SUP05 bacteria are often found in places where there is really no basis for life for them. Researchers in Bremen have now discovered that they are even quite active there – possibly with consequences for the global nitrogen cycle. The bacteria travel with a “reserve pack”. In addition, the resear...

In a new study published by Nature, an international team of researchers led by Uppsala University in Sweden proposes a new evolutionary origin for mitochondria – also known as the ‘powerhouses of the cell’. Mitochondria are energy-converting organelles that have played key roles in the emergence...

Young scientists exploring the North Sea
Wind and waves, cries of seagulls, rain and occasionally a little bit of sunshine. That’s how we experience the North Sea at the beach walk. But what happens behind the beach in the sea? Children, youngsters and also adults can now find out with the onlin...
Scientists from Oldenburg, Bremen and Bremerhaven verify theory of the role of the South Pacific in natural atmospheric CO2 fluctuations.

Storing carbon dioxide (CO2) deep below the seabed is one way to counteract the increasing concentration of CO2 in the atmosphere. But what happens if such storage sites begin to leak and CO2 escapes through the seafloor? Answers to this question have now been provided by a study dealing with the...

„Den Bakterien mit Mikrosensoren auf der Spur“
Scientists have discovered that a ‘rare’ type of marine bacteria is much more widespread than previously thought – and possesses a remarkable metabolism that could contribute to greenhouse gas production.
Am 19. Oktober 2017 findet in München das Max-Planck-Forum in München statt. Nicole Dubilier, geschäftsführende Direktorin unseres Instituts, und Peter Fratzl, Direktor des Max-Planck-Instituts für Kolloid- und Grenzflächenforschung, sprechen darü...

Scientists from Germany and the USA have discovered deep-sea animals living in symbiosis with bacteria that use oil as an energy source. At asphalt volcanoes in the Gulf of Mexico that spew oil, gas and tar, mussels and sponges live in symbiosis with bacteria that use short-chained alkanes in the...
Daniel Globisch - "New biomarker discovery approaches for pancreatic cancer"
In freshwater lakes, large amounts of the greenhouse gas methane are oxidized by bacteria before it can be emitted into the atmosphere. A study in Lakes Rotsee and Zug has now shown that the bulk of this work is done, not by “classical” methane consumers, but by filamentous bacteria previously kn...

Microbes living under rapidly changing oxygen conditions can respire both oxygen and nitrate simultaneously. This way, they ensure that they can breathe at all times, even if they run out of oxygen.
On the 11th and 12th of May, some doctoral researchers from the Max Planck Institute for Marine Microbiologie and Max Planck Institute for Terrestrial Microbiologie met in Marburg for the first Max Planck Conference for Environmental Microbiology: "It MaTer(s)".
The prize promotes the compatibility of science and family.
From burning hot to ice cold, from energy-rich to an exhausted desert - environmental conditions at deep-sea hot vents change dramatically at very small scales. Nevertheless, resident bacteria know exactly what they like best. Each one has their own ecological niche.

Consider a snow globe. When shaken, the tiny flakes and particles are set into motion and “it snows”. What lights up kid’s eyes has been a long standing puzzle for scientists.
Two new studies present exciting details on seafloor bacterial life in the North Sea.

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
Periodic oscillations of bottom-water oxygen concentrations can alter benthic communities and carbon storage for decades, reveals a new study published in Science Advances. This is particularly relevant as low oxygen conditions are on the rise in the world’s oceans.
The deep sea is a vast and seemingly uninhabitable place, except for some small oases of life. Sunken wood logs, so-called wood falls, can form such oases and provide for rich life for limited periods. A new study by researchers from the MPI Bremen takes a close look at the deep-sea organisms inh...

Researchers from the Max Planck Institute for Marine Microbiology in Bremen and their colleagues from the Helmholtz-Zentrum für Umweltforschung (UFZ) in Leipzig discovered microbial communities thriving on the hydrocarbon butane without the help of molecular oxygen.

A study published in Nature Microbiology shows for the first time that a small nitrogen-fixing symbiosis contributes extensively to the total nitrogen fixation in the tropical North Atlantic. Nitrogen fixation is the largest source of nitrogen to the open ocean, and this symbiosis is thus a key p...
At the margins of oxygen minimum zones (OMZs) at ultralow oxygen concentrations, aerobic ammonium and nitrite oxidizers compete for nitrogen with anaerobic microorganisms. Thus they play an important but so far overlooked role in controlling nitrogen loss in OMZs.
Tropical Porites corals adjust their internal pH to enable themselves to form calcium carbonate and grow under elevated carbon dioxide concentrations – even for a longer period of time. New investigations reveal that the corals’ adaptability has its limits.
Hydrothermal vents in the deep sea are hundreds and thousands of kilometers apart and their inhabitants are isolated and not directly connected to each other. And yet there is clearly some sort of exchange between individual vents as similar species can be found at vents that are very far apart f...
Climate change has focused attention on burgeoning oxygen minimum zones. Newly discovered SAR11 bacteria deplete nitrogen, essential life nutrient.

Scientists from Montana State University and MPI Bremen show how the spatial organisation of microbes leads to an efficient transfer of nutrient...
Day in, day out, in the smallest of spaces with your greatest enemy. Sounds unbearable? In the world of microbes, this has been everyday life for billions of years.

Invitation to the MPI Seminar
We cordially invite you to join an exciting talk of the american scientist Mitchell L. Sogin from Josephine Bay Paul Center, Marine Biological Laboratory (Woods Hole, USA) on Monday, May 30.
No two bacteria are identical – even when they are genetically the same. A new study reveals the conditions under which bacteria become individualists and how they help their group grow when times get tough.
An international research team around director Nicole Dubilier are on their way to investigate the life around hydrothermal vents on the Mid-Atlantic Ridge. A videoblog provides exciting details from board.

Every spring, algae bloom in the North Sea. In these blooms, different algae can come out on top each year. Nevertheless, within the bacteria subsequently degrading the algae, the same specialised groups prevail year after year.
If your favourite pub moves – would you move too or look for another pub? For bacteria living in symbiosis with marine worms it all depends on whether they sit outside or inside the pub. Scientifically speaking: bacteria living on the body surface of their hosts are loyal to those, while bacteria...
Imagine you have a tenant living in your house. They’re keeping your fridge topped up. But in addition to this, they’re producing all kinds of toxic substances. More harm than good? Not necessarily; it all depends what you’re using the toxins for.
