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.

Are Sustainability and Safety Incompatible?

In the world of biotechnology, safety and sustainability might sometimes be at odds. When conflicts arise, decision-makers must carefully weigh the trade-offs, addressing potential risks and ethical concerns in order to make informed choices. According to two TU Delft professors, safety and sustainability need to go hand in hand to ensure that biotechnological processes and products are developed and managed responsibly. text Heather Montague Risks and responsibilities With the rise of the circular economy, finding ways to use waste for other purposes has become a hot topic. But there are risks involved, says Lotte Asveld , Associate Professor of Ethics & Biotechnology at TU Delft. “People have high standards when it comes to using wastes as resources. Anything that comes out of the sewer doesn’t feel very comfortable to have in your house.” In that sense, she sees a clash between sustainability and safety but also believes they should be combined. “We can’t make everything 100% safe, but we should look towards what risks people find acceptable.” Societal acceptance of using waste as a resource requires that regulations and responsibilities be well aligned. We also need to reevaluate the way we learn about risks, according to Asveld. She notes that biotechnology is strictly regulated, but in the chemical industry, companies themselves are responsible for learning about and identifying risks. “As new risky substances keep emerging, what needs to happen in the innovation ecosystem to make sure that these responsibilities have a place?” Learning about these risks is not always an inherent part of a company’s structure and that needs to change. “My objective is to make sure that safety is something that we talk about, that we don’t take for granted, that we discuss amongst each other; what does it mean, how can we achieve it, and how do we see our responsibility to society and achieving safety?” The future is green The term ‘green chemistry’ was introduced some thirty years ago, according to Ulf Hanefeld , Professor of Biotechnology at TU Delft’s Faculty of Applied Sciences. The aim is to enable society to make what is currently made, or alternatives, in a sustainable and safe manner. “So how can I make the compounds that we as a society think we need in a sustainable manner, starting from readily available materials, performing reactions that are inherently safe,” says Hanefeld. “For me, safety and sustainability go hand in hand.” There are advantages and opportunities that come along with green chemistry. If you take all the starting materials, make only products out of it and don’t generate any waste, that results in higher profit. And there is also an opportunity to develop a new chemistry. “Consider that our current chemistry always starts from petrochemicals, which are very low in terms of functionality,” Hanefeld explains. “If you use sustainable materials like sugars or lignin or plant waste, that is always highly functionalised. Because we have a new type of starter material, we’re doing it all new, and it is a chance to develop it safe from the start. Download article Download article

Jack Pronk receives the 2024 Novozymes Prize

The Novo Nordisk Foundation proudly announces Professor Jack Pronk as the recipient of the 2024 Novozymes Prize for his groundbreaking contributions to industrial biotechnology. His transformative research in yeast physiology and metabolic engineering has not only revolutionised biofuel and chemical production but has also provided critical solutions to longstanding challenges in sustainable bioprocesses. At the turn of the century, as the world faced the looming climate crisis spurred by fossil-fuel consumption, the importance of alternative fuels became increasingly apparent. Bioethanol emerged as a promising solution, yet its production from non-food sources posed significant challenges. “It had been a dream for decades to establish a biobased economy utilising microorganisms. An example is producing fuel ethanol from sugar using yeast, which efficiently converts glucose into ethanol. However, this approach was controversial because unlimited expansion could lead to competition with food production,” explains Jack Pronk, Professor and Head of the Department of Biotechnology at Delft University of Technology (TU Delft) in the Netherlands. Although yeast could efficiently turn sugars from fruits and other edible sources into bioethanol, the metabolism of sugars from agricultural waste streams posed a critical hurdle for economical bioethanol conversion, since traditional yeast strains struggled to utilise pentose sugars, which are abundant in agricultural residues. In a groundbreaking collaboration with fellow microbiologist Huub Op den Camp from Radboud University Nijmegen, Jack Pronk discovered a potential solution in an unlikely source – the anaerobic fungus Piromyces sp. strain E2, isolated from the faeces of an Indian elephant. This fungus harboured a xylose isomerase gene that held the key to unlocking the pentose challenge. “The result initiated years of research, increasingly involving collaboration with the company DSM,” states Jack Pronk. “Through this process, baker’s yeast was adapted for processing pentose sugars from agricultural waste streams.” “Jack Pronk is one of Europe’s foremost leaders in innovative, sustainable biotechnology using microbes for environmentally friendly conversion of waste streams into biofuels and fine chemicals. The fundamental research and the knowledge generated about the functioning of yeast and fungi from Jack Pronk’s laboratory has been the basis for a wide range of commercial applications with clear societal impact, as demonstrated by their full-scale industrial implementation. The Novo Nordisk Foundation is proud to recognise Jack Pronk’s excellence in research with the 2024 Novozymes Prize,” says Professor Mads Krogsgaard Thomsen, CEO of the Novo Nordisk Foundation. By 2010, the modified yeast could efficiently convert the most important sugars from plant residues into ethanol, paving the way for sustainable biofuel production technologies. Despite setbacks in large-scale implementation, Jack Pronk believes that the production of ethanol from agricultural residues will make a comeback. Ethanol is not only useful as a transport fuel but also as a precursor for compounds ranging from ethylene to aviation fuel. “I do see a future for ethanol, produced by low-emission technologies, as a generic feedstock for production of food protein, pharmaceuticals and fine chemicals. There is huge potential for its production from agricultural residues. I am convinced that genetically modified microorganisms, be they yeasts, bacteria or fungi, will enable cost-effective and sustainable ethanol production from these feedstocks.” The 2024 Novozymes Prize therefore celebrates Professor Jack Pronk’s exceptional contributions to industrial biotechnology, highlighting his innovative solutions to longstanding challenges and his enduring commitment to sustainable bioprocesses. His work exemplifies the transformative potential of biotechnology in addressing global challenges and building a more sustainable future. “The advances Jack Pronk has made, especially with using yeast, are based on exceptionally deep knowledge of physiology and metabolism, rooted in rigorous fundamental research. His superb understanding of how a yeast cell operates has directly translated into Jack being able to exploit yeast cells as industrial-level factories for producing fuels and chemicals. He clearly is a world leader in industrial biotechnology and fermentation science, with a specific focus on developing sustainable bioprocesses that help to reduce waste streams and carbon footprint,” concludes Professor Detlef Weigel, Chair of the Committee on the Novozymes Prize.

Robust reactor design to simplify biomolecule production

TU Delft and Delft Advanced Biorenewables (DAB) are engaged in a long term development of a low cost and robust integrated bioreactor especially for the production of biofuel precursors as well as chemical and other building blocks that have a common ‘oily’ behaviour of immiscibility with aqueous phases such a fermentation broth. Research of Rita da Costa Basto focused on the important elements of the integrated production process of hydrocarbons by the fermentative route such as coalescence and phase separation. She has defended her PhD thesis on this topic Thursday 11 January 2024 in Delft.
