The tetrameric manganese superoxide dismutase from the extreme thermophile Thermus thermophilus HB8 crystallizes in space group P41212 (or its enantiomorph) with a = b = 147.5 A, c = 55.9 A. The diffraction patterns extent to 1.4 A, and the crystals are very resistant to decay induced by x-irradiation. Measurements of the crystal density in Ficoll gradients are consistent with an asymmetric uni...
We describe a method to genetically manipulate Chaetomium thermophilum, a eukaryotic thermophile, along with various biochemical applications. The transformation method depends on a thermostable endogenous selection marker operating at high temperatures combined with chromosomal integration of target genes. Our technique allows exploiting eukaryotic thermophiles as source for purifying thermost...
BACKGROUND Clostridium clariflavum is an anaerobic, thermophilic, Gram-positive bacterium, capable of growth on crystalline cellulose as a single carbon source. The genome of C. clariflavum has been sequenced to completion, and numerous cellulosomal genes were identified, including putative scaffoldin and enzyme subunits. RESULTS Bioinformatic analysis of the C. clariflavum genome revealed 49...
Coliforms, enterococci, thermodurics, thermophiles, and psychrophiles in untreated farm pond waters.
Untreated waters from ten farm ponds located in central, north central, southeastern, and southwestern Ohio were examined for numbers of coliforms, enterococci, thermodurics, thermophiles, and psychrophiles. The median population densities per 100 ml water for all ponds were: coliforms, 23; enterococci, 3.6; thermodurics, 6,000; thermophiles, 450; psychrophiles, 1,000. The results indicate that...
