Giant sulfur bacteria

Filaments of two different species, Thioploca chileae (18 – 20 µm Ø) and
Thioploca araucae (31 – 35 µm Ø) in the same sheath.
Sometimes different sulfur bacteria can be found in the same sheath. Typical are the sulfur droplets in the cytoplasm, which arise from the first step of H2S oxidation.
