Jena Microbial Resource Collection

from Wikipedia, the free encyclopedia

The Jena Microbial Resource Collection (JMRC, German: Jenaer Mikroorganismen-Sammlung) is a collection of microbial cultures for academic purposes. The JMRC belongs to both the Leibniz Institute for Natural Product Research and Infection Biology - Hans Knöll Institute Jena and the Institute for Microbiology at the Friedrich Schiller University Jena .

history

As early as the 1950s there was a mushroom culture collection at the University of Jena, based in Weimar. In 1999, this resulted in the Jena Pilz Reference Center. The JMRC was created in October 2010 from the merger of the collection of microorganisms and natural substances at the Hans Knöll Institute and the Mushroom Reference Center at the University of Jena.

Content, aim and purpose of the collection

With around 15,000 fungus isolates and around 35,000 bacteria isolates, the JMRC is the largest collection of its kind in Germany. The microorganisms are kept as active cultures or in cryopreservation.

The aim and purpose of this collection is the conservation of microbial resources for the screening of natural products and the investigation of the pathogenicity mechanisms of various mycoses in humans and animals.

The JMRC is a research facility that is only open to the general public on certain days, e.g. B. for the Long Night of the Sciences . The sending of isolates for research purposes can be requested by other academic institutions and companies. In the collection, emphasis is placed not only on conservation, but also on extensive occupation with current research areas in microbiology , especially mycology . In addition, topics related to the history of science are dealt with, e.g. B. the life's work of the mushroom researcher Johanna Schultze-Ways .

Examples of isolates

  • Lichtheimia corymbifera , a basal fungus that causes mucormycosis in humans
  • Conidiobolus coronatus , a basal fungus that causes entomophthoromycosis in humans
  • Parasitic mucorales such as B. Parasitella parasitica and their host organisms such. B. Absidia glauca (also belonging to the Mucorales)

Together with numerous domestic and foreign cooperation partners, a solid basis for collecting, preserving and research has been created.

The director of the JRMC is Kerstin Voigt .
