The members of this group grow chemolithoautotrophically using zero valent sulfur, molecular hydrogen or reduced sulfur compounds as electron donors and nitrate, nitrite and oxygen as electron acceptors.Metal sulfur dioxide complex: Metal sulfur dioxide complexes are complexes that contain sulfur dioxide, SO2, bonded to a transition metal. Such compounds are common but are mainly of theoretical interest.Perchloromethyl mercaptanKonzoOrganosulfur compounds: Organosulfur compounds are organic compounds that contain sulfur. They are often associated with foul odors, but many of the sweetest compounds known are organosulfur derivatives, e.Methanesulfonic acidSteven NovellaNational Offshore Petroleum Safety Authority: The National Offshore Petroleum Safety Authority (NOPSA) was the occupational health and safety (OHS) regulator for the Australian offshore petroleum industry between 2005 and 2011. The role of regulator has been transferred to NOPSEMA - the National Offshore Petroleum Safety and Environmental Management Authority from the first of January 2012.Table of standard reduction potentials for half-reactions important in biochemistry: The values below are standard reduction potentials for half-reactions measured at 25°C, 1 atmosphere and a pH of 7 in aqueous solution.SRX expansion boardVidalia onion: A Vidalia onion ( or ) is a sweet onion of certain varieties, grown in a production area defined by Georgia law and by the United States Code of Federal Regulations (CFR). The varieties include the hybrid yellow granex, varieties of granex parentage, and other similar varieties recommended by the Vidalia Onion Committee and approved by the U.MethionineAromadendrinPurple sulfur bacteria: The purple sulfur bacteria are a group of Proteobacteria capable of photosynthesis, collectively referred to as purple bacteria. They are anaerobic or microaerophilic, and are often found in hot springs or stagnant water.Eyes (cheese): Eyes are the round holes that are a characteristic feature of Swiss-type cheeseP.L.Deep chlorophyll maximum: A deep chlorophyll maximum (DCM) is a subsurface maximum in the concentration of chlorophyll in the ocean or a lake. A DCM is not always present--sometimes there is more chlorophyll at the surface than at any greater depth--but it is a common feature of most aquatic ecosystems.Ammonium sulfamateLewisiteBrevibacterium iodinum: Brevibacterium iodinum is a Gram-positive soil bacterium. It can often be found among the normal cutaneous flora of healthy people, particularly in humid environments, and is only very rarely involved in opportunistic infections.Gas chromatography–mass spectrometry: right|300 px|Example of a GC-MS instrument|thumbBenzo(c)thiopheneColes PhillipsRhodococcus fascians: Rhodococcus fascians (known as Corynebacterium fascians until 1984) is a Gram positive bacterial phytopathogen that causes leafy gall disease. R.FerroceneBiodegradationExogenous bacteria: Exogenous bacteria are microorganisms introduced to closed biological systems from the external world. They exist in aquatic and terrestrial environments, as well as the atmosphere.PhytomedicineStratosphere: The stratosphere is the second major layer of Earth's atmosphere, just above the troposphere, and below the mesosphere. It is stratified in temperature, with warmer layers higher up and cooler layers farther down.Eagle's minimal essential medium: Eagle's minimal essential medium (EMEM) is a cell culture medium developed by Harry Eagle that can be used to maintain cells in tissue culture.McIntosh and Filde's anaerobic jar: McIntosh and Filde's anaerobic jar is an instrument used in the production of an anaerobic environment. This method of anaerobiosis as others is used to culture bacteria which die or fail to grow in presence of oxygen (anaerobes).Glucose-methanol-choline oxidoreductase family: In molecular biology, the glucose-methanol-choline oxidoreductase family (GMC oxidoreductase) is a family of enzymes with oxidoreductase activity.Carbonyl sulfideDNA sequencer: A DNA sequencer is a scientific instrument used to automate the DNA sequencing process. Given a sample of DNA, a DNA sequencer is used to determine the order of the four bases: G (guanine), C (cytosine), A (adenine) and T (thymine).DsbC protein family: DsbC (Disulfide bond C) is a prokaryotic disulfide bond isomerase. The formation of native disulfide bonds play an important role in the proper folding of proteins and stabilize tertiary structures of the protein.Branching order of bacterial phyla (Gupta, 2001): There are several models of the Branching order of bacterial phyla, one of these was proposed in 2001 by Gupta based on conserved indels or protein, termed "protein signatures", an alternative approach to molecular phylogeny. Some problematic exceptions and conflicts are present to these conserved indels, however, they are in agreement with several groupings of classes and phyla.Fecal coliform: A fecal coliform (British: faecal coliform) is a facultatively anaerobic, rod-shaped, gram-negative, non-sporulating bacterium. Coliform bacteria generally originate in the intestines of warm-blooded animals.Pelagibacter ubique: Pelagibacter, with the single species P. ubique, was isolated in 2002 and given a specific name, although it has not yet been validly published according to the bacteriological code.Nankai Trough gas hydrate site: Nankai Methane Hydrate Site (or Japanese Methane Hydrate R&D Program at Nankai, Nankai Trough Methane Hydrate Site) is located in the Nankai Trough, Japan.Amplified Ribosomal DNA Restriction Analysis: Amplified rDNA (Ribosomal DNA) Restriction Analysis is the extension of the technique of RFLP (restriction fragment length polymorphism) to the gene encoding the small (16s) ribosomal subunit of bacteria. The technique involves an enzymatic amplification using primers directed at the conserved regions at the ends of the 16s gene, followed by digestion using tetracutter Restriction enzymes.College of Practitioners of PhytotherapyFerric uptake regulator family: In molecular biology, the ferric uptake regulator (FUR) family of proteins includes metal ion uptake regulator proteins. These are responsible for controlling the intracellular concentration of iron in many bacteria.Heliobacteria: The heliobacteria are phototrophic: they convert light energy into chemical energy by photosynthesis and they use a Type I reaction centerHeinickel and Golbeck 2007. The primary pigment involved is bacteriochlorophyll g, which is unique to the group and has a unique absorption spectrum; this gives the heliobacteria their own environmental niche.
