Biotechnology

Innovation is crucial to fulfil the potential of industrial biotechnology for sustainable production of fuels, chemicals, materials, food and feed. Similarly, scientific and technological advances in environmental biotechnology are needed to enable novel approaches to water purification, and ‘waste-to-product’ processes thus contributing to a circular economy. Increased fundamental knowledge encompassing enzymes, microorganisms and processes are essential for progress in this field. The Department of Biotechnology covers this research area and, based on new insights, selects, designs and tests new biobased catalysts, micro-organisms, and processes.

The department encompasses five research sections:

BEI Best MSc Graduate 2022: Raman van Wee!

BEI Best MSc Graduate Awards 2022 Since 2020, Delft Bioengineering Institute (BEI) organizes a cross-campus competition for MSc students who performed remarkably well at their graduation projects in bioengineering. This year, nine very impressive theses were submitted. After a strenuous review and discussion, the jury finally agreed that Raman van Wee (MSc Nanobiology), Nastaran Barin (MSc Mechanical Engineering) and Juancito van Leeuwen (MSc Nanobiology and Biomedical Engineering) have delivered the most innovative, interdisciplinary bioengineering projects of 2022. On top of eternal fame, they will receive personal cash prizes of €1000, €500 and €250. 1. Raman van Wee (MSc Nanobiology) Thesis: Using DNA Nanotechnology and Fluorescence for Single-Molecule Protein Identification Supervisor: Chirlmin Joo (TNW/BN) Chirlmin Joo: “Raman is absolutely outstanding! He grasped the whole picture of the project in less than a month and was much motivated and capable to lead the project by making a grand plan and executing it promptly. Throughout his master’s project, he demonstrated original and independent thinking, which has helped revealing the potential of the new technology. It has also resulted in new methods in my group for protein labelling and single-molecule studies of DNA-tagged proteins, which will be essential for the next phase of the project. The quality and quantity of his data exceeded the expectation. He produced two research articles (one of them published in iScience) as a co-author as well as a review paper as a leading author.” 2. Nastaran Barin (MSc Mechanical Engineering) Thesis: 3D-Engineered Scaffolds to Study Primary Glioblastoma Microtube Formation and EGFR Expression Supervisors: Angelo Accardo (TU Delft), Pim French (Erasmus MC) Angelo Accardo: “The work performed by Nastaran is a perfect example demonstrating the added value of combining two different disciplines. Regardless of her engineering background, Nastaran showed immediately an innate predisposition also for the biological part of this study (cell culture, confocal imaging and advanced image data analysis tasks) which is a remarkable feat. The results of her MSc thesis were awarded with a final grade of 9/10. After obtaining her Master’s at TU Delft, she embarked in a PhD program at Erasmus MC in collaboration with TU Delft under my and Pim French’s supervision. Having a mechanical engineering background, undertaking a PhD in a medical center like Erasmus MC is the proof of how Nastaran can easily bridge these two environments, ways of thinking and required skill-sets. Her work has been recently published in Small, one of the most prestigious interdisciplinary journals in the field of bioengineering, and even featured the front cover.” 3. Juancito van Leeuwen (MSc Nanobiology and Biomedical Engineering) Thesis: Engineering of protein based phononic crystals for contrast-enhanced ultrasound imaging Supervisors: David Maresca (TNW/ImPhys), Valeria Garbin (TNW/ChemE) David Maresca: “Juancito has achieved and sustained an excellent level of research in the field of Biomolecular Ultrasound over the year that he has spent in my laboratory and that of Valeria Garbin. He is truly one of the most talented and hardworking master students I have worked with so far. In 2021, Valeria and I were awarded a BioDate MSc project entitled “Droplet‐based self‐assembly of gas vesicles for novel acoustic biosensors”, and in September, Juancito joined my research group as a MEP student to pursue this research project. Juancito’s research combined aspects of ultrasound imaging physics, molecular engineering, and microfluidics. It was truly an interdisciplinary research endeavour. He demonstrated that the assembly of protein-based ultrasound contrast agents could boost their acoustic scattering by fourfold. Based on this finding, he designed and tested microfluidic chips for the high-throughput fabrication of echogenic protein assemblies, that could ultimately serve as long circulating ultrasound contrast agents for neuroimaging. His research required to work proficiently with ultrasound imaging scanners, genetically encoded proteins, cryo-EM microscopes, microfluidic systems and phase contrast microscopes in multiple labs across campus. He defended his thesis for a double degree MSc and graduated Cum Laude.”

