Thesis topic:
Bioavailability and species transformations of micronutrients in (bio)reactors used for resource recovery and water reuse
Motivation
Trace elements, such as Co, Ni and Fe are crucial constituents of enzymes, and as such, they affect the metabolism of microorganisms in anaerobic reactors. When trace elements deficiency is present, the proper synthesis of enzymes can be hindered, resulting in lower microbial activity and thus decreased methane production. Even though in practice, trace elements are often present in sufficient amounts, but the metal fraction that is bioavailable to the microorganisms is comparably small due to precipitation of metals in the anaerobic systems.
Solution
The objective of this topic is to find the most appropriate method to measure bioavailable metals in the anaerobic sludges and relate it to their microbial activity. Furthermore, the goal is to be able to predict if metal deficiency is present, based on the chosen method. For that, different techniques such as diffusive gradients in thin films (DGT) and ultrafiltration will be tested and also a deeper insight into fractionation of metals depending on the operational parameters will be investigated.
