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

   Author : Yujing Li; Avdelningen för Byggnadsmaterial; []
   Keywords : 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;

   Abstract : 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. READ MORE

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

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

   Abstract : 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. READ MORE

5. 3. Superabsorbent Polymers from the Cell Wall of Zygomycetes Fungi

   Author : Akram Zamani; Högskolan i Borås; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; chitosan; cell wall; chitin; polyphosphates; dilute sulfuric acid; zygomycetes fungi;

   Abstract : The present thesis presents new renewable, antimicrobial and biodegradable superabsorbent polymers (SAPs), produced from the cell wall of zygomycetes fungi. The cell wall was characterized and chitosan, being one of the most important ingredients, was extracted, purified, and converted to SAP for use in disposable personal care products designed for absorption of different body fluids.

6. 4. Factors Affecting Rates of Change in Soil Bacterial Communities

   Author : Marie Pettersson; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; Plant ecology; Växtekologi; bacteriology; Microbiology; DGGE; PLFA; TdR-incorporation; function; structure; tolerance; adaptation; pH; soil bacterial community; temperature;

   Abstract : The soil bacterial community is under the constant influence of its environment. Changing any of the factors affecting the bacterial community will induce a selection pressure which, with time, will change the community. In this work the effect of changing the temperature or pH on the soil bacterial community was studied. READ MORE

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

   Author : Yujing Li; Avdelningen för Byggnadsmaterial; []
   Keywords : 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;

   Abstract : 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. READ MORE
