Herpetosiphon aurantiacus DSM 785

The phylum Chloroflexi, which is divided into two orders, the Chloroflexales and the Herpetosiphonales, is a deep-branching lineage of the Bacteria. Members of the former order synthesize BChls and are obligately or facultatively phototrophic, while members of the latter order do not synthesize BChls and are not phototrophs. Although members of both groups are designated as Gram-negative, they do not synthesize lipopolysaccharide and thus do not possess outer membranes.Herpetosiphon aurantiacus ATCC 23779 was isolated from Birch Lake, Minnesota USA. It is an ensheathed, gliding bacterium; the sheathes move with the bacterium which is unflagellated. It divides by septum formation and does not contain chlorophyll. It is the type strain (adapted from PubMed 5669912 and 15340781). (HAMAP: HERA2)
