Caption: Cyanidium caldarium alga. Coloured transmission electron micrograph (TEM) of a section through an extremophile Cyanidium caldarium alga. Three chloroplasts are seen here (blue/green), each showing layered bands (blue) of photosynthetic pigment. This species is classified under the red algae, but has mainly blue pigmentation. Cyanidium caldarium lives in hot, acidic pools and soil, usually around hot springs. It is an acidophile, and can withstand acidity around pH 0, very rare in a living organism. Its optimum growth temperature is around 50 degrees Celsius. Magnification: x8000 at 6x6cm size.
