THERMOPHILIC BACTERIA FROM DEEP OCEAN BOTTOM CORES

Isolation and identification of obligate thermophilic sporeforming bacilli from ocean basin cores.

Bartholomew, J. W. (University of Southern California, Los Angeles), and George Paik. Isolation and identification of obligate thermophilic sporeforming bacilli from ocean basin cores. J. Bacteriol. 92:635-638. 1966.-Obligate thermophilic sporeforming aerobic bacilli were isolated from 11 ocean basin cores taken from locations in a 150 mile long area off of the coast from Ensenada, Mexico, to S...

Antibacterial 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...

Marine bacteria in deep Arctic and Antarctic ice cores

Thermophilic, anaerobic bacteria isolated from a deep borehole in granite in Sweden.

A borehole drilled to a total depth of 6779 m in granitic rock in Gravberg, Sweden, was sampled and examined for the presence of anaerobic, thermophilic, fermenting bacteria and sulfate-reducing bacteria. Growth in enrichment cultures was obtained only from water samples collected from a specific sampling depth in the borehole (3500 m). The hole was cased down to a depth of 5278 m and open to t...

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...
