The Ectothiorhodospiraceae are a family of purple sulfur bacteria, distinguished by producing sulfur globules outside of their cells.[4] 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.[4] Ectothiorhodospiraceae are a vibrio bacteria that require salty living conditions to survive and grow: classifying them as slightly halophilic.[4] Like all purple sulfur bacteria, they are capable of photosynthesis. To complete this energy process, Sulfur compounds are used as electron donors for carbon fixation in the pentose phosphate pathway.[4] This elemental sulfur accumulates outside of the cells.[4]
