Overview
ISO 20309:2025 - Biotechnology - Biobanking - Requirements for deep-sea biological material provides standardized requirements for the biobanking lifecycle of deep-sea biological material intended for biomolecular processing (e.g., nucleic acids, proteins, metabolites). The standard covers collection, on‑vessel processing, preservation, transport, storage and associated information management for samples derived from ocean areas at depths ≥ 200 m. It is intended for organizations performing research and development on deep‑sea genetic resources and complements general biobanking requirements.
Key topics and technical requirements
The standard defines practical, quality-focused requirements around:
-
Collection planning
- Documented collection plan stating purpose, location, depth, timing, equipment, contingencies and sequences to meet intended uses.
- Risk assessment and mitigation measures proportionate to likely hazards and impacts.
-
On‑vessel processing
- Procedures for preparing equipment, avoiding cross‑contamination, and sequencing processing workflows on marine vessels and platforms (landers, submersibles, bioboxes).
- Competence requirements for personnel involved in collection, sampling and processing.
-
Preservation and downstream suitability
- Guidance on preservation approaches and treatment methods tied to downstream biomolecular applications (annexes provide examples).
- Emphasis on maintaining molecular integrity for nucleic acid, protein and metabolite analyses.
-
Transport and packaging
- Requirements for packaging, transport conditions and traceability to preserve sample quality between vessel, laboratory and biobank.
-
Storage, monitoring and traceability
- Storage condition management, monitoring and recordkeeping to ensure long‑term usability.
- Robust sample traceability and metadata capture for provenance and reproducibility.
-
Biorisk and quality management
- Integration with ISO 20387 (general biobanking) and documented biorisk management (e.g., ISO 35001) where applicable.
Applications and who uses it
ISO 20309:2025 is applicable to:
- Marine research institutions and university labs collecting deep‑sea specimens for genomics, proteomics and metabolomics.
- Biobanks and sample repositories storing deep‑sea-derived molecular material.
- Biotechnology and pharmaceutical companies exploiting deep‑sea bioresources for discovery and product development.
- Oceanographic expeditions, ROV/AUV operators and contract research organizations involved in deep‑sea sampling.
Practical benefits include improved sample quality for downstream biomolecular analysis, standardized metadata for reproducibility, and clearer transport/storage practices that protect molecular integrity.
