Accession numbers NC_011059, NC_011061
Background Prosthecochloris aestuarii is a non-motile, spherical to ovoid green sulfur bacterium that forms 10 to 20 non-branching prosthecae per cell (the function of these structures is unknown). It is anaerobic and obligately photoautotrophic in growth mode. Strain SK413 is the type species for the genus Prosthecochloris, and the organism was originally isolated from the hydrogen sulfide-rich mud of a shallow lagoon with elevated salt concentration and described in 1970. The cells produce bacteriochlorophyll c, bacteriochlorophyll a, and chlorophyll a as well as chlorobactene and its hydroxylated derivative as the major photosynthetic pigments. P.aestuarii can fix nitrogen, lacks gas vesicles, and has an elevated requirement for salt (range: 0.2 to 10% NaCl; optimum 0.5 to 2% NaCl) (adapted from http://genome.jgi-psf.org/finished_microbes/proae/proae.home.html).
