Molecular characterization of microbial communities in deep coal seam groundwater of northern Japan
LIBSHUFF analysis revealed that N2 gas injected into the coal seam (for enhanced methane production) does not affect the coverage of archaeal and bacterial populations, but amova analysis does provide evidence for a change in the genetic diversity of Archaeal populations that are dominated by methanogens.
Phylogenetic Diversity of Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase Large-Subunit Genes from Deep-Sea Microorganisms
The phylogenetic diversity of the ribulose-1,5-bisphosphate carboxylase/oxygenase large-subunit genes of deep-sea microorganisms was analyzed and suggested that theThiobacillus-related RuBisCO may be distributed globally and contribute to the primary production in the deep sea.
Biomass of thraustochytrid protoctists in coastal water
It is suggested that the contribution of thraustochytrids to the microbial food chain and carbon cycling through organic degradation and production may not be negligible.

A total of 247 clones of 16S rRNA genes from microorganisms captured by 0.2- and 0.1-μm-pore-size filters from sedimentary and granite rock aquifers were amplified and yielded 37 operational taxonomic units (OTUs), representing novel lineages.
Communities of algae and cyanobacteria on glaciers in west Greenland
Abstract Communities of algae and cyanobacteria on two glaciers in west Greenland (the Qaanaaq and Russel glaciers) were analyzed and compared with the aim of explaining why the Qaanaaq Glacier (in…
Metagenomic Analysis of 0.2-μm-Passable Microorganisms in Deep-Sea Hydrothermal Fluid
The bulk DNA extracted from microorganisms that passed through 0.2-μm-pore-size filters and were trapped in the hydrothermal fluid of the Mariana Trough was pyrosequenced and found genes associated with a RND-type efflux transporter for exogenous substances were specifically identified in the present study.
Distribution and Phylogenetic Characteristics of the Genes Encoding Enzymes Relevant to Methane Oxidation in Oxygen Minimum Zones of the Eastern Pacific Ocean
Molecular Diversity of the Genes Encoding Ammonia Monooxygenase and Particulate Methane Monooxygenase from Deep-sea Sediments
Abundance of thraustochytrids in coastal plankton
It is suggested that thraustochytrids play an ecological role as alternative food sources for picoplankton feeders, as well as being actlve degraders and consumers in aquatic microbial food chains.
Microfabricated flow-through device for DNA amplification—towards in situ gene analysis
Abstract This study presents a microfabricated device for polymerase chain reaction (PCR) with a flow-through manner for use in environmental microbiology. The device was developed utilizing…
