  3. 3. Odlingssubstrat för vednedbrytande matsvampar : hur ostronskivlingens och shiitakens substratpreferenser påverkar vilka organiska restprodukter som lämpas för substrattillverkning

    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. För inhemsk produktion av matsvamp är svenska svampodlare till stor del beroende av import av odlingssubstrat, vilket är märkligt då förutsättningarna för dess tillverkning även bör finnas i Sverige.
