Bacteria in the Arctic seabed are active all year round

The bacterial community in Arctic sediments is taxonomically and functionally very stable more

Infinite vastness: Gases are constantly exchanged between the ocean and the atmosphere. The study presented here shows how tiny marine organisms contribute significantly to the release of the greenhouse gas methane in the tropical Atlantic.

Off Barbados, researchers have investigated how bacteria inadvertently release methane in order to obtain phosphorus more

Wastewater tank

In a long-term culture, scientists find two new microorganisms growing on the toxic gas nitric oxide more

Microorganisms break down petroleum components in the seabed

Archaea cultivated in the laboratory are active even at high temperatures and without oxygen more

Marine bacteria duplicate at different rates

Study challenges dogmas about marine microbial life more

Reviving Stone Age molecules

Scientists are rebuilding microbial natural products up to 100,000 years old using dental calculus of humans and Neanderthals more

Reactive oxygen impacts carbon cycling in tidal sands

Scientists detect high concentrations of hydrogen peroxide in intertidal sands more

Life in the smoke of underwater volcanoes

The plumes from hydrothermal vents provide an ecological link between the open ocean and the seafloor more

Enzyme of bacterial origin promoted the evolution of longhorned beetles

Gene duplication increased the diversity and specificity of enzymes that enable beetle larvae to degrade important wood components more

Seagrass meadows

Researchers have discovered vast amounts of sugars underneath seagrass meadows more

All organisms produce methane

The formation of the greenhouse gas is driven by reactive oxygen species more

From the oilfield to the lab

A special microbe turns oil into gases all by itself more

A natural CO<sub>2</sub>-sink thanks to symbiotic bacteria

Like many land plants, seagrasses live in symbiosis with nitrogen-fixing bacteria more

The viruses of the North Sea

Viruses in the ocean are numerous, diverse and play an important role in the marine carbon cycle more

A long day for microbes

A slowdown in the Earth's rotation could have affected the oxygen content of the atmosphere more

Small “snowflakes” in the sea play a big role

New findings from scientists of Bremen will aid in the further development of biogeochemical models that include the marine nitrogen cycle more

Every grain of sand is a met­ro­polis for bac­teria

A single sand grain harbours up to 100,000 microorganisms from thousands of species. more

Oil as energy source for deep-sea creatures

Scientists discover mussels and sponges in the deep sea which can thrive on oil with the help of symbiont bacteria more

Getting to the bottom of the deep sea

Antje Boetius from the Max Planck Institute for Marine Microbiology in Bremen always has multiple objectives in her sights: from discovery and precautionary research to technological development and scientific communication. more

Oil degradation without oxygen

Some bacteria do not require oxygen to degrade crude oil. They can survive even deep within the ocean's sedimentary layers more
