Description and Significance

Galdieria sulphuraria is a eukaryotic, spore-forming, coccus. G. sulphuraria appears yellow-green to dark blue-green grown heterotrophically in liquid culture, and often yellow or green in its natural environment. It is an acidophile, as well a thermophile, and inhabits highly acidic springs at high temperatures.

G. sulphuraria is a mixotrophic organism capable of both photosynthesis and the catabolism of a wide variety of metabolites.

Genome Structure

"At least 5% of protein-coding genes of G. sulphuraria were probably acquired horizontally." [1]
