The Ectothiorhodospiraceae are a family of
purple sulfur bacteria
The purple sulfur bacteria (PSB) are part of a group of Pseudomonadota capable of photosynthesis, collectively referred to as purple bacteria. They are anaerobic or microaerophilic, and are often found in stratified water environments including ...
, distinguished by producing sulfur globules outside of their cells.
[George M. Garrity: '' Bergey's Manual of Systematic Bacteriology''. 2. Auflage. Springer, New York, 2005, Volume 2: ''The Proteobacteria, Part B: The Gammaproteobacteria''] The cells are rod-shaped, vibrioid, or spirilla, and they are able to move using
flagella. In general, they are marine and prefer anaerobic conditions.
Ectothiorhodospiraceae are a vibrio bacteria that require salty living conditions to survive and grow: classifying them as slightly halophilic.
Like all purple sulfur bacteria, they are capable of
photosynthesis
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemical energy is stored i ...
. To complete this energy process, Sulfur compounds are used as electron donors for carbon fixation in the pentose phosphate pathway.
This elemental sulfur accumulates outside of the cells.
