Aphanocapsa sideroderma is a unicellular cyanobacterium forming colonial aggregates in gelatinous sheaths with iron-encrusted outer layers. It inhabits iron-rich freshwater environments including springs, streams, and wetlands. This photosynthetic bacterium produces energy through oxygenic photosynthesis and contributes to biofilm formation on iron-rich substrates.
