	Anaerobic organism - Wikipedia, the free encyclopedia
		An anaerobic organism or anaerobe is any organism that does not require oxygen for growth.
		Anaerobic bacteria and archaea use these and many other fermentative pathways, e.g., propionic acid fermentation, butyric acid fermentation, solvent fermentation, mixed acid fermentation, butanediol fermentation, Stickland fermentation, acetogenesis or methanogenesis.
		Some anaerobic bacteria produce toxins (e.g., tetanus or botulinum toxins) that are highly dangerous to higher organisms, including humans.

	Gale Encyclopedia of Medicine: Anaerobic infections
		Anaerobic bacteria can cause an infection when a normal barrier (such as skin, gums, or intestinal wall) is damaged due to surgery, injury, or disease.
		Anaerobic bacteria are common causes of diabetic skin ulcers, gangrene, destructive infection of the deep skin and tissues (necrotizing fascitis), and bite wound infections.
		This foul smell is produced by anaerobic bacteria and occurs in one third to one half of patients late in the infection.

	Chapter 1
		Anaerobic decomposition takes place in nature, as in the decomposition of the organic muds at the bottom of marshes and in buried organic materials to which oxygen does not have access.
		Bacteria likely to be found in a compost heap are aerobic bacteria that specialize in breaking down organic compounds and thrive in temperatures ranging up to 170°F (77°C).
		The reason bacteria tend to die rapidly as actinomycete populations grow in the compost pile is that actinomycetes have the ability to produce antibiotics, chemical substances that inhibit bacterial growth.

		The anaerobic bacteria to be enriched for in this project was isolated from a sample of mud from the edge of a pond located in Winter Park, FL.
		Each grid square on the anaerobic agar was then inoculated with a different organism from each of the streak plates (pinoculated and incubated previously) using a sterile toothpick and each equivalent square on the nutrient agar plate was inoculated with the same organism as that of the anaerobic agar plate.
		A streak-plate inoculation of the anaerobic bacteria was prepared to obtain a pure culture as seen in figure 5.

	Bacteria
		Bacteria are the smallest living organisms and the most numerous in compost; they make up 80 to 90% of the billions of microorganisms typically found in a gram of compost.
		Bacteria are responsible for most of the decomposition and heat generation in compost.
		But those anaerobic metabolites do not escape the worm bin, since as the alcohols, phenols, terpenes, and volatile organic acids volatilize upwards, they pass through the aerobic areas of the worm bin and are consumed by aerobic organisms.

	Infection With Anaerobic Bacteria (Site not responding. Last check: 2007-10-08)
		It is often the case that anaerobic bacteria and facultative anaerobes are both present in infected tissue.
		These anaerobic bacteria are good things to have in a colon but bad things to have in a wound (infection),a brain or a lung (abscess).
		Infection with anaerobes like these is generally endogenous (infection with persons own normal flora), often consists of multiple species of anaerobic bacteria mixed together often with some facultative anaerobes also.

		Anaerobic Gram-negative bacilli are common elements of the mucous membrane flora throughout the body; they often act as secondary pathogens.
		Gram-negative anaerobic bacilli may cause infections anywhere in the body; the most common types are oral and dental, pleuropulmonary, intra-abdominal, female genital tract and skin, soft tissue and bone infections (Table 20-1).
		Anaerobic bacteremia following dental manipulation may be managed effectively by administering an antibacterial agent 1 hour before the manipulation and continuing for a limited period (12 to 24 hours) afterward.

	Susceptibility Testing, Anaerobic Bacteria
		Anaerobic infections are frequently mixed involving aerobic and anaerobic flora, thus, the predictive value of an anaerobic susceptibility test for a successful clinical outcome may be limited by the complexity of the clinical infection.
		Anaerobe isolate from patient is not available or fails to give adequate growth for susceptibility testing.
		Infections involving anaerobes frequently contain mixed flora and appropriate drainage rather than antimicrobial therapy seems to be the most crucial factor in the successful treatment of these infections.

		By separating the bacteria from the effluent stream and keeping them in the reactor, he was able to reduce the retention time for efficient treatment down to as low as 2 days in the laboratory scale treatment of several different wastewaters from the fermentation industry.
		The sediments of hypersaline water bodies are generally anaerobic, partly as a result of biological activity in the sediments and the overlaying water, and also because of the limited solubility of oxygen in hypersaline brine.
		The biology of anaerobic hypersaline environments has been relatively little studied, though it is curious to note that the first bacteria ever isolated from the hypersaline environment (though not halophilic ones), Clostridia, causing tetanus and gas gangrene, was isolated by Lortet from Dead Sea mat in the end of the 19th Century (Oren 1983).

		In these bacteria, propionate is formed by the partial reversal of the Krebs cycle reactions and involves a CO fixation by pyruvate (the Wood-Werkman reaction) that forms oxaloacetate (a four-carbon intermediate).
		Bacteria that grow solely at the expense of inorganic compounds (mineral ions), without using sunlight as an energy source, are called autotrophs, chemotrophs, chemoautotrophs, or chemolithotrophs.
		Note that all autotrophic and phototrophic bacteria possess essentially the same organic cellular constituents found in heterotrophic bacteria; from a nutritional viewpoint, however, the autotrophic mode of metabolism is unique, occurring only in bacteria.

	Anaerobic Bacteria
		Obligate anaerobes cannot survive in an oxygen environment because they lack sufficient levels of the enzymes that allow them to detoxify the super oxide ion (i.e., peroxidases, catalase, and most importantly, superoxide dismutase).
		Anaerobic infection causes the formation of purulent abscesses. There is tissue breakdown, invasion by PMNs, and finally, the abscess is walled off. However, in the damaged and poorly oxygenated abscess tissue, the phagocytes are not able to eliminate the anaerobes. For this reason, abscesses usually have to be drained.
		Anaerobes are exquisitely sensitive to this drug because it must be reduced to become a toxic compound that inhibits DNA synthesis.

		Anaerobes (literally meaning "without air") are organisms that do not use oxygen to live.
		If the anaerobe dies in the presence of oxygen, it is a strict (obligate) anaerobe.
