Distribution and physiological characteristics of hyperthermophiles in the Kubiki oil reservoir in Niigata, Japan
Article Abstract:
Many hyperthermophiles can adapt to near starvation conditions, according to a study of Thermococcus and Thermotoga spp in the Kubiki oil reservoir in Japan. Fault blocks in the reservoir prevented the flow of nutrients, which did not affect Thermococcus concentrations but led to a decrease in Thermotoga cell density.

Amino acid requirements of two hyperthermophilic archaeal isolates from deep-sea vents, Desulfurococcus strain SY and Pyrococcus strain GB-D
Article Abstract:
The growth inability of hyperthermophiles in media containing simple carbohydrate, organic acids or alcohol is discussed. Desulforococcus and Pyrococcus strains were isolated fromdeep-sea hydrothermal vents and were utilized on free amino acids and peptides from various molecular weight fractions of yeast extract. The ability of the two isolates for growth in protein-containing mediums was found to be significantly different.

Dense community of hyperthermophilic sulfur-dependent heterotrophs in a geothermally heated shallow submarine biotope near Kodakara-Jima Island, Kagoshima, Japan
Article Abstract:
The sea-floor of an inlet of Kodakara-Jima island, Kagoshima, Japan was studied to determine the number of bacteria present in the sediments. Hot spots are present on the sea floor where as the depth of the sediment increased, the number of hyperthermophilic sulfur-dependent bacteria also increased, but the amino acid and the organic carbon content decreased. The hyperthermophilic bacteria probably use the amino acids for their growth and the areas surrounding the hot spots contained autotrophs which produced the organic matter.
