de Graaff, D.R. (author), van Loosdrecht, Mark C.M. (author), Pronk, M. (author)Many sources of wastewater contain sulfides, which can cause excessive growth of filamentous bacteria such as Thiothrix sp. resulting in bulking sludge in conventional activated sludge systems. Granular sludge systems could potentially also suffer from the growth of filamentous bacteria. Uptake of easily degradable COD by the relatively slow...journal article 2020

(author), Pabst, Martin (author)Nonulosonic acids, commonly referred to as sialic acids, are a highly important group of nine-carbon sugars common to all domains of life. They all share biosynthetic and structural features, but otherwise display a remarkable chemical diversity. In humans, sialic acids cover all cells which makes them important for processes such as cellular...review 2020

(author)Anammox (anaerobic ammonium oxidation) bacteria are important for the nitrogen cycle in both natural environments and wastewater treatment plants. These bacteria have a strong tendency to grow in aggregates like biofilms and granular sludge. To understand the formation of anammox aggregates, it is required to unravel the composition of the...journal article 2020

Vasilakou, E. (author), van Loosdrecht, Mark C.M. (author), Wahl, S.A. (author)Background: Microbial metabolism is highly dependent on the environmental conditions. Especially, the substrate concentration, as well as oxygen availability, determine the metabolic rates. In large-scale bioreactors, microorganisms encounter dynamic conditions in substrate and oxygen availability (mixing limitations), which influence their...journal article 2020
