Anathece bachmannii is a freshwater cyanobacterium characterized by its cylindrical cells, often forming short, unbranched filaments. Enclosed within a mucilaginous sheath, these cells display colors varying from greenish-blue to brownish. In aquatic environments, Anathece bachmannii contributes significantly through photosynthesis and nitrogen fixation, processes essential for nutrient dynamics and the sustenance of freshwater ecosystems’ biodiversity and productivity.
