SILVA - ribosomal RNA Databases

All Ribocon Services & Solutions related to microbial diagnostics (rRNA-gene-based identification, classification and phylogeny of microorganisms) are based on the SILVA rRNA data sets.

 

SILVA, located in Bremen, Germany, is a joined project of (1) the Opens external link in new window Max Planck Institute for Marine Microbiology and (2) Ribocon and represents one of the two main rDNA database projects in the world.

SILVA shows a number of outstanding features such as ...

  • more than 1 million rRNA-gene sequences for all three domains of life
  • own SILVA taxonomy: fully classified phylogenetic reference tree considering Bergey's Taxonomy
  • SSU (16/18S) and LSU (23/28S) data sets
  • probably the best rRNA-gene alignment as documented by peer-reviewed evaluation (Opens external link in new window Schloss PD, 2009)

 

Beside this, SILVA stands for detailed quality reporting and comprehensive documentation and support.

SILVA is absolutely free for users from the academic field and the full database content can be accessed, browsed and searched without any limitations via ...

SILVA and the Ribocon Services & Solutions in Diagnostics ...

rDNA-based identification and classification of microorganisms depends strongly on the quality of the underlying reference database. While the presence of low-quality, not correctly annotated and/or non-supplemented database entries (e.g. "uncultured bacterium") hampers any kind of analysis, the usage of high quality data sets even makes the results of a BLAST search as reliable as a phylogeny-mediated approach. This is demonstrated by our rapid rDNA identification technology as implemented for e.g. the freely available and fully documented Opens external link in new window Sepsitest-BLAST project.

As a member of the SILVA Database Project, we have the experience and the resources to easily set up customized data (sub)sets, adapted and optimized for specific tasks and solutions in Diagnostics. At the same time, the SILVA databases represent the backbone of the sequence analysis, phylogeny and probe-design services offered by Ribocon.
