ARB: a software environment for sequence data

The ARB (from Latin arbor, tree) project was initiated almost 10 years ago. The ARB program package comprises a variety of directly interacting software tools for sequence datab...

SILVA: a comprehensive online resource for quality checked and aligned ribosomal RNA sequence data compatible with ARB

Sequencing ribosomal RNA (rRNA) genes is currently the method of choice for phylogenetic reconstruction, nucleic acid based detection and quantification of microbial diversity. ...

Phylogenetic identification and in situ detection of individual microbial cells without cultivation

The frequent discrepancy between direct microscopic counts and numbers of culturable bacteria from environmental samples is just one of several indications that we currently kno...

Sequence Determination of rRNA Genes of Pathogenic Vibrio Species and Whole-Cell Identification of Vibrio vulnificus with rRNA-Targeted Oligonucleotide Probes

A comparative analysis of seven new 16S rRNA gene sequences of pathogenic Vibrio species with previously published vibrio sequences confirmed that Vibrio vulnificus represents a...

What are mycoplasmas: The relationship of tempo and mode in bacterial evolution

Dominating Role of an Unusual Magnetotactic Bacterium in the Microaerobic Zone of a Freshwater Sediment

A combination of polymerase chain reaction-assisted rRNA sequence retrieval and fluorescent oligonucleotide probing was used to identify in situ a hitherto unculturable, big, ma...
