Extremely Thermophilic Marine Bacteria
A novel extremely thermophilic bacterium was isolated from a shallow marine hydrothermal vent environment (depth, 22 m) in Tachibana Bay, Nagasaki Prefecture, Japan. The cells of this organism were gramnegative rods. Growth occurred at temperatures between 50 and 85°C (optimum temperature, 80°C; doubling time at optimum temperature, 90 min), at pH 5.5 and 9.0 (optimum pH, 7.0), and in the prese...
متن کاملStudies 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 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...
متن کاملAntibacterial peptides from thermophilic bacteria
It is becoming interestingly apparent that innovations of the classical antibiotics are not effective, that induces need for novel drugs. Peptide antibiotics exhibit a group of secondary metabolites with hydrophobic and cyclic structures containing d-amino acidc like compounds with more resistant to proteolytic degradation. Bacterial peptides can possess bactericidal, fungicidal, metal chelatin...
متن کاملBiodesulfurization of Dibenzothiophene by a Newly Isolated Thermophilic Bacteria Strain
Microbiological analyses of soil chronically exposed to petroleum complex compounds of some oil springs in south of Iran resulted in isolation and purification of a new native thermophilic strain which is capable to desulfurize petroleum sulfur compounds by 4-S mechanism. Dibenzothiophene (DBT) was selected as a complex sulfur compound model and many experiments were done to identify the me...
