Long-Read Microbial Genomics
PhD School at the Faculty of SCIENCE at University of Copenhagen
This is a toolbox course where 80% of the seats are reserved for PhD students enrolled at the Faculty of SCIENCE at UCPH and 20% of the seats are reserved for PhD students from other Danish Universities/faculties (except CBS). Seats will be allocated on a first-come, first-served basis and according to the applicable rules.
Anyone can apply for the course, but if you are not a PhD student at a Danish university (except CBS), you will be placed on the waiting list until enrollment deadline. After the enrollment deadline, available seats will be allocated to applicants on the waiting list.
Aim and Content
Long-read sequencing using Oxford Nanopore Technologies (ONT) has rapidly transformed microbial genomics by enabling complete genome reconstruction, including plasmids, and improved taxonomic classification. This intensive one-week course provides hands-on training in nanopore-based analysis of both single bacterial isolates and mixed microbial communities (metagenomics).
Participants will gain practical experience in DNA library preparation using both Native and Rapid ONT protocols, followed by sequencing and downstream analysis of long-read data. The course emphasizes working directly with raw nanopore data (pod5/fastq) and applying state-of-the-art tools for genome assembly, strain resolution, and taxonomic classification.
For isolate genomics, participants will assemble complete bacterial genomes and plasmids using tools such as Hybracter and recover high-quality genomes with MMLong2. Taxonomic classification will be performed using GTDB-based approaches. For metagenomic samples, participants will learn to classify microbial communities using Metabuli.
The course is designed for PhD students and industry professionals and combines lectures, laboratory work, and computational exercises.

Target Group
The course is primarily aimed at PhD students and early-career researchers working in microbial genomics, bacterial genetics, metagenomics, and DNA sequencing technologies. It is also highly relevant for laboratory technicians and professionals from industry and private companies who are involved in sequencing-based workflows, microbiome analysis, or bioinformatics data analysis.
Recommended Academic Qualifications
Participants should have a background in microbiology, molecular biology, biotechnology, bioinformatics, food science, or environmental science. Basic familiarity with DNA sequencing
technologies and microbial genomics is recommended.
Research Area
The course is relevant to research within microbial genomics, microbiology, molecular biology, biotechnology, bioinformatics, food science, and environmental science. It is particularly suited
for research focusing on long-read sequencing, genome assembly, metagenomic analysis, microbial ecology, and genomics-driven approaches in both academic and industrial settings.
Teaching and Learning Methods
The course combines theoretical instruction and practical training to provide participants with both conceptual understanding and hands-on experience.
Instruction includes:
• Lectures (22 hours): Introduction to long-read sequencing technologies (Oxford Nanopore), microbial genomics, genome assembly, and taxonomic classification approaches.
• Laboratory Sessions (7.5 hours): Hands-on training in DNA quality assessment, library preparation, and operation of nanopore sequencing platforms.
• Computational Exercises (13 hours): Guided analysis of long-read sequencing data, including preprocessing, genome assembly, taxonomic classification, and metagenomic analysis using relevant bioinformatics tools.
• Course Preparation (20 hours): Pre-reading and familiarization with sequencing technologies and basic bioinformatics concepts.
• Theoretical Exercises (20 hours): Independent work where participants analyze provided datasets and prepare a short report describing workflows, results, and interpretation.
The format ensures the workload equivalent to 3 ECTS (82.5 hours total).
Type of Assessment
• Assemble a complete bacterial genome from long-read sequencing data using relevant bioinformatics tools.
• Perform gene prediction and functional annotation of the assembled genome.
• Document the analysis workflow, including key steps, tools, and parameters used.
• Prepare a short-written report that presents a walkthrough of the analysis pipeline.
• Interpret and discuss the results, including raw data quality, assembly outcomes, and biological relevance.
• Assessment will be conducted on a pass/fail basis, based on the quality and completeness of the submitted report, as well as active participation during the course.
