		Stetter's latest hot-vent discovery came from the Kolbiensey Ridge, just north of Iceland- the ironic land of ice and volcanoes - which he calls "one of my major hunting grounds." Stetter collected samples of hot rocks about 120 meters deep, using the Jago research submarine.
		Stetter and colleagues from the University of Regensburg and the Max Planck Institute, in Heidelberg, published the findings in May 2002 in the journal Nature.
		The genome, Stetter says, turns out to be slightly smaller than 0.5 megabases, about a tenth of the size of the E.

		Recently, Dr. Stetter has worked extensively with Diversa on the organism Nanoarchaeum equitans, one of his important discoveries, which was described in the Journal Nature in May of 2002.
		The majority of Dr. Stetter's research has focused on sampling, isolating and characterizing archaeal organisms which comprise the third domain of life.
		The collective work by Dr. Stetter and Diversa to characterize Nanoarchaeum equitans supports theories that Archaea is among the oldest forms of life on earth and has existed for billions of years.

		This observation could explain that the titer as determined by serial dilution is always at least 10 times higher than that determined by direct counting in the light microscope.
		The smallest cell sizes observed are in the 200 to 300 nanometer range and the ability of hyperthermophilic archaea to form those may be of great advantage to pass narrow pores of soils and rocks in order to colonize hot subterranean environments.

	Karl Stetter - Wikipedia, the free encyclopedia
		Karl Otto Stetter (born July 16, 1941) is a German microbiologist and authority on astrobiology.
		Nanoarchaeum equitans, an archaeal microorganism containing the world's smallest known genome, was discovered by Stetter in 2002 in a hydrothermal vent off the coast of Iceland.
		Among the other extremophiles discovered by Dr Stetter has been Pyrococcus furiosus, which was found on the Italian island of Vulcano in 1986.

		The creatures are small spheres attached to other organisms and are so genetically strange and so tiny--smaller than a grain of sand and about the width of four human hairs--that they were invisible to traditional ecological survey methods.
		Stetter and his colleagues detected the creatures only after growing them in hot, oxygen-free and high-pressure conditions to simulate their natural hostile environs.
		Sharp eyes and a nifty lab tool called optical tweezers--which let scientists manipulate tiny and fragile objects with a laser beam focused through a microscope--allowed Stetter's team to separate the organisms from their hosts.

		Last May, Diversa (nasdaq: DVSA - news - people), a San Diego-based biotech for which Stetter is a scientific adviser, announced that it had mapped the genome of N.

		Archaea are divided into two main groups based on rRNA trees, the Euryarchaeota and Crenarchaeota.
		Two other groups have been tentatively created for certain environmental samples and the peculiar species Nanoarchaeum equitans, discovered in 2002 by Karl Stetter, but their affinities are uncertain.
		Woese argued that the bacteria, archaea, and eukaryotes each represent a primary line of descent that diverged early on from an ancestral progenote with poorly-developed genetic machinery.
