    University essay from SLU/Department of Biosystems and Technology (from 130101)

    Author : Simon Hannus; [2017]
    Keywords : Lentinula; Pleurotus; svamp; lignocellulosa; restprodukter; odlingssubstrat; enzymer; substrattillverkning; saprotrof;

    Abstract : Sedan tidigt 2000-tal har den globala produktionen för matsvamp varit under stor tillväxt för att förse en växande marknad, vilket har bidragit till att vednedbrytande matsvampar som ostronskivling och shiitake har börjat få allt större erkännande i västvärlden, där champinjon fortfarande dominerar.
