The phylogenetic diversity of archaeal 16S rRNA genes in a thermoacidic spring field of
Ohwakudani, Hakone, Japan, was investigated by PCR-based analysis using a novel …

Scarce studies on microbial diversity in tropical caves have been published, a subterranean
system still neglected from a microbiological point of view. Although most published studies …

Arid environments are regular and well distributed over all continents and display drought
characteristics whether full-time or seasonal. This study aims to characterize how the …

The Cabo Rojo solar salterns are a hypersaline environment located in a tropical climate,
where conditions remain stable throughout the year. These conditions can favor the …

Methane gas (CH4) reservoirs have previously been reported in tropical marine sediments
of Saco do Mamanguá ria (Rio de Janeiro, Brazil). It is known that a methane microbiome …

The objective of the study was to elucidate the depth distribution and community
composition of Archaea in a temperate acidic forest soil. Numbers of Archaea and Bacteria …

Ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) are a diverse
and functionally important group in the nitrogen cycle. Nevertheless, AOA and AOB …

The nutrient and oxygen gradient present in marine sediments promotes high levels of
microbial diversity. We applied metagenomics and biogeochemical tools to analyze …

Microorganisms are in many ecosystems, and in the biosphere as a whole, by far the largest
component, in terms of both biomass and biological activity (Whitman et al., 1998). By their …

The microbial diversity of five unconnected high altitude (≥ 3800 m asl) wetlands from the
Chilean Altiplano was analyzed by a culture-independent approach, using 16 S rRNA gene …