Investment of 14 million for better use of micro-organisms

Microorganisms can perform many processes useful to mankind, such as converting milk to cheese, keeping human and animal intestines healthy, and cleaning our water and environment. Together with Wageningen University & Research and Delft University of Technology, the Dutch Research Council (NWO) will invest almost 25 million euros in a research facility for investigating mixed microbial communities and their application. The research facility – called UNLOCK (UNLOCKing Microbial Diversity for Society) - consists of equipment and human resources that will be used to gather knowledge on micro-organisms effectively. Team-players Micro-organisms are natural team-players. They are essential for human health via the intestinal microbiome, and for processes like waste water treatment, soil fertilization for plant growth, and food preparation such as cheese or beer through fermentation. However, even though natural and man-made ecosystems are characterized by an enormous microbial diversity, research on microbial communities and their application in biotechnological processes historically has been conducted with a very limited number of strains isolated from these ecosystems. We are currently using no more than 1 per cent of the microbiological potential available in nature Ecosystem Besides that, research on micro-organisms usually focuses on a limited number of specific strains of organisms, while in nature micro-organisms always operate in ecosystems consisting of different species. ‘You could compare it to building a house’, says Robbert Kleerebezem, who is the Delft scientist involved in the project. ‘To build one, you need different experts, like masons, roofers, electricians and plumbers. You can pick out any one of them, and study what they are doing, but that won’t tell you anything about what the resulting house will look like.’ Eagerly awaited Wageningen and Delft have launched the new research facility UNLOCK to study mixed microbial cultures extensively. Various sub-areas of research will be integrated through UNLOCK. This development has been eagerly awaited by researchers studying mixed microbial communities. This integration will make significant scientific and societal breakthroughs possible. NWO's approval will make a 14.5 million euro funding available for the next decade, of which a third will go to TU Delft. Automated cultivation of ecosystems "In Delft we will be working on making automated systems in which we can cultivate ecosystems of micro-organisms in mixed compositions, and monitor them’, says Kleerebezem. ‘This makes UNLOCK a unique facility, because we will be able to do comparative studies on a large scale and in an efficient manner, in order to gain important insights into the interactions between micro-organisms’. New persepectives A total of 24.8 million euros will be invested in UNLOCK. Lead petitioner, Prof. Hauke Smidt is delighted with the approval. ‘This is fantastic. UNLOCK opens up entirely new perspectives for the discovery of new micro-organisms and ground-breaking research on mixed microbial communities’. UNLOCKing Microbial Diversity for Society In UNLOCK, Wageningen and Delft have joined forces towards full integration of all relevant fields of expertise in four complementary platforms: · The Biodiscovery platform (WUR-Microbiology) allows its users to discover and characterize new micro-organisms. In addition, there is a processing unit that allows for fully automated unlocking of biological samples for biomolecular analysis. · The Modular bioreactor platform (WUR-Environmental Technology) facilitates research for sustainable solutions to environmental issues, such as the degradation of (micro) pollutants, sustainable energy generation and reclaiming resources from complex waste streams. · With the Parallel Bioreactor platform (TU Delft -Biotechnology), users can simultaneously conduct dozens of experiments in bioreactors for comparative analysis on how process variables affect system development. · The FAIR data platform (WUR-Systems & Synthetic Biology) takes care of the storage, processing and interpretation of large quantities of data flowing from the experimental systems in a cloud-based infrastructure based on the FAIR principles (Findable, Accessible, Interoperable, Reusable). Large-scale Scientific Infrastructure NWO has allocated a total of 93 million euros to seven projects. The Ministry of Culture and Education makes funds available to NWO for the National Roadmap for a Large-scale Scientific Infrastructure. These funds enable the building and overhaul of essential research infrastructures. The awarded scientific infrastructures are of critical importance to innovative scientific research, and as a stimulus for economic and societal innovations across all scientific disciplines.
