#cyanobacterium — Public Fediverse posts

#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."

The #freshwater #cyanobacterium #Aetokthonos hydrillicola produces highly #toxic dolastatin derivatives https://www.pnas.org/doi/10.1073/pnas.2219230120

"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."
