Viele unserer wichtigsten Medikamente, allen voran Antibiotika, verdanken wir Stoffen, die Bakterien in der Natur produzieren. Sie nutzen diese Moleküle als biochemische Waffen gegen Konkurrenten oder um Nährstoffe aus ihrer Umgebung zu binden. Wie groß dieser mikrobielle Werkzeugkasten selbst unter schwierigen Umweltbedingungen ist, zeigt eine neue Studie. Ein Forschungsteam des Exzellenzclusters „Balance of the Microverse“ der Universität Jena,… Continue reading

Researchers at the University of Bern, in collaboration with scientists from Australia and New Zealand, have recreated a significant process in the laboratory that enables organisms to extract energy directly from the air. This confirms that certain organisms, such as bacteria, can indeed live on air alone, without relying on sunlight or other energy sources. The findings open up new possibilities… Read more »

An interdisciplinary research team led by the Leibniz-HKI in Jena has discovered a new group of bioactive natural products in pathogenic bacteria of the genus Pandoraea: pandorabactins. These enable the bacteria to extract vital iron from other microorganisms and can thus influence the microbial balance in the human lungs. Bacteria of the genus Pandoraea have so far been little studied. Their… Read more »

Microbes on sand grains: Tiny helpers in the fight against nitrogen pollution

Bremen, June 03, 2025 – Microorganisms on sand grains in oxygen-rich coastal waters play a surprising role in nitrogen reduction: Some microbes consume all the oxygen in their environment, creating tiny oxygen-free zones where their neighbors break down nitrate through denitrification. This is shown by a new study from the Max Planck Institute for Marine Microbiology in Bremen, published in… Continue reading

Slow-growing bacteria are more sensitive to their environment

Bacteria have a simple yet effective mechanism that controls how sensitive they are to environmental stimuli. A research team at the University of Basel has shown that the cells' responsiveness is directly related to their growth rate: the slower a cell grows, the more sensitive it is to its environment. This heightened sensitivity can give the cells a crucial survival advantage. The research group led by Prof. Dr.… Read more »

Bacteria control the reproduction of jellyfish

Microbiologists at Kiel University have demonstrated that the asexual reproduction of the moon jellyfish is largely controlled by bacterial products. Beta-carotene, produced by microbes in the jellyfish's natural microbiome, plays a key role in this process. Without these microorganisms, the so-called strobilation process—the transformation of the polyp into young medusae—comes to a standstill. This results in developmental disorders… Read more »

In the desert regions of Namibia, Oman, and Saudi Arabia, research has revealed unusual phenomena likely caused by an unknown microbiological life form: Unusually small holes – tiny tubes running parallel through the rock from top to bottom – have been discovered in the marble and limestone of these desert regions. “We were surprised because these tubes are apparently not… Read more »

A new study published in PLOS Genetics has identified an extreme mutation hotspot in the genome of Pseudomonas fluorescens, providing unprecedented insights into the relationship between gene regulation and mutation rates. The findings could have far-reaching implications for understanding bacterial evolution, adaptation, and antibiotic resistance. The research by Andrew D. Farr, Christina Vasileiou, Peter A. Lind, and Paul B. Rainey shows… Read more »

A modular metabolism could explain the success of certain sulfate-reducing bacteria. The researchers studied members of a bacterial family that are highly active in anaerobic sediments. All species studied share the same core elements in their metabolism. Depending on the species, additional proteins are added to utilize specific organic substances. The results could help clarify the role... Continue reading

Microbiome at the root: Bacteria successfully suppress the plant's immune system

Researchers at the Max Planck Institute for Plant Breeding Research in Cologne have shown that many bacteria living on healthy plant roots can suppress the plants' immune responses. Immunosuppression protects bacterial communities on roots, the so-called root microbiota, from the influence of the plant's immune system. The plant immune system is a highly specialized and sensitive defense system designed to ward off pathogenic microbes. Therefore… Continue reading
