The Ectothiorhodospiraceae are a family of
purple sulfur bacteria, distinguished by producing sulfur globules outside of their cells.

flagella
A flagellum (; ) is a hairlike appendage that protrudes from certain plant and animal sperm cells, and from a wide range of microorganisms to provide motility. Many protists with flagella are termed as flagellates.

. 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. 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.
