Phylogenetic Oligodeoxynucleotide Probes for the Major Subclasses of Proteobacteria: Problems and Solutions
Based on comparative analyses of 16S and 23S ribosomal RNA sequences, sites specific for the alpha-, beta-, and gamma-subclasses of Proteobacteria are located and will be useful for determinative studies and for the in situ monitoring of population distribution and dynamics in microbial communities.

Sponge-Associated Microorganisms: Evolution, Ecology, and Biotechnological Potential
The ecology of sponge-microbe associations is examined, including the establishment and maintenance of these sometimes intimate partnerships, the varied nature of the interactions (ranging from mutualism to host-pathogen relationships), and the broad-scale patterns of symbiont distribution. Expand
The domain-specific probe EUB338 is insufficient for the detection of all Bacteria: development and evaluation of a more comprehensive probe set.
Two supplementary versions of probe EUB338 are designed and evaluated for in situ detection of most of those phyla not detected with this probe, which should allow a more accurate quantification of members of the domain Bacteria in future molecular ecological studies. Expand
Phylogeny of dissimilatory sulfite reductases supports an early origin of sulfate respiration.
It is concluded that the high similarity of bacterial and archaeal DSRs reflects their common origin from a conserved DSR, which was either present before the split between the domains Bacteria, Archaea, and Eucarya or laterally transferred between Bacteria and Archaea soon after domain divergence.

Complete nitrification by Nitrospira bacteria
The discovery and cultivation of a completely nitrifying bacterium from the genus Nitrospira, a globally distributed group of nitrite oxidizers, and the genome of this chemolithoautotrophic organism encodes the pathways both for ammonia and nitrite oxidation. Expand
Molecular Evidence for a Uniform Microbial Community in Sponges from Different Oceans
A picture emerges where sponges can be viewed as highly concentrated reservoirs of so far uncultured and elusive marine microorganisms. Expand
A moderately thermophilic ammonia-oxidizing crenarchaeote from a hot spring
The enriched AOA, which is provisionally classified as “Candidatus Nitrososphaera gargensis,” is the first described thermophilic ammonia oxidizer and the first member of the crenarchaeotal group I.1b for which ammonium oxidation has been verified on a cellular level. Expand
Phylogenetic probes for analyzing abundance and spatial organization of nitrifying bacteria.
Volume 62, no. 6, p. 2157, Table 1: the sequence for probe Nso1225, 5(prm1)-CGCGATTGTATTACGTGTGA-3(prm1), should read 5(prm1)-CGCCATTGTATTACGTGTGA-3(prm1). [This corrects the article on p. 2156 inExpand
Nitrososphaera viennensis, an ammonia oxidizing archaeon from soil
The cultivation and isolation of an AOA from soil is described, showing it grows on ammonia or urea as an energy source and is capable of using higher ammonia concentrations than the marine isolate, Nitrosopumilus maritimus. Expand
Molecular evidence for genus level diversity of bacteria capable of catalyzing anaerobic ammonium oxidation.
The microbial community structure of a trickling filter biofilm with a high anaerobic ammonium oxidation activity is investigated and it is revealed that ammonia-oxidizing bacteria of the beta-subclass of Proteobacteria were also present, albeit in significant smaller amounts, within the anoxic biofilm.
