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 ...
