon. With ...

Breathing poison: Microbial life on nitric oxide respiration

Jul 10, 2023

Nitric oxide (NO) is a central molecule in the global cycling of nitrogen, and also toxic. Little is known about if and how microbes can use NO as a substrate for growth. Scientists from the Max Planck Institute for Marine Microbiology in Bremen, Germany, have now managed to grow a microbial comm...

What you count is not necessarily what counts

May 22, 2023

Seawater is full of bacteria, hundreds of thousands live in every litre. But the sheer number of bacteria living in the water does not necessarily mean a lot. More important is how active they are and how quickly they duplicate, as demonstrated in a study by researchers from the Max Planck Instit...

An Ocean of tiny wonders

May 15, 2023

Algal blooms in the ocean play a pivotal role in global carbon cycling. Such blooms entail successive blooms of specialized bacteria that collectively remineralize gigatons of algal biomass on a global scale. This biomass is largely composed of distinct polysaccharides, and the microbial decompos...

Life in the smoke of underwater volcanoes

Mar 9, 2023

Disconnected from the energy of the sun, the permanently ice-covered Arctic deep sea receives miniscule amounts of organic matter that sustains life. Bacteria which can harvest the energy released from submarine hydrothermal sources could thus have an advantage. On research missions with the rese...

Slime for the climate, delivered by brown algae

Dec 26, 2022

Brown algae take up large amounts of carbon dioxide from the air and release parts of the carbon contained therein back into the environment in mucous form. This mucus is hard to break down for other ocean inhabitants, thus the carbon is removed from the atmosphere for a long time, as researchers...
