Feasibility of packed-bed trickling filters for partial nitritation/anammox : effects of carrier material, bottom ventilation openings, hydraulic loading rate and free ammonia Universiteit Gent Universiteit Antwerpen
This study pioneers the feasibility of cost-effective partial nitritation/anammox (PN/A) in packed-bed trickling filters (TFs). Three parallel TFs tested different carrier materials, the presence or absence of bottom ventilation openings, hydraulic loading rates (HLR, 0.4-2.2 m3 m- 2 h-1), and free ammonia (FA) levels on synthetic me-dium. The inexpensive Argex expanded clay was recommended due to the similar nitrogen removal rates as ...
The Pareto principle : to what extent does it apply to resource acquisition in stable microbial communities and thereby steer their geno-/ecotype compositions and interactions between their members? Universiteit Gent
The Pareto principle, or 20:80 rule, describes resource distribution in stable communities whereby 20% of community members acquire 80% of a key resource. In this Burning Question, we ask to what extent the Pareto principle applies to the acquisition of limiting resources in stable microbial communities; how it may contribute to our understanding of microbial interactions, microbial community exploration of evolutionary space, and microbial ...
Weaponising microbes for peace Universiteit Gent
There is much human disadvantage and unmet need in the world, including deficits in basic resources and services considered to be human rights, such as drinking water, sanitation and hygiene, healthy nutrition, access to basic healthcare, and a clean environment. Furthermore, there are substantive asymmetries in the distribution of key resources among peoples. These deficits and asymmetries can lead to local and regional crises among peoples ...
Toward circular economy : the impact of policy instruments on circular economy innovation for European small medium enterprises Universiteit Gent
The transition from current linear economy toward a circular economy (CE) needs the adoption and diffusion of circular economy innovation (CEI). However, the rate and direction of CEI influenced by policy instruments are still not well understood. This paper explores the roles of demand-pull and technology-push policy instruments in shaping CEI in Europe. The different impacts on the adoption across different sectors and the specific effects on ...
Analysis of non-axenic biomasses for self-healing concrete Universiteit Gent
As an alternative to the usage of axenic bacteria to achieve microbially induced calcium carbonate precipitation (MICP), this study evaluates the usage of two non-axenic biomasses as self-healing agents. A fungi-based consortium (Yeast) and heterotrophic nitrifiers (HTN) were harvested from the incubation of agricultural side streams. The characteristics of the two biomasses were identified through flow cytometry, total suspended solids and ...
Multiple intertwined crises facing humanity necessitate a European Environmental Research Organization Universiteit Gent
Performance of second-generation microbial protein used as aquaculture feed in relation to planetary boundaries Universiteit Gent
Direct nitrogen stripping and upcycling from anaerobic digestate during conversion of cheese whey into single cell protein Universiteit Gent
The environmental impact of the dairy industry is heavily influenced by the overproduction of nitrogen- and carbon-rich effluents. The present study proposes an innovative process to recover waste contaminated nitrogen from anaerobic digestate while treating excess cheese whey (CW) and producing high-quality, clean single cell protein (SCP). By relying on direct aeration stripping techniques, employing an airflow subsequently used in the aerobic ...
