of magnetic field on enzymatic activities in drinking water biofilm

BSc or MSc Thesis/internship
Starting date: preferably October 2024,
Duration: 6 months
Location: Wetsus, European centre of excellence for sustainable water technology, at Leeuwarden

There are a few possibilities for allowances:
– The allowance for students is €200. The student can apply for ‘Wetsus Grant’ allowance (€200 extra; an internal committee decides if the allowance will be granted).
– Students can apply for Erasmus; (if the Erasmus grant is less than €400, the student can apply for the Wetsus Grant).
– Erasmus
*The Wetsus Grant allowance is not guaranteed and must be approved by the Grant Committee.

Biofilm formation in drinking water distribution (DWD) pipes is responsible for a wide range of water quality and operational problems. In the water industry, it has been frequently observed that magnetic fields, as a sustainable and additive-free technology, can greatly preserve drinking water quality and reduce the fouling tendency. However, despite the numerous field and laboratory observations, there is lack of solid explanation of the mechanism on how magnetic field can affect biofilm growth in DWD.

Recently, the effect of magnetic gradients on drinking water bacteria and microbial calcium carbonate precipitation processes are experimentally verified. It is suggested that specific enzymatic activities of bacteria are influenced by the magnetic fields. Therefore, the aim of this proposed master project is to investigate the effect of magnetic fields on enzymatic kinetics.

Research challenge
Pure culture bacteria isolated from drinking water will be used to assess the effect of magnetic fields on the enzymatic activity. Different molecular/biochemical method will be developed and applied to measure the reaction rate of amino acid metabolism under the influence of magnetic fields.



We are looking for a candidate studying a BSc or MSc program in the field of microbiology, molecular biology or biochemistry. The project has a minimum duration of 6 month. Starting date is preferably in October 2024.

Due to the visa related issues, only 1) EU citizens enrolled in any university or 2) non-EU citizens already living in the Netherlands and enrolled in a Dutch university will be allowed to work as internship/thesis student.

The internship includes a monthly allowance of 200 euro per month for the students without Erasmus scholarship. In addition, the student can apply for “Wetsus Grant” allowance ( 200 euros extra; an internal committee decides if the allowance will be granted). The Wetsus Grant allowance is not guaranteed and must be approved by the Grant Committee.

Towards an economy of value preservation | By Niels Faber


The realisation of a circular economy has thus far unfolded under the assumption that it would fit within existing economic arrangements. In practice, we witness many circular initiatives struggling to give shape to their ambitions, let alone develop to maturity. These past months, various material recycling organisations terminated their activities, seeing virgin alternatives from other parts of the world flooding the market at prices against they cannot compete. If the transition towards a circular economy (i.e. an economy of value preservation) is to be taken seriously, a new perspective on value in our economic system seems unavoidable, as the rewriting of the rules of the economic game. At this moment, current perceptions of value stand in the way of this transition both at micro as well as macro levels. Several contours for a collective exploration of new directions of value and economic configuration that foster circular transition will be addressed.

Searching Innovation for the Common Good | By Cees Buisman


In his key note he will conclude after a life of innovations that it is impossible that humanity will stay within the save planetary boundaries with innovation only. We should be more critical about the behaviour of the rich population in the world and more critical about new innovations that prove to be dangerous, like the PFAS crisis shows at this moment. In his keynote he will investigate how to look at the world that can stay within the save planetary boundaries, how should we change ourselves? It is clear if we only talk about the words of science and systems we miss the essential words of how we should cooperate and change ourselves. And his search for coherent save innovations. Which innovations will be save and will lead to a fair and sustainable world? And will lead to a world we want to live in.

Future-fit economic models: What do they have in common – how can they join forces? | By Christian Felber


There is a growing number of new sustainable, inclusive, cohesive, participatory, just and humane economic models. A possible next step in the discourse about them is the comparative analysis in order to find out key commonalities, potential synergies, and “requirements” for a future-fit economic model. The author and initiator of the Economy for the Common Good provides an overview of these „new sustainable economic models“ and compares them according to underlying values, principles, and practical ways of implementation. The keynote addresses the cooperative spirit of the conference and prepares the ground for its public highlight on the eve of June 3rd, the round table with representatives of diverse future-fit economic models.

The era of postgrowth economics | By Matthias Olthaar


The scientific debate on whether economies should always continue to grow increasingly becomes a political and societal debate. On the one hand further growth for the most affluent countries seems neither possible nor valuable, but on the other hand there is still lack of understanding and knowledge what a non-growing economy should look like and could best be governed. In this lecture we discuss various policy measures that can be realistically implemented, take into account government finances and aim at a higher quality of life despite a non-growing economy.

Democratic principles for a sustainable economy | By Lisa Herzog


Democracy is under pressure, and less and less able to stir the economy into a sustainable direction. Therefore, to stabilize democracy and to make possible the socio-ecological transformation of the economy, democratic principles need to be implemented directly in the economy. This is not only a matter of morality, but also has practical advantages. Democratizing the economy can increase legitimacy and take advantage of the “knowledge of the many” to accelerate the transformation. Democratic practices, especially deliberation, allow bringing together different forms of knowledge, which is crucial for the local implementation of principles of social and ecological sustainability. This talk explores what this idea means in more concrete terms, from democratic participation in the workplace to the democratization of time.

Market, state, association, and well-being. An historical approach | By Bas van Bavel


Over the past decades, markets have conventionally been seen as the best instrument to stimulate economic growth and enhance prosperity and well-being. The automatic link between markets and economic growth is increasingly questioned, however, as well as the automatic link between economic growth and enhancement of well-being. This has led to attempts to capture well-being development more directly than through GDP per capita figures and has produced a more variegated picture of well-being growth. Also, this has led to a shift of focus to other coordination systems than the market, as primarily the state but increasingly also the association. Analyses of the historical record suggest that especially the latter could be a vital component in future well-being.
