  • “Good” rating in bank user satisfaction

2023-2025

  • Securing of 6,000 species in material diversity
  • Maintenance of Quality Management System certification
  • Recognition of bioresource bank as international standard
  • Achievement of “Excellent” in bank user satisfaction

2026-2028

  • Securing of 7,000 species in material diversity
  • Maintenance of Quality Management System certification
  • Maintenance of recognition of biological resource bank as international standard
  • Maintenance of “Excellent” in bank user satisfaction

Target Project 1. Expansion of Freshwater Species List

  • Expansion of the national species list through identification of freshwater species not yet revealed (discovery of new/unrecorded species)
  • Strengthening the function of the national key asset, i.e., the storage facility, through quantitative and qualitative expansion of biological specimens held
  • Establishment of digital images of stored biological specimens to enhance permanent preservation and utilization

Securing freshwater plants, animals, and microorganisms through surveys of freshwater rivers and unique habitats (caves, wetlands, brackish water, etc.)

New species

  • P. danyangensis n. sp.
  • Wetland planarian
  • Lacibacter nakdongensis
  • Emericelliopsis koreana

Specimens

  • Kamimuria coreana Ra, Kim, Kang and Ham, 1994
  • Radix auricularia (Linnaeus, 1758)
  • Tobrilus wesenbergi (Micoletzky, 1925)
  • Cymbopleura opicalata

Operation of freshwater organism specimen-specialized storage facility

  • Securing and storing freshwater specimens (goal: 1 million by 2030)
  • Operation of freshwater specimen-specialized storage facility and regular inspection of preservation status
  • Promotion of digitization for preservation and expanded utilization of biological specimen information
  • Broad utilization through content development of digital images of biological specimens

Target Project 2. Expansion of Securing and Sharing Freshwater Biological Resources

  • Strengthening support for national utilization of freshwater life research resources
  • Improving the international status of the freshwater biological resource bank to enhance user trust
  • Increasing satisfaction of freshwater biological resource bank users through expanded communication with customers

Securing of biological resources: Cultures and extracts

  • Sample collection
  • Pure isolation
  • Identification

Stable preservation management according to resource characteristics

  • Freshwater algae: live preservation
  • Bacteria, fungi, and natural substances: cryopreservation
  • Freeze-dry preservation
