  6. 5. Optimization of sterilization method for cultivation of filamentous fungi on lemon waste

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Oliver Conradsson; David Ljungberg; [2023]
    Keywords : Lemon waste; lemon waste; sterilization; autoclavation; fungal cultivation; bubble column bioreactor; fungal biomass Rhizopus delemar;

    Abstract : Consumption of citrus fruits and citrus juice production creates wastes, which could be valorized by using it for cultivating fungi. Before cultivation, the medium needs to be sterilized though autoclavation. Larger volumes used when autoclaving requires longer heating cycles and therefore runs the risk of degrading the medium to a greater extent. READ MORE
