Query: NC_009495:3340000 Clostridium botulinum A str. ATCC 3502 chromosome, complete genome

Lineage: Clostridium botulinum; Clostridium; Clostridiaceae; Clostridiales; Firmicutes; Bacteria

General Information: This strain is a well-studied Hall strain that produces type A toxin. Produces botulinum, one of the most potent toxins known. This genus comprises about 150 metabolically diverse species of anaerobes that are ubiquitous in virtually all anoxic habitats where organic compounds are present, including soils, aquatic sediments and the intestinal tracts of animals and humans. This shape is attributed to the presence of endospores that develop under conditions unfavorable for vegetative growth and distend single cells terminally or sub-terminally. Spores germinate under conditions favorable for vegetative growth, such as anaerobiosis and presence of organic substrates. It is believed that present day Mollicutes (Eubacteria) have evolved regressively (i.e., by genome reduction) from gram-positive clostridia-like ancestors with a low GC content in DNA. Some species are capable of producing organic solvents (acetone, ethanol, etc,), molecular hydrogen and other useful compounds. This organism produces one of the most potent and deadly neurotoxins known, a botulinum toxin that prevents the release of acetylcholine at the neuromuscular junction, thereby inhibiting muscle contraction and causing paralysis. In most cases the diseased person dies of asphyxiation as a result of paralysis of chest muscles involved in breathing. The spores are heat-resistant and can survive in inadequately heated, prepared, or processed foods. Spores germinate under favorable conditions (anaerobiosis and substrate-rich environment) and bacteria start propagating very rapidly, producing the toxin. Botulinum toxin, and C. botulinum cells, has been found in a wide variety of foods, including canned ones. Almost any food that has a high pH (above 4.6) can support growth of the bacterium.

Subject: NC_009925:4997000 Acaryochloris marina MBIC11017, complete genome

Lineage: Acaryochloris marina; Acaryochloris; ; Chroococcales; Cyanobacteria; Bacteria

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.
