     Herpetosiphon The Chloroflexi are a group of bacteria that produce energy through photosynthesis. They make up the bulk of the green non-sulfur bacteria, though some are classified separately as the Thermomicrobia. They are named for their green pigment, usually found in photosynthetic bodies called chlorosomes .

Chloroflexi are typically filamentous, and can move about through bacterial gliding. They are facultatively aerobic, but do not produce oxygen during photosynthesis, and have a different method of carbon fixation than other photosynthetic bacteria. Genetic trees indicate that they had a separate origin.
