Szabo Corbacho, M. (author), Sharma, Pragnya (author), Míguez, Diana (author), de la Sovera, Victoria (author), Brdjanovic, Damir (author), Etchebehere, Claudia (author), Garcia, H. (author), van Lier, J.B. (author)The study investigated the effects of long-chain fatty acids (LCFA) on anaerobic sludge treating lipid-rich wastewater. It involved batch experiments with three sludge samples: two acclimated to lipids and one non-acclimated. The experiments aimed to observe the degradation of LCFA, specifically oleate and palmitate, by dosing them at...journal article 2024

(author)Microplastics (MPs), miniscule plastic particles measuring less than 5 mm in size, have become a concern in terrestrial ecosystems, with primarily agricultural and wetland soils being the soils with highest plastic loadings. The adverse effect of MPs might lead to changes in physicochemical and biological characteristics of soil including...review 2024

Atasoy, M. (author), Scott Jr, William T. (author), Regueira, Alberte (author), Mauricio-Iglesias, Miguel (author), Schaap, Peter J. (author), Smidt, Hauke (author)In recent years, there has been growing interest in harnessing anaerobic digestion technology for resource recovery from waste streams.

Diaz-Colunga, Juan (author), Skwara, Abigail (author), Vila, Jean C.C. (author), Bajic, D. (author), Sanchez, Alvaro (author)The many functions of microbial communities emerge from a complex web of interactions between organisms and their environment. This poses a significant obstacle to engineering microbial consortia, hindering our ability to harness the potential of microorganisms for biotechnological applications. In this study, we demonstrate that the collective...journal article 2024

Garcia Rea, V.S. (author)Anaerobic digestion (AD) is a biochemical process in which organic matter is converted into biogas in a series of biochemical reactions. The development of high-rate anaerobic reactors (HRAR) led to the breakthrough of full-scale applications of AD for the treatment of industrial wastewater. HRARs, such as the upflow anaerobic sludge blanket ...doctoral thesis 2023

Allaart, M.T. (author)One of the main challenges society currently deals with is the depletion of fossil fuels. To navigate this issue, we must embrace the concept of circularity and turn waste into a resource. Waste streams are omnifarious and their conversion into new chemical building blocks is not always trivial. Luckily, we can take a look at nature’s problem...doctoral thesis 2023

Christofi, Andreas (author)Dating back to 10,000 B.C.E., fermentation has served as a vital tool primarily for food preservation. In the nineteenth century, Louis Pasteur put forth the proposition that the occurrence of fermentation is predominantly facilitated by the presence of microorganisms. Pasteur’s discovery spurred comprehensive studies on microorganisms,...master thesis 2023

Martinez-Rabert, Eloi (author), Sloan, William T. (author), Gonzalez Cabaleiro, R. (author)Hypothesis and theory-based studies in microbial ecology have been neglected in favour of those that are descriptive and aim for data-gathering of uncultured microbial species. This tendency limits our capacity to create new mechanistic explanations of microbial community dynamics, hampering the improvement of current environmental...review 2023

Deng, Z. (author), Muñoz Sierra, Julian (author), Ferreira, Ana Lucia Morgado (author), Cerqueda Garcia, D. (author), Spanjers, H. (author), van Lier, J.B. (author)Treating protein-rich wastewater using cost-effective and simple-structured single-stage reactors presents several challenges. In this study, we applied an anaerobic sequencing batch reactor (AnSBR) to treat protein-rich wastewater from a slaughterhouse. We focused on identifying the key factors influencing the removal of chemical oxygen...journal article 2023

Ahmadi, Navid (author), Abbasi, Mona (author), Torabian, Ali (author), van Loosdrecht, Mark C.M. (author), Ducoste, Joel (author)We investigated the transformation of four pharmaceuticals (Diclofenac, Naproxen, Ibuprofen and Carbamazepine) in a moving bed biofilm reactor subjected to different COD/N ratios in four experimental phases. The shift from medium to high range COD/N ratio (i.e., 5:1 to 100:1) intensified the competition between heterotrophs and nitrifying...journal article 2023

Han, Fei (author), Zhang, Mengru (author), Li, Zhe (author), Liu, Zhe (author), Han, Yufei (author), Li, L. (author), Zhou, Weizhi (author)Marine microorganisms have an inherent advantage in the treatment of saline wastewater due to their halophilic properties. Ammonium assimilation is the most important and common nitrogen conversion pathway in the ocean, which means that it may be a suitable nitrogen removal strategy under high salinity conditions. However, the targeted...journal article 2023
