  1. 21. Uncovering novel cell wall chemistries in gram negative bacteria : from development or dedicated peptidoglycan chemometric tools to functional genomics

    Author : Akbar Espaillat; Felipe Cava; Sun Nyunt Wai; Waldemar Vollmer; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bacteria; cell wall; peptidoglycan; peptidoglycan variations; D-amino acids; molekylärbiologi; Molecular Biology;

    Abstract : Bacteria are surrounded by an external cell wall whose main component is a polymeric net-like structure called the peptidoglycan (PG) or murein sacculus. PG plays crucial roles in bacterial physiology (eg morphogenesis, growth fitness and regulation of innate immunity). READ MORE

  2. 22. Optimizing membrane and secretory protein production in Gram-negative bacteria

    Author : Anna Hjelm; Jan-Willem de Gier; Alex Toftgaard Nielsen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; biokemi;

    Abstract : Proteins fulfil a wide variety of essential functions in the cell. Recombinant protein production in the Gram-negative bacterium Escherichia coli (E. coli) facilitates structural and functional studies of proteins and it has been instrumental in biotechnology for the manufacturing of e.g. READ MORE

  3. 23. Bacteriological Hygiene in the Production of Pasteurised Milk

    Author : Åsa Eneroth; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; RAPD; Bacillus cereus; Pseudomonas; Gram-negative; recontamination source; spoilage flora; phychrotrophs; recontamination; dairy hygiene; pasteurised milk; Livsmedelsteknik;

    Abstract : Critical contamination sites and sources for the Gram-negative psychrotrophs (GNP) of the taxa Pseudomonas, Enterobacteriaceae and Aeromonas, and the Gram-positive spore-forming (GPS) species Bacillus cereus, have been traced in the production line of pasteurised milk. Samples of raw and pasteurised milk from different sampling sites along the line were collected. READ MORE

  4. 24. Engineering of staphylococcal surfaces for biotechnological applications

    Author : Henrik Wernérus; KTH; []
    Keywords : affibody; albumin binding protein; Bacterial surface display; cell immobilisation; bioremediation; combinatorial protein engineering; flow cytometry; Gram-positive; metal-binding; staphylococcal protein A; Staphylococcus carnosus; Staphylococcus xylo;

    Abstract : The engineering of bacterial surfaces has in recent yearsattracted a lot of attention with applications in manydifferent areas of bioscience. Here we describe the use of twodifferent surface display systems for the gram-positivebacteria Staphylococcus carnosus and Staphylococcus xylosus invarious biotechnological applications. READ MORE

  5. 25. Efficient Image Retrieval with Statistical Color Descriptors

    Author : Linh Viet Tran; Reiner Lenz; Björn Kruse; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; color properties; images; statistical; content-based image retrieval CBIR ; non-parametric density estimators; image database; Kernel; Gram-Schmidt; geometry-based; Information technology; Informationsteknologi;

    Abstract : Color has been widely used in content-based image retrieval (CBIR) applications. In such applications the color properties of an image are usually characterized by the probability distribution of the colors in the image. READ MORE
