#ZARM scientists have identified the #cyanobacterium strain Anabaena sp. PCC 7938 as a highly promising one for a life support system on #Mars 🔴. Fed with a simulant of Martian dust and atmosphere, the selected strain demostrated its ability to produce oxygen and form biomass, which could serve the production of food 🥔, fuels, drugs 💊 and other materials https://www.zarm.uni-bremen.de/en/in-focus/space-exploration

"Citrate synthase from S. elongatus has the peculiar capacity to self-assemble into a type of #fractal shape known as a #Sierpiński triangle. This is not a universal feature of citrate synthases, there's something unique about the one from this #cyanobacterium."

How a cyanobacterium manages iron scarcity makes it the most successful photosynthetic organism on Earth
The sea is the world's largest ecosystem, and it harbors two photosynthetic organisms that produce approximately half of the oxygen on Earth. The cyanobacterium Prochlorococcus is the most abundant photosynthetic organism in the oceans and fixes approximately 4 gigatons of carbon each year, comparable to the net global primary production of the world's agriculture industry.
Altered light-harvesting complex in a cyanobacterium allows low-energy light use
Researchers have isolated and determined the molecular structure of the light-harvesting antenna that helps some cyanobacteria—formerly referred to as blue-green algae—produce energy through photosynthesis even in lower-energy light.
Two years ago, the same team established that the first toxin from the

Double Trouble: Infamous “Eagle Killer” Bacterium Produces Not One, But Two Toxins
Aetokthonos hydrillicola is particularly challenging for researchers.

"Even in low concentrations, this #toxin can destroy cells and is similar to substances currently used in cancer treatment. Two years ago, the same team established that the first toxin from the cyanobacterium is the cause of a mysterious disease among #BaldEagles in the USA."
Double trouble: Infamous 'eagle killer' bacterium produces not one, but two toxins
The cyanobacterium Aetokthonos hydrillicola produces not just one, but two highly potent toxins. In the latest issue of the journal Proceedings of the National Academy of Sciences (PNAS), an international team led by Martin Luther University Halle-Wittenberg (MLU) and Freie Universität Berlin describes the second toxin, which had remained elusive until now.
