Abstract:
... During solid-state fermentation, aerial hyphae occupy the interparticle spaces, binding adjacent particles and decreasing the efficiency of mass and heat transfer within the bioreactor bed. The present work explores two questions related to this phenomenon: (i) what determines the direction of growth of vegetative aerial hyphae and (ii) what makes them stop growing? We developed a discrete mathema ...

Abstract:
... Source-separated urine is of interest for nutrient recovery. Most nitrogen recovery technologies rely on ammonia (NH3) as input, which requires ureolysis. As urease positive bacteria are widespread, source-separated urine is unstable, not only leading to NH3 release but also loss, odor nuisance, and downstream scaling. Hence, ureolysis ideally occurs in a closed controlled environment close to the ...
