Studies on thermophilic sulfate reducing bacteria. I. Identification of Sporovibrio desulfuricans as Clostridium nigrificans.
Elion (1924) was the first to isolate a thermophilic sulfate reducing bacterium in pure culture. He named the organism Vibrio thermodesulfuricans, and reported that it was capable of sulfate reduction betveen 30 and 65 C, wvith an optimum of 55 C. Baars (1930) and Kluyver and Baars (1932) reisolated V. thermodesulfuricans, and carried out a comparative study of this organism and Vibrio desulfur...
متن کاملTemperature-Dependent Alkyl Glycerol Ether Lipid Composition of Mesophilic and Thermophilic Sulfate-Reducing Bacteria
The occurrence of non-isoprenoid alkyl glycerol ether lipids in Bacteria and natural environments is increasingly being reported and the specificity and diagenetic stability of these lipids make them powerful biomarkers for biogeochemical and environmental studies. Yet the environmental controls on the biosynthesis of these peculiar membrane lipids remain poorly documented. Here, the lipid cont...
متن کاملNovel thermophilic sulfate-reducing bacteria from a geothermally active underground mine in Japan.
Thermophilic sulfate-reducing bacteria were enriched from samples obtained from a geothermal underground mine in Japan. The enrichment cultures contained bacteria affiliated with the genera Desulfotomaculum, Thermanaeromonas, Thermincola, Thermovenabulum, Moorella, "Natronoanaerobium," and Clostridium. Two novel thermophilic sulfate-reducing strains, RL50JIII and RL80JIV, affiliated with the ge...
متن کاملMetabolic Flexibility of Sulfate-Reducing Bacteria
Dissimilatory sulfate-reducing prokaryotes (SRB) are a very diverse group of anaerobic bacteria that are omnipresent in nature and play an imperative role in the global cycling of carbon and sulfur. In anoxic marine sediments sulfate reduction accounts for up to 50% of the entire organic mineralization in coastal and shelf ecosystems where sulfate diffuses several meters deep into the sediment....
متن کاملThermostable protease from thermophilic bacteria. II. Studies on the stability of the protease.
1. The effect of temperature on the conformation of the protease from Bacillus thermoproteolyticus was examined. 2. The thermostable enzyme is stable at room temperature against such denaturing reagents as urea, alcohol, and detergent. 3. However, these reagents accelerate the denaturation of the enzyme by heat. Materials-The crystalline protease of B. thermoproteolyticus was kindly supplied by...
