  1. 1. Reducing patulin levels in apple juice by fermentation with Saccharomyces cerevisiae

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

    Author : Oscar Håkansson; [2015]
    Keywords : patulin; Penicillium expansum; apple juice; fermentation; HPLC; Saccharomyces cerevisiae; yeast;

    Abstract : Patulin is a mycotoxin that can be found in many apple products all over the world. It has been well-known for many decades and is nowadays one of the most regulated mycotoxins in food. Today when fruit and vegetables are traded internationally more than ever before, the quality of the goods might fall victim for careless storage during logistics. READ MORE

  2. 2. Odour-mediated behaviour in codling moth, Cydia pomonella : do fermentation odours affect the attraction and oviposition behaviour in codling moth?

    University essay from SLU/Department of Plant Protection Biology

    Author : Lillemor Torstensdotter; [2015]
    Keywords : Cydia pomonella; codling moth; fermentation; apples;

    Abstract : The codling moth, Cydia pomonella is a common pest in apple orchards and can be found worldwide. Feeding by codling moth larvae can cause a substantial decrease in apple yield. Control methods comprise for example the use of pesticides, viruses and pheromones. READ MORE

  3. 3. 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.

  5. 5. 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.
