'Karl Otto Stetter' (born
July 16,
1941) is a German
microbiologist and authority on
astrobiology. He is an expert on microbial life at high temperatures, and one of the most important
scientists currently working in this field.
Career
Stetter was born in
Munich and studied
biology at the Technische Universität Munich. He wrote his doctoral dissertation on
lactobacilli. From 1980 to 2002 he was professor at, and head of, the department of microbiology and of the
Archaea center of the Universität
Regensburg.
The majority of Professor Stetter's research has focused on sampling, isolating and characterizing archaeal organisms which comprise the third
domain of life, particularly undiscovered extremely heat-loving (''hyperthermophilic'')
bacteria and
Archaea, also called
extremophiles, growing optimally between 80 and 113°C.
Major discovery
''
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. This
archaebacterium which was described in the scientific journal ''Nature'' in May 2002.
Discoveries
Among the other extremophiles discovered by Dr Stetter has been ''
Pyrococcus furiosus'', which was found on the Italian island of
Vulcano in 1981. This extremophile was the source of
Pfu DNA polymerase. Stetter also discovered ''
Aquifex aeolicus'' and ''
Aquifex pyrophilus''.
Awards and Memberships
In 2003 Stetter was honored with the
Leeuwenhoek Medal by the
Royal Netherlands Academy of Arts and Sciences, an award given every 10 years to the scientist who has made the most outstanding contributions to the advancement of microbiology.
