Thioploca araucae
Description and significance
Thioploca araucae is a filamentous sulfur-oxidizing bacterium. It is typically found in bacterial mats in sediment layers at the bottom of the ocean. Thioploca has been found off the coast of Chile and Namibia, as well as in freshwater areas in Japan.
Genome structure
The genome is currently being sequenced by the J Craig Venter Institute.
Cell structure and metabolism
nitrate principal electron acceptor
link the sulfur and nitrogen cycles
Ecology
Thioploca cells form filaments that cling to each other and secrete an encompassing sheath of mucous film. The sheath serves as a kind of vertical tunnel through the sediment up to the overlying water, allowing the Thioploca filaments to glide up and down and thereby commute between their food source and the nitrate they need to metabolize it.
