  1. 1. Trapping social wasps, in apple orchards and vineyards with synthetic volatiles and live yeast cultures in Scania, Scandinavia

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

    Author : Malin Iris Dörre; [2015]
    Keywords : Vespinae; social wasps; lure; semiochemicals; yeast; apple; grapes;

    Abstract : Social wasps (Hymenoptera, Vespinae) foraging for carbohydrate nutrients are a major pest, particularly in berry and fruit orchards. The identification of volatile attractants for social wasp management is accordingly an urgent research challenge. Overripe fruit and fermenting sweet baits are since long known to attract wasps.

  2. 2. Yeast in forage crops and silage aerobic stability at 15 Swedish dairy farms

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Annica Persson; [2015]
    Keywords : fungi; grass crop; ensiling; hygienic quality; losses; jäst; ensilage; lagringsstabilitet; grönmassa;

    Abstract : This study investigates the role of yeast in green crop and its impact on the aerobic stability of silage. Fresh crop was collected from 15 farms in southern and middle parts of Sweden during the summer 2014; samples from the primary harvest was collected from eight farms and samples from the first regrowth harvest was collected from seven farms.

  3. 3. Robust Encapsulation of Yeast for Bioethanol Production

    University essay from Högskolan i Borås/Ingenjörshögskolan (IH)

    Author : Sainath Namthabad; Ramesh Chinta; [2014-01-09]
    Keywords : Microencapsulation; Cell immobilization; Entrapment; Biomineralization; Genipin; Bioethanol; Lignocellulosic hydrolyzates;

    Abstract : In the future the demand for ethanol is expected to increase greatly due to the rising energy requirements in the world. Lignocellulosic materials are a suitable and potentially cheap feedstock for sustainable production of fuel ethanol, since vast quantities of agricultural and forest residues are available in many countries.

  4. 4. Recombinant Schizophyllum commune α-glucuronidase expression and production in the methylotrophic yeast Pichia pastoris

    University essay from Chalmers tekniska högskola/Institutionen för kemi- och bioteknik

    Author : Hormoz Noormohammadian; [2014]
    Keywords : α-glucuronidase; polymeric xylan; glucuronic acid; enzymatic debranching; glycosidic bond; GH115;

    Abstract : The α-glucuronidase of Schizophyllum commune was expressed heterologously in Pichia pastoris. The α-glucuronidase of the wood degrading fungus S. commune belongs to glycoside hydrolase (GH) family 115 andits extracellular activity release D-glucuronic and 4-O-methyl-D-glucuronic acid residues from polymeric xylanbackbone and aldouronic acids.
