Bottom Line: H. aurantiacus cells are organized in filaments which can rapidly glide.The species is of interest not only because of its rather isolated position in the tree of life, but also because Herpetosiphon ssp. were identified as predators capable of facultative predation by a wolf pack strategy and of degrading the prey organisms by excreted hydrolytic enzymes.The 6,346,587 bp long chromosome and the two 339,639 bp and 99,204 bp long plasmids with a total of 5,577 protein-coding and 77 RNA genes was sequenced as part of the DOE Joint Genome Institute Program DOEM 2005.

ABSTRACT
Herpetosiphon aurantiacus Holt and Lewin 1968 is the type species of the genus Herpetosiphon, which in turn is the type genus of the family Herpetosiphonaceae, type family of the order Herpetosiphonales in the phylum Chloroflexi. H. aurantiacus cells are organized in filaments which can rapidly glide. The species is of interest not only because of its rather isolated position in the tree of life, but also because Herpetosiphon ssp. were identified as predators capable of facultative predation by a wolf pack strategy and of degrading the prey organisms by excreted hydrolytic enzymes. The genome of H. aurantiacus strain 114-95(T) is the first completely sequenced genome of a member of the family Herpetosiphonaceae. The 6,346,587 bp long chromosome and the two 339,639 bp and 99,204 bp long plasmids with a total of 5,577 protein-coding and 77 RNA genes was sequenced as part of the DOE Joint Genome Institute Program DOEM 2005.

f2: Scanning electron micrograph of a multicellular filament of H. aurantiacus 114-95T.

Mentions: Cells of H. aurantiacus strain 114-95T are cylindrical measuring 1-1.5 μm by 5-10 μm (Figure 2) [1]. Cells are organized in sheathed filaments of 500 μm length or more [1]. However, the existence of a sheath in the classical sense has been questioned in an analysis of the fine structure of the cells [30]. Cells of strain 114-95T stain Gram-negative, are not flagellated but are motile via gliding and divide by the formation of a transverse septum [1]. Colonies are flat, spreading, and rough, and produce an orange pigment [1]. Pigment analyses of a related strain, H. giganteus Hp a2, showed that this strain produces γ-carotene, as well as glycosylated and acyl-glycosylated derivatives of 1′-hydroxy-4-keto-gamma-carotene [31]. Strain 115-95T is catalase-positive and hydrolyzes starch, gelatine, casein and tributyrin but not cellulose [1].
