Molecular characterization of community structures and sulfur metabolism within microbial streamers in Japanese hot springs

Article Abstract:

Community structures of submerged microbial slime streamers (SMSS) in sulfide- containing hot springs at 72 to 80 degree Celsius at Nakabusa and Yumata, Japan were investigated by molecular analysis based on the 16S rRNA gene. The analyses provided a more comprehensive understanding of the microbial sulfur metabolism of as-yet-uncultivated Thermodesulfobacteria and sulfurihydrogenibium- like microbes in the SMSS.

Analysis of diversity and activity of sulfate-reducing bacterial communities in sulfidogenic bioreactors using 16S rRNA and dsrB genes as molecular markers

Article Abstract:

The diversity and activity of sulfate-reducing bacteria (SRB) in sulfidoenic bioreactors are described by using simultaneous analysis of PCR products obtained from DNA and RNA of the 16S rRNA and dissimilatory sulfite reductase (dsrAB) genes. The metabolically active SRB is identified in sulfidogenic bioreactors by using the functional gene dsrAB as a molecular marker.

Suspension array analysis of 16S rRNA from Fe- and [SO4.sup.2]-reducing bacteria in uranium-contaminated sediments undergoing-bioremediation

Article Abstract:

A developed 16S rRNA-targeted tunable bead array was used in a retrospective analysis of metal- and sulfate-reducing bacteria in contaminated subsurface sediments undergoing in situ U(VI) bioremediation. The study indicated that the behavior and response of the 16S rRNA-targeted oligonucleotide probes could not be predicted based on the primary nucleic acid sequence.
