Microbial Strain Collection of Latvia

The Microbial Strain Collection of Latvia (MSCL), is a structural unit of University of Latvia, Faculty of Medicine and Life Sciences, Institute of Microbiology and Biotechnology. MSCL is the largest microbiological resource repository in Latvia, its activities are focused on preserving biological diversity ex situ and developing microbiology and biotechnology fields that are traditionally characteristic and promising for Latvia. The collection holds more than 1,700 different cultures of bacteria, yeasts and filamentous fungi, from which the majority were isolated in Latvia and are the only samples of their kind. Microorganisms are stored in a metabolically inactive state—in liquid nitrogen.

Microorganisms from the collection are used for research and educational purposes at the University of Latvia and other academic institutions, as well as for commercial orders. MSCL is also involved in the educational process at the University of Latvia, with several students annually working on their bachelor's and master's theses based on the MSCL collection.

The Collection is a member of the World Federation for Culture Collections (WFCC) European Culture Collection's Organization (ECCO), World Data Centre for Microorganisms (WDCM), and European Research Infrastructure Consortium for Microbial Resource Research (MIRRI-ERIC).

MSCL is also the coordinator of the national node of Latvia for MIRRI-ERIC. MSCL, as an international depositary authority under the Budapest Treaty, accepts bacteria, fungi (including yeasts), and plasmids in host cells, except for pathogenic microorganisms belonging to biological agent groups 3 and 4 for patenting.

Issuance of microorganism cultures:
EUR 28.46 + VAT per culture;

Deposition

• For public access – free of charge;

• For patenting - EUR 426.86 + VAT per culture;

• Confidential storage of microorganisms, where the depositor retains all ownership rights (safe-deposit);
  EUR 35.57 + VAT per culture per year;
