  1. 1. 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.

  2. 2. Understanding poverty-environment interactions : the political ecology of smallholder tobacco production in Marondera District, Eastern Zimbabwe

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Richwell Tryson Musoma; [2016]
    Keywords : poverty-environment interactions; environmental degradation; tobacco; political ecology; sustainable livelihoods;

    Abstract : Poverty and environmental degradation are among the severest challenges faced in the developing countries. Since the rise of the sustainable development paradigm, poverty came to be identified as one of the major causes of environmental degradation. READ MORE

  3. 3. Over-expression, purification and characterization of a β-mannanase BoMan26B from Bacteroides ovatus

    University essay from Lunds universitet/Kemiska institutionen

    Author : Leila Allahgholi; [2016]
    Keywords : processivity; Enzyme kinetics; β-mannanase BoMan26B; biochemistry; biokemi; Chemistry;

    Abstract : Hemicelluloses account for 25-30% of total wood dry weight. Mannan-based polysaccharides are the major component of softwood hemicelluloses. They are characterized by their β-1,4-glycosidic linked backbone composed of mannose or a combination of mannose and glucose residues. The backbone can be substituted by α-1,6-linked galactose residues. READ MORE

  4. 4. Watershed-based payment for ecosystem services in Liberia: Examining prospects and challenges for implementation in the St. Paul River Basin

    University essay from Lunds universitet/Internationella miljöinstitutet

    Author : Phillip Innis; [2016]
    Keywords : payments for watershed services; ecosystem services; sustainable land-use practices; Social Sciences;

    Abstract : Payments for watershed services (PWS) are intended to provide incentives to land users to adopt sustainable land management practices. They are also increasingly viewed as having positive impacts on the livelihood of local communities around protected areas. The St. Paul River, located in the St. READ MORE

  5. 5. Investigation of the orientation of Myriococcum thermophilum Cellobiose Dehydrogenase (MtCDH) immobilized on graphite electrodes

    University essay from Lunds universitet/Kemiska institutionen

    Author : Ardian Salihu; [2016]
    Keywords : biosensor; amperometric flow injection analysis; cellobiose dehydrogenase; MtCDH; Myriococcum thermophilum; direct electron transfer; mediated electron transfer; analytical chemistry; analytisk kemi; Chemistry;

    Abstract : Orientation of Myriococcum thermophilum Cellobiose Dehydrogenase (MtCDH) immobilized on spectroscopic graphite electrodes has been investigated electrochemically through flow injection analysis in order to obtain more information about the DET efficiency of this enzyme. The effect of applied potential and the long term stability of the modified electrodes were determined, as well as the bioelectrocatalytic current response with lactose as substrate was investigated by amperometric flow injection measurements in both direct and mediated electron transfer mode, with 1,4-benzoquinone as mediator.
