  1. 1. Mould on building materials - A calorimetric study of fungal activity as a function of environmental factors

    Författare :Yujing Li; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materiallära; byggnadsteknik; building construction; fungal activity; temperature; relative humidity; building; image analysis; indoor environment; wood; materialteknik; material technology; mould; calorimetry; isothermal calorimeter;

    Sammanfattning : Mould problems in buildings have become a growing concern during the past decades. The growth of mould fungi indoors deteriorates air quality, influences human health and causes economical losses. Preventing mould growth from occurring is a more cost effective option than cleaning and renovation of buildings with mould problems. LÄS MER

  3. 2. Calorimetric methods for the study of fungi on building materials

    Författare :Yujing Li; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fungal growth; fungal activity; ergosterol; humidity; temperature; calorespirometry; oxygen; mätmetoder; röta; svamp; byggmaterial; påväxt; kalorimetri; microcalorimetry; isothermal calorimetry; Fungi; building materials; mould; Serpula lacrymans; rot fungi;

    Sammanfattning : The aim of this project is to study the fungal growth habits on building materials as a function of humidity, temperature and other environmental parameters. The method of calorimetry is used as a way to quantify fungal activity on building materials. LÄS MER

  4. 3. Biosynthetic and synthetic studies of the fungal metabolite galiellalactone

    Författare :Martin H Johansson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biotechnology; Bioteknik; Organisk kemi; Organic chemistry; enzyme; mycelium; intramolecular Diels-Alder reaction; Diels-Alderase; asymmetric synthesis; biosynthesis; total synthesis; STAT3 inhibition; galiellalactone; fungal metabolite;

    Sammanfattning : Galiellalactone is a fungal metabolite found in the basidiomycetes Galiella rufa and the unidentified strain A111-95. It has been shown to possess promising activities as an inhibitor of the IL-6 mediated STAT3 signaling in HepG2 cells. LÄS MER

  5. 4. Bacterial and fungal growth in soil: The effect of temperature and substrate addition

    Författare :Stephanie Reischke; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bacterial growth; Fungal growth; Respiration; Carbon loading; Glucose mineralisation; Temperature adaptation; Temperature sensitivity; Temperature dependence;

    Sammanfattning : Bacteria and fungi are the main agents in decomposition of soil organic matter. Their activity is determined by the availability and quality of substrate, especially its content of carbon, but also nitrogen and phosphorus. Other environmental factors, which affect the activity of the microbial community in soil, are temperature, moisture and pH. LÄS MER

  7. 5. Terpenoid Conidiation Factors in Penicillium cyclopium

    Författare :Yanhong He; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; acetals; hydrolysis; Biotechnology; Bioteknik; total synthesis; analogues; synthesis; conidiogenone; conidiogenol; terpenoid; Penicillium cyclopium; conidiation inducing activity; Natural product; fungal metabolites;

    Sammanfattning : Filamentous fungi produce asexual dispersive spores (conidia), when conditions are not suitable for apical extension growth. Conidiation (the process by which conidia produced) in genus Penicillium has attracted considerable interest because of its wide usage in different areas. LÄS MER
