  1. 1. Robust Encapsulation of Yeast for Bioethanol Production

    Master-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

    Författare :Sainath Namthabad; Ramesh Chinta; [2014]
    Nyckelord :Microencapsulation; Cell immobilization; Entrapment; Biomineralization; Genipin; Bioethanol; Lignocellulosic hydrolyzates;

    Sammanfattning : 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.

  3. 2. Teknisk utvärdering av en ny miljövänlig förbehandlingsmetod av biomassaavfall med utspädd salpetersyra

    Magister-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

    Författare :Li Zhi; Oliver Murgårdh; [2012]
    Nyckelord :lignin; cellulosic ethanol; sweet liquor; pre-treatment; dilute nitric acid pulping; SSF; SHF; cellic ctec2; yeast; NABC; bio-refining;

    Sammanfattning : Bio-refining of renewable resources such as waste biomass into value added products has increased rapidly over the last decades. The aim is to find new environmentally friendly yet economically feasible ways of replacing current utilization of non renewable resources. LÄS MER

  4. 3. Integrated storage and pretreatment of wheat straw with different fungi : impact on ethanol production and storage microflora

    Master-uppsats, SLU/Dept. of Microbiology

    Författare :Harikrishnan Anjaly Sukumaran Nair; [2011]
    Nyckelord :Biofuel; wet storage; Biocontrol; Dilute acid pretreatment; Simultaneous; Pichia anomala; Pichia stipitis; Anthracophyllum discolor;

    Sammanfattning : Production of ethanol using cellulosic material as feedstock is crucial for sustainable fuel ethanol production.However a production process based on cellulosic biomass involves several energy and cost intensive steps like storage of biomass, pretreatment, hydrolysis and fermentation, where pretreatment is the energy intensive and troublesome step.

  5. 4. Production of ethanol and biomass from orange peel waste by Mucor indicus

    Magister-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

    Författare :Päivi Ylitervo; [2009]
    Nyckelord :orange peel waste; mucor indicus; ethanol; chitosan; acid hydrolysis; enzymatic hydrolysis;

    Sammanfattning : For the citrus processing industry the disposal of fresh peels has become a major concern for manyfactories. Orange peels are the major solid by-product. Dried orange peels have a high content ofpectin, cellulose and hemicellulose, which make it suitable as fermentation substrate when hydrolyzed. LÄS MER

  7. 5. Acetosolv delignification of Dichrostachys cinerea biomass for ethanol production

    Magister-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

    Författare :Venkata Prabhakar Soudham; [2009]
    Nyckelord :dichrostachys cinerea; delignification; acetosolv;

    Sammanfattning : The interest in production of fuel ethanol from lignocellulosic materials is continuouslyincreasing due to the urgency of finding non-food substrates for production of bio-fuels.Marabou (Dichrostachys cinerea) is one of the abundant lignocellulosic bio-resources in Cuba,and it could be useful to produce bio-ethanol.
