  2. 6. EVALUATION OF BIOLOGICAL STRATEGIES TO ENHANCE HYDROLYSIS DURING ANAEROBIC DIGESTION OF COMPLEX WASTE

    Author : Dores Cirne; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Miljöteknik; kontroll av utsläpp; Biotechnology; bioaugmentation; enzyme addition; Environmental technology; pollution control; FISH; cellulose; inhibition; lipids; Clostridium lundense; hydrolysis; complex substrate; Anaerobic digestion; renewable energy; Bioteknik; LCFA;

    Abstract : Anaerobic digestion (AD) offers considerable potential in the production of energy from renewable sources, and is being increasingly recognised as a sustainable technology for the treatment of waste. The production of energy from waste such as municipal solid waste (MSW), lipid-rich waste, and agricultural biomass and waste may play an important role in the production of renewable energy given the huge amounts of these types of waste generated annually.

  4. 7. Enhanced Enzymatic Hydrolysis of Lignocellulose in Bioethanol Production Substrate Interactions with Surfactants and Polymers

    Author : Johan Börjesson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; enzymologi; Penicillium brasilianum; SSF; Ethanol; Proteins; enzymology; Proteiner; Protease; Adsorption; PEG; Surfactant; Hydrolysis; Lignocellulose; Cellulase; Hypocrea jecorina; Trichoderma reesei; Cellulose;

    Abstract : Ethanol produced from cellulose is a promising future alternative fuel. The production process has three main steps: (i) pretreatment of raw material to increase degradability; (ii) enzymatic hydrolysis of cellulose to produce glucose; (iii) fermentation of glucose into bioethanol.

  5. 8. Modeling of enzyme kinetics on polymeric substrates by simulation : Enzymatic hydrolysis of cellulose

    Author : Veljo Sild; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Biopolymers are an essential constituent of living matter. To develop new products and processes based on enzyme production and modification and hydrolysis of biopolymers, enzymes with well understood mechanism are required. It is impossible to derive a universal analytical model for every particular enzyme/polymer system. READ MORE

  6. 9. Zygomycetes and cellulose residuals : hydrolysis, cultivation and applications

    Author : Patrik Lennartsson; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; zygomycetes; fungi; lignocelluloses; ethanol; fish feed; animal feed; dimorphism; airlift; pretreatment; Biotechnology; Resursåtervinning; Resource Recovery;

    Abstract : Zygomycetes is a class of fungi living worldwide as saprobes, as part of mycorrhizae, and as parasites. Humans have used some zygomycetes for centuries in the production of traditional foods, e.g. Indonesian tempe. READ MORE

  7. 10. Biodegradable Surfactants Containing Hydrolyzable Bonds

    Author : Maria Stjerndahl; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; amide; alkaline hydrolysis; cleavable surfactant; carbonate; ester; biodegradation; CMC; enzymatic hydrolysis; mixed micelle;

    Abstract : Surfactants with built-in weak bonds, so-called cleavable surfactants, are interesting candidates in the search for more environmentally friendly alternatives to traditional surfactants. The objective of this thesis was to perform a systematic study in which cleavable surfactants with different hydrolyzable bonds were compared with regard to physicochemical properties, and chemical and biological stability.
