  1. 1. Filamentous Fungi as a Sustainable Ingredient for Fish Feed

    Författare :Sajjad Karimi; José Teixeira; Högskolan i Borås; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; compound feed; edible filamentous fungi; essential amino acids; low-value substrates; polyunsaturated fatty acids; protein sources; submerged cultivation; thin stillage; Resource Recovery; Resursåtervinning;

    Sammanfattning : Limited feed ingredients hinder aquaculture’s rapid growth. Current unsustainable fish feeding practices use ingredients like fishmeal and soybean meal, which could be directly consumed for as human food. This demands novel alternatives for fish nutrition. LÄS MER

  3. 2. Evaluation of process parameters and treatments of different raw materials for biogas production

    Författare :Malik Badshah; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digestion; biogas; lignocellulosics; inoculum to substrate ratio; feed composition; toxicity; furaldehydes; paper and pulp sludges.;

    Sammanfattning : The anaerobic digestion process results in the production of biogas from a large diversity of organic residues, which can be used as an alternate source of energy generation and for waste management. However, the biogas production technology is not exploited efficiently due to the characteristics of raw materials, poor methane yields, process instability, limited raw materials and lack of knowledge about the process.

  4. 3. Process modeling of semibatch reaction crystallization

    Författare :Marie Ståhl; Åke Rasmuson; Hermann J.M. Kramer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Reaction crystallization; benzoic acid; nucleation; growth; kinetics; growth rate dispersion; Chemical physics; Kemisk fysik;

    Sammanfattning : This thesis aims at increasing the fundamental understanding of reaction crystallization by modeling, simulations and parameter estimation. Benzoic acid is used as the model compound. LÄS MER

  5. 4. Ethanol from Lignocellulose: Physiological Effects of Inhibitors and Fermentation Strategies

    Författare :Mohammad Taherzadeh Esfahani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fermentation; dilute-acid hydrolyzate; ethanol; hydroxymethyl furfural; furfural; acetic acid; lignocellulose; fed-batch; yeast; pantothenate; control; inhibition; HMF;

    Sammanfattning : Fermentative ethanol production from dilute-acid hydrolyzates of wood using the yeast Saccharomyces cerevisiae was investigated. Of known inhibitors in hydrolyzates, acetic acid, furfural and hydroxymethyl furfural (HMF) were found in the highest concentrations (up to about 10 g/l). LÄS MER
