Jannaschia sp. CCS1

Ecology and Physiology

Jannaschia sp. CCS1 is a member of the Roseobacter lineage (α-Proteobacteria), an ecologically relevant taxon of marine bacteria abundant in coastal and open ocean surface waters. CCS1 is an aerobic anoxygenic phototroph (AAnP), using bacteriochlorophyll a to harvest energy from light without formation of oxygen. AAnPs have recently been found in ocean surface waters, where they make up a significant fraction of the marine bacterioplankton community, are responsible for a share of the oceanic photosynthetic electron transport flux, and have important implications for the ocean carbon cycle.

Jannaschia sp. CCS1 was isolated from Pacific coastal waters on low-nutrient seawater medium. It is motile, grows slowly, and like other marine AAnPs, produces bacteriochlorophyll a when grown in the dark.
