Cyanocatena imperfecta is a type of cyanobacteria that typically forms chains or filaments of cylindrical cells connected end-to-end, resembling beads on a string. Each cell is surrounded by a mucilaginous sheath, a common trait among cyanobacteria. These cells are generally small and vary in size depending on their environment. Found in freshwater habitats like lakes, ponds, and slow-moving streams, Cyanocatena imperfecta contributes to aquatic ecosystems through processes such as photosynthesis and nitrogen fixation, playing important roles in nutrient cycling and ecosystem health.
