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:

Mark van Loosdrecht wins Novozymes Prize for 25 years of revolutionary wastewater treatmentThe development of new technologies for biological wastewater treatment is turning our view of sludge upside down. Microbiologist Mark van Loosdrecht receives the 2022 Novozymes Prize for his pioneering work in copying and reusing nature’s mechanisms in wastewater treatment and resource recovery. Van Loosdrecht: “Treating wastewater will become good business in the future.”

Super-fast technique measures heme enzyme reaction as it happensResearchers from TU Delft found an unexpected new enzyme intermediate at work in enzymes that contain heme, a cofactor that’s vital for many processes in our body such as the breaking down of toxins in the liver. The researchers used new, rapid techniques, which are less invasive than existing methods. The results, published in ACS Catalysis, increase our understanding of heme proteins and enzymes and how they can be engineered.

Making artificial leather while processing wastewaterLeather is a strong product but has been getting bad press lately due to the fact that it is made of animal skins and the production process is a burden on the environment. The TU Delft student team WaterSkins has come up with a very sustainable alternative: artificial leather made during the treatment of wastewater.

Cable bacteria: Living electrical wires with record conductivityBacteria that power themselves using electricity and are able to send electrical currents over long distances through highly conductive power lines. It almost sounds like the way we charge our TVs and refrigerators, and may seem hard to believe, but it is a recent discovery by a team of scientists from the University of Antwerp (Belgium), Delft University of Technology (Netherlands) and the University of Hasselt (Belgium). Centimeter-long bacteria from the seafloor contain a conductive fiber network that operates in comparable way to the copper wiring that we use to transport electricity. The highly conductive fibers enable a completely new interface between biology and electronics, providing a prospect for new materials and technology.
