New bioinformatics platform for the genome-based taxonomical classification of bacteria and archaea

21.05.2019

Dr. Jan P. Meier-Kolthoff and Associate Professor Dr. Markus Göker develop Type Strain Genome Server (TYGS)

“TYGS is an automated high-throughput platform for state-of-the-art genome-based taxonomy”, is the title of the paper published in the current issue of the internationally renowned journal Nature Communications.

In this paper, Dr. Jan P. Meier-Kolthoff and Ass. Prof. Dr. Markus Göker, both of the Department for Bioinformatics at the Leibniz Institute DSMZ-German Collection of Microorganisms and Cell Cultures, share their findings regarding the new Type Strain Genome Server TYGS.

Scientists at the DSMZ developed this Type (Strain) Genome Server (TYGS: https://tygs.dsmz.de) as a bioinformatics platform for the genome-based taxonomy of bacteria and archaea. The server is based on a database with weekly updates, which links comprehensive information on taxonomy and nomenclature to almost 9,000 microbial type strain genome sequences and essentially all type strain 16S sequences.

The Type (Strain) Genome Server uses a high-throughput process to automatically determine the type strain genome sequences most closely related to one (or up to several) user-defined genome sequences, and from there calculates, amongst others, a true genome-based family tree, a categorization of species and subspecies using digital DNA:DNA hybridization, and all differences in genomic GC-Content.

For this, the TYGS uses a number of scientifically established and frequently cited methods including the Genome-to-Genome Distance Calculator (GGDC) or a phylogenomic process called Genome BLAST Distance Phylogeny (GBDP).

The user receives a specific link to an interactive website of the TYGS-server containing all relevant information in form of tables, modifiable figures ready for publication, references on taxonomy literature as well as complete texts on methods and results.

The data can be integrated directly into microbiological studies and papers; in addition, the user is also able to exchange them with cooperation partners via the web link provided.

Should the phylogenetic environment be thought to not yet contain genome-sequenced type strains, the user may conveniently use TYGS on the basis of this result to request a more comprehensive tree analysis of the 16S rRNA gene sequences.

About the Leibniz Institute DSMZ
The Leibniz Institute DSMZ-German Collection of Microorganisms and Cell Cultures is the world's most diverse collection of biological resources (bacteria, archaea, protists, yeasts, fun-gi, bacteriophages, plant viruses, genomic bacterial DNA as well as human and animal cell lines). Microorganisms and cell cultures are collected, investigated and archived at the DSMZ. As an institution of the Leibniz Association, the DSMZ with its extensive scientific services and biological resources has been a global partner for research, science and industry since 1969. The DSMZ is the first registered collection in Europe (Regulation (EU) No. 511/2014) and certified according to the quality standard ISO 9001:2015. As a patent depository, it offers the only possibility in Germany to deposit biological material in accordance with the requirements of the Budapest Treaty. In addition to scientific services, research is the second pillar of the DSMZ. The institute, located on the Science Campus Braunschweig-Süd, accommodates more than 69,701 cultures and biomaterials and has 198 employees. www.dsmz.de

The Leibniz Association
The Leibniz Association connects 95 independent research institutions that range in focus from the natural, engineering and environmental sciences via economics, spatial and social sciences to the humanities. Leibniz Institutes address issues of social, economic and ecological relevance. They conduct knowledge-driven and applied basic research, maintain scientific infrastructure and provide research-based services. The Leibniz Association identifies focus areas for knowledge transfer to policy-makers, academia, business and the public. Leibniz institutions collaborate intensively with universities – in the form of “Leibniz ScienceCampi” (thematic partnerships between university and non-university research institutes), for example – as well as with industry and other partners at home and abroad. They are subject to an independent evaluation procedure that is unparalleled in its transparency. Due to the importance of the institutions for the country as a whole, they are funded jointly by the Federation and the Länder, employing some 19,100 individuals, including 9,900 researchers. The entire budget of all the institutes is approximately 1.9 billion Euros. www.leibniz-gemeinschaft.de

Im Focus: A step towards controlling spin-dependent petahertz electronics by material defects

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.

Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...

Im Focus: Freiburg researcher investigate the origins of surface texture

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.

Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Im Focus: Making the internet more energy efficient through systemic optimization

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.

Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.

Im Focus: New synthesis methods enhance 3D chemical space for drug discovery

After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.

"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
