Molecular phylogenetic analysis of archaeal intron-containing genes coding for rRNA obtained from a deep-subsurface geothermal water pool

Article Abstract:

Molecular phylogenetic analysis has been carried out for archaeal intron-containing genes coding for rRNA. The DNA was obtained from a deep-subsurface geothermal water pool in a production well of a geothermal plant. Phylogenetic diversity was found to be very low. Only hyperthermophilic archaeal members closely related to Pyrobaculum were found.

Culture-dependent and -independent characterization of microbial communities associated with a shallow submarine hydrothermal system occurring within a coral reef off Taketomi Island, Japan

Article Abstract:

Insightful studies of sustained survival of the microbial communities in a shallow submarine hydrothermal system near Taketomi Island, Japan are presented. The survival among microbial communities is more influenced by active chemosynthetic primary production than photosynthetic production in abundant sunlight.

Rapid detection and quantification of members of the archaeal community by quantitative PCR using fluorogenic probes

Article Abstract:

A fluorogenic PCR method using the TaqMan probe was used to detect and quantify archaeal rDNA in natural microbial communities. This technique can be used to document the widespread occurrence of these bacteria both in extreme and non-extreme environments.
