Member holdings

KPD, the Collection of Plasmids and Microorganisms, comprises ca. 1,400 strains, of which more than 600 are available for researchers from the industry and academia.

Our holdings include:

. recent multi-drug resistant clinical isolates

. environmental strains

. microorganisms with potential application in molecular biology, biotechnology and bioengineering

. laboratory strains and plasmid vectors used as tools in molecular biology and genetic engineering

. E. coli mutants and new genetic constructs used for research on the regulation of cellular processes and stress response in prokaryotes

. microbial strains for teaching purposes

. natural plasmids

. cloning/ overproduction vectors

Services offered

  • Distribution of strains for different purposes (basic research, education, R&D, commercial applications)
  • Supply of isolated plasmid/genomic DNA
  • Identification of bacteria (via MALDI TOF analysis, 16S RNA gene analysis, microbial phenotyping using OmniLog system)
  • Preservation of biological material under the Budapest Treaty (Patent deposits). The KPD is recognized as an International Deposit Authority (IDA)


  • Taxonomy
  • Characterization and preservation of bacterial strains
  • Plasmid copy number determination by ddPCR
  • Bioprospecting of microbial resources
  • Characterisation of prokaryotic proteins (analysis of thermal stability, activity and binding affinity possible, application

KPD has been actively involved in various international research projects focused on bioprospecting of microbial resources, particularly from extreme environments. KPD is open to collaborating with researchers in joint projects.

Quality Management System

KPD makes every effort to ensure the highest possible quality of deposited biological material, which undergoes quality control for viability, purity and authenticity, and data accuracy.

The traceability of the process of depositing, cultivation/ replication, preservation, and distribution of the biological material is entirely followed and documented.

KPD operates in compliance with international guidelines, including World Federation for Culture Collection (WFCC) guidelines for culture collections, the Common Access to Biotechnology Resources Information (CABRI) Guidelines and Organization for Economic Co-operation and Development (OECD) Best Practice Guidelines for Biological Resource Centers.
