		A facultative anaerobic organism is an organism, usually a bacterium, that makes ATP by aerobic respiration if oxygen is present but is also capable of switching to fermentation.
		In contrast, obligate anaerobes die in presence of oxygen.

	Anaerobic organism Summary
		A foul-smelling infection or drainage from an abscess is diagnostic of anaerobic infection.
		Anaerobes are bacteria that are either capable of growing in the absence of oxygen (referred to as facultative anaerobes) or that absolutely require the absence of oxygen (these are called obligate anaerobes).
		Anaerobic infections tend to involve the destruction of tissue, either because of bacterial digestion or because of destructive enzymes that are elaborated by the bacteria.

	Anaerobic organism (Site not responding. Last check: )
		Microaerophiles are organisms that may use oxygen, but only at low concentrations; their growth is inhibited by normal oxygen concentrations.
		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 toxin s (e.g., tetanus or botulinum toxins) that are highly dangerous to higher organisms, including humans.

	NAI News Article: Evolution’s Double Take
		Organisms that live in environments without oxygen, such as anaerobic fungi and protozoa (a type of protist), don’t use mitochondria at all —- instead their power is generated by hydrogenosomes, organelles that, while similar in many ways to mitochondria, follow a different metabolic pathway.
		The introduction of the aerobic bacteria allowed the anaerobic organism to survive in the oxygenated atmosphere, while the anaerobic organism provided nutrients for the aerobic bacteria.
		The NWO research team compared the hydrogenosomes of various protozoans and anaerobic fungi and discovered that the contents and form of these cell organelles differ from species to species.

		An anaerobic organism is any organism that does not require oxygen for growth and even dies in its presence.
		Aerotolerant organisms can survive in the presence of oxygen, but they are anaerobic because they do not use oxygen as a terminal electron acceptor.
		Obligate (strict) anaerobes die in presence of oxygen due to the absence of the enzymes superoxide dismutase and catalase which would convert the lethal superoxide formed in their cells due to the presence of oxygen.

	Differential Media - Oxygen Relationships
		Microaerophile: An organism that is capable of oxygen-dependent growth but cannot grow in the presence of a level of oxygen equivalent to that present in an air atmosphere (21% oxygen).
		The observed growth patterns of organisms in this medium determine their oxygen relationship designations (strict aerobe, facultative anaerobe, etc.) which correlate with such physiological abilities as respiration, fermentation and the catalase reaction and also whether there is an inhibitory effect on the organism in the presence of air.
		Thus, a description of a chemoheterotrophic organism as a "strict aerobe" can imply a number of associated characteristics that may be unnecessary to specify separately (able to respire, unable to ferment, catalase-positive, azide-sensitive, etc.).

	Bio200 Homework #4 KEY
		Instead, the pyruvate produced by glycolysis is converted to either lactate or ethanol (depending on the organism) by anaerobic fermentation.
		In many organisms pyruvate takes the place of oxygen and acts as the oxidizing agent of the electron carriers, yielding lactate (in lactic acid fermentation) or ethanol and carbon dioxide (in alcoholic fermentation).
		Anaerobic fermentation, as a result of only being able to perform glycolysis, produces much less energy than aerobic organisms that are able to carry out the citric acid cycle and electron transport chain by utilizing their supply of oxygen.
