Thermophiles : The Keys to the Molecular Evolution and the Origin of Life?

Autor: Juergen Wiegel, Adams W.W. Michael

Late-1990s developments in the study of thermophiles have had considerable significance on theories of evolution. These micro-organisms are able to thrive at temperatures near or even above 100 degrees Celsius, and scientists have begun to study thei

Thermoanaerobacter ethanolicus gen. nov., spec. nov., a new, extreme thermophilic, anaerobic bacterium

Autor: Lars G. Ljungdahl, Jürgen Wiegel

Publikováno v: Archives of Microbiology. 128:343-348

Two strains, JW 200 and JW 201, of an extreme thermophilic, non-spore-forming anaerobic bacterium were isolated from alkaline and slightly acidic hot springs located in Yellowstone National Park. Both strains were peritrichously flagellated rods. Cel

Leucine biosynthesis in Alcaligenes eutrophus H16: Influence of amino acid additions on the formation of active ?-isopropylmalate synthase and ?-acetohydroxy acid synthase

Autor: Jürgen Wiegel

Publikováno v: Archives of Microbiology. 142:194-199

The α-isopropylmalate synthase of the chemolithoautotrophic Alcaligenes eutrophus H16 is apparently a soluble enzyme but is strongly adsorbed to cell particles in ruptured cell suspensions. This was not observed with α-acetohydroxy acid synthase or

A yellow affinity substance involved in the cellulolytic system ofClostridium thermocellum

Autor: Jürgen Wiegel, Bert Pettersson, Karl-Erik Eriksson, Lars G. Ljungdahl

Publikováno v: Current Microbiology. 9:195-199

Clostridium thermocellum produces a yellow substance when fermenting cellulose. This substance is attached to the cellulose particles. Cellulose with the yellow substance, obtained from cultures ofC. thermocellum, binds effectively endo-1,4-β-glucan

Autor: Gerhard Gottschalk, Jürgen Wiegel, Manfred Braun

Publikováno v: Current Microbiology. 5:255-260

Fourteen strains of a thermophilic, rod-shaped, peritrichously flagellatedClostridium species were isolated from various mud and soil samples. Round to slightly oval spores were formed in terminal position. The isolates were obligate anaerobes and gr
