  2. 1. Development of biocomposites from lactic acid thermoset resins and cellulose fibre reinforcements

    Author : Fatimat Oluwatoyin Bakare; Minna Hakkarinen; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lactic acid; thermoset resin; renewable resources; natural fibre; regenerated cellulose fibre; composite; Resursåtervinning; Resource Recovery;

    Abstract : Synthesis of polymers from renewable origin has been reported by many authors and it has been found out that it has enormous potential and can serve as alternative to conventional thermoplastics and thermosets in many applications. The use of these renewable resources will provide sustainable platforms to substitute fossil fuel-based materials. READ MORE

  4. 2. Process development for platform chemical production from agricultural and forestry residues

    Author : David Nickel; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Biorefinery; pretreatment; lignocellulose; multi-feed SSCF; preadaptation; multi-scale variability analysis; platform chemicals; lactic acid; logging residues; mixed feedstocks; ethanol;

    Abstract : As part of a bio-based economy, biorefineries are envisaged to sustainably produce platform chemicals via biochemical conversion of agricultural and forestry residues. However, supply risks, the recalcitrance of lignocellulosic biomass, and inhibitor formation during pre­treatment impair the economic feasibility of such biorefineries. READ MORE

  5. 3. In silico analysis of microbial communities through constraint-based metabolic modelling

    Author : Parizad Babaei; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fermented food production; metagenomics; genome-scale metabolic model; community modelling; malnourishment; Microbial community; systems biology; lactic acid bacteria; gut microbiota; uniform randomised sampling;

    Abstract : Microbial communities are involved in many vital biological processes from elemental cycles to sustaining human health. The bacterial assemblages are remarkably under-studied as they are reluctant to grow in the laboratory conditions. READ MORE

  6. 4. Lactic acid production: extractive fermentation in aqueous two-phase systems

    Author : Jordi Planes; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gel excludion chromatography; polyethylenimine; ethylene oxide propylene oxide; phase forming polymers; aqueous two-phase systems; extractive fermentation; Lactococcus; Lactobacillus; Mikrobiologi; bakteriologi; virologi; mykologi; bacteriology; virology; mycology; Microbiology;

    Abstract : There is an increased interest in the microbial production of lactic acid as a raw material for the synthesis of lactic acid polymers as biodegradable plastics. However, two factors limit the economical competitiveness of lactic acid production by microorganisms: lactic acid inhibition, which decreases both fermentation rate and the maximum lactic acid concentration, and the efficiency in the recovery of lactic acid.

  7. 5. Hereditary ichthyosis : Causes, Skin Manifestations, Treatments and Quality of Life

    Author : Agneta Gånemo; Åke Svensson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dermatology and venereology; Ichthyosis; congenital ichthyosis; genodermatoses; skin disease; quality of life; topical treatment; lactic acid; propylene glycol; Dermatologi och venerologi; Dermatology and venerology; Dermatologi och venerologi; Dermatology and Venerology; dermatologi och venereologi;

    Abstract : Hereditary ichthyosis is a collective name for many dry and scaly skin disorders ranging in frequency from common to very rare. The main groups are autosomal recessive lamellar ichthyosis, autosomal dominant epidermolytic hyperkeratosis and ichthyosis vulgaris, and x-linked recessive ichthyosis. READ MORE
