1. 11. Enzymatic treatment of wastewater sludge. Sludge solubilisation, improvement of anaerobic digestion and extraction of extracellular polymeric substances

   Författare :Joanna Wawrzynczyk; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pollution control; Environmental technology; sludge treatment; wastewater activated sludge; Proteins; enzymology; Proteiner; enzymologi; cation-binding agents; mass reduction; lectins; extracellular polymeric substances; enzymes; enzymatic activity; anaerobic digestion; biogas; Miljöteknik; kontroll av utsläpp; Biotechnology; Bioteknik;

   Sammanfattning : The processing and disposal of sludge from wastewater treatment plants is an important topic of increasing environmental, ecological, technological, economic and social concern. The large amounts of sludge produced represent an urgent problem today, new treatment methods being very much needed. LÄS MER

3. 12. Mitochondrial differentiation during the early development of the amphibian embryo

   Författare :Lennart Nelson; Barbara Cannon; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Amphibia; Xenopus laevis; Ambystoma mexicanum; mitochondria; differentiation; enzymes; carriers; oxidation; development; Zoophysiology; zoofysiologi;

   Sammanfattning : Mitochondria from Xenopus laevis and Ambystoma mexica- num embryos between fertilization and the beginning of feeding were studied: the former with respect to metabolic behaviour, enzyme pattern and carrier activity, and the latter with respect to morphological parameters.The metabolic behaviour of mitochondria was studied by assessing the rates of oxygen uptake in presence of various substrates.

4. 13. Improvement of Wastewater Sludge Digestion

   Författare :Michael Recktenwald; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anaerobic digestion; biogas; cation-binding agents; enzymes; enzymatic activity; extracellular polymeric substances EPS ; industrial scale trials; methanization; municipal sewage; sludge treatment; wastewater treatment plant;

   Sammanfattning : The reduction of sludge volumes for disposal is a topic of high interest for wastewater treatment plants (WWTP) all over the world. Steadily increasing volumes for disposal create an economic, environmental, legislative and technological challenge. LÄS MER

5. 14. Microbial strategies for deconstruction of bark components

   Författare :Amanda Sörensen Ristinmaa; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; extractives; fungi; microbial communities; polysaccharides; Bark; proteomics; enzymes; bacteria; yeast;

   Sammanfattning : Bark is the outermost part of a tree, and it is a protective layer against external threats such as microorganisms and environmental stressors. Bark consists of various polymers including lignin, cellulose, hemicellulose, and it also contains a large fraction of compounds known as extractives. LÄS MER

7. 15. Recombinant Enzymes in Pyrosequencing Technology

   Författare :Nader Nourizad; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; apyrase; pyrosequencing; pichia pastoris; protein expression; fusion protein; luciferase; DNA template; clone checking; DNA polymerase;

   Sammanfattning : Pyrosequencing is a DNA sequencing method based on thedetection of released pyrophosphate (PPi) during DNA synthesis.In a cascade of enzymatic reactions, visible light isgenerated, which is proportional to the number of nucleotidesincorporated into the DNA template. When dNTP(s) areincorporated into the DNA template, inorganic PPi is released. LÄS MER
