		Microbes of the deinococci family appear to be widely distributed in soils and have been routinely isolated from organically rich as well as dry, nutrient-poor environments.
		Therefore, it is possible that deinococci capable of reducing metal and radionuclides may be native to some contaminated environments.
		Additional research is required to better understand the ecology of the deinococci and the potential for naturally occurring strains to reduce metals.

		The capacity to survive such massive insults to their genetic integrity suggests that the Deinococcaceae have evolved distinctive mechanisms of DNA damage tolerance and available evidence argues that efficient DNA repair is an integral part of this tolerance.
		The enzymology of the deinococci's DNA repair processes is poorly understood, however.
		It is the long term objective of this project to develop a comprehensive explanation for the deinococci's remarkable resistance to ionizing radiation.

	1999 Progress Report - GENETIC ENGINEERING OF A RADIATION RESISTANT BACTERIUM FOR BIODEGRADATION OF MIXED WASTE (Site not responding. Last check: 2007-11-01)
		The deinococci have a very quick and accurate DNA repair system, are able to withstand ionizing radiation doses in the 5 Mrad range, and show no loss of viability at 500 krad.
		However, deinococci do not appear to have a natural ability to degrade toxic organics.
		In this study, our approach is to select enzymes that have the potential to allow D. radiodurans to attack organics of concern, to clone the genes encoding these enzymes into the chromosome of the bacterium, and to evaluate the level of expression, the stability, and the effect of the genes on D. radiodurans.

		The mechanism for the radiation repair properties of this organism is unknown, however, genetic inactivation of the so far uncharacterized IrrI gene of the bacterium renders this organism extremely sensitive to ionizing radiation.
		This implies that the IrrI protein plays a pivotal role in the ionizing radiation resistance of the deinococci.
		Evidence has been obtained that indicates that IrrI is an inhibitor of a exonucleolytic activity that causes an immediate breakdown of chromosomal DNA following the cell's exposure to UV and gamma radiation.

		There are only three known genera in this group: Deinococcus, Deinobacter and Thermus.
		Deinococcus and Deinobacter are very closely related, and are together known as the 'Deinococci'.
		Therefore the unknown is a member of the Deinococci.
