Species code:	HELMI
Taxonomy:	Bacteria; Firmicutes; Clostridia; Clostridiales; Heliobacteriaceae; Heliobacterium (TaxID: 498761) [NEWT/ NCBI]
Description:	Heliobacteria are the only photosynthetic Firmicutes. They are unique in using bacteriochlorophyll g as their major antennae pigment and an oxidized form of chlorophyll a, 8(1)-hydroxy-Chla as the primary electron acceptor for a type I reaction center (RC, related to photosytem I of oxygenic organisms). Unlike other anoxygenic bacteria they do not have any bacteriochlorophyll-containing internal membranes; pigments are found associated with RCs in the cell membrane. They also have unique carotenoids. Although photosynthetic they are obligatorily heterotrophic, as they have only a limited capacity for carbon metabolism, however they are capable of nitrogen fixation. Heliobacteria are capable of sporulation, although it occurs only rarely in pure cultures. Heliobacterium modesticaldum strain Ice1, the type strain of this species, was isolated from Icelandic hot spring volcanic soils. It grows optimally above 50 degrees Celsius, grows best photoheterotrophically, but can grow in the dark chemotrophically on pyruvate.
