Phylogenetic diversity of subsurface marine microbial communities from the Atlantic and Pacific Oceans
Article Abstract:
The 16S rRNA phylogenetic diversity of subsurface marine microorganisms from the Pacific and Atlantic Oceans was reported. Samples from 100- and 500-m depths in the northeastern Pacific and from a 10-m depth in the Sargasso Sea near Bermuda were analyzed by a polymerase chain reaction method using universal primers, and 61 clones were sequenced. The marine populations contain both archaea and bacteria belonging to proteobacteria and cyanobacteria. A group related to gram-positive bacteria, one clone related to flavobacteria and clones from novel groups were also found. Moreover, the results suggest the lack of strongly dominant bacteria in the samples.

Recovery of crenarchaeotal ribosomal DNA sequences from freshwater-lake sediments
Article Abstract:
The ribosomal DNA sequences of crenarchaeotal archaea recovered from anaerobic freshwater-lake sediments in Michigan indicate that Crenarchaeota radiate into diverse ecologically important and temperate environments. The DNA sequences represent a monophyletic lineage, which is distinct from the genuine thermophilic crenarchaeota. There has been a transition from thermophilic to mesophilic and psychrophilic phenotypes within the kingdom, Crenarchaeota.

Microbial diversity of the brine-seawater interface of the Kebrit Deep, Red Sea, studied via 16S rRNA gene sequences and cultivation methods
Article Abstract:
Researchers have isolated a species of Halanaerobium from the anaerobic, deep-sea brine pool of the Kebrit Deep, Red Sea. These halophiles may play an important role in the degradation of organic material at the brine-seawater interface.
