Query: NC_014614:554949 Clostridium sticklandii, complete genome Lineage: Clostridium sticklandii; Clostridium; unclassified Peptostreptococcaceae; Clostridiales; Firmicutes; Bacteria General Information: This Clostridium (HF strain, ATCC 12662) was initially found associated with Methanococcus vannieli in formate-enriched cultures. After its isolation in pure culture, it was shown that this organism is capable of fermenting amino acids. Biochemical studies have shown that C. sticklandii obtains energy for growth from oxidation-reduction reactions between specific amino acid pairs. Clostridium sticklandii is a Gram-positive bacterium with low (G +C) content that is capable of fermenting amino acids.

General Information: Acaryochloris marina MBIC11017 was isolated from algae from the coast of the Palau Islands in the western Pacific. Marine cyanobacterium. Acaryochloris marina was first isolated as an epiphyte of algae. M. marina been isolated from a variety of habitats and locations, usually associated with algae but also as free-living organisms. This cyanobacterium produces an atypical photosynthetic pigment, chlorophyll d, as the major reactive agent. The oxygenic photosynthesis based on this pigment may have evolved as an acclimatization to far-red light environments, or an as intermediate between the red-absorbing oxygenic and the far-red-absorbing anoxygenic photosynthesis that uses bacteriochlorophylls. Because of the unusual ratio of chlorophyll a to chlorophyll d in this organism, it has been used as a model to study the spectrographic characteristics of the two pigments.
