  2. 1. Battling Bacterial Biofilm - antibiotic regimens targeting Grampositive pathogens in biofilm

    Author : Anna Holmberg; Sektion III; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biofilm; antibiotic susceptibility; prosthetic joint infection; MBEC; Enterococcus faecalis; Enterococcus faecium; Propionibacterium acnes.;

    Abstract : AbstractBacteria in most environments encase themselves in a hydrated matrix of polysaccharide and protein, forming organized communities called biofilms. In the biofilm bacteria are protected against hostile environments. Biofilms are important clinically because of their persistence despite host defence and their recalcitrance to antimicrobials.

  4. 2. Microbial biofilms on peritoneal dialysis catheters

    Author : Maria Pihl; Malmö högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Peritoneal dialysis; Biofilm;

    Abstract : Då njurarna slutar fungera produceras ingen urin, och avfallsprodukterna stannar kvar i blodet. Detta tillstånd kallas uremi (”urin i blodet”) och leder till döden om det inte behandlas. Det finns två artificiella sätt att rena blodet på, hemodialys och peritonealdialys. READ MORE

  5. 3. Experiments on biofilm formation and growth in laminar flows

    Author : Cornelius Wittig; Shervin Bagheri; Thomas Crouzier; Wouter van der Wijngaart; Eleonora Secchi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofilm; streamers; wall shear stress; OCT; Teknisk mekanik; Engineering Mechanics;

    Abstract : The interaction between fluid dynamics and biofilm growth plays a key role in both medical and industrial applications. Biofilms, or bacteria that are embedded in a protective matrix of extracellular polymeric substances, settle on interfaces such as on implanted devices or ship hulls. READ MORE

  6. 4. New Dimensions of Moving Bed Biofilm Carriers : Influence of biofilm thickness and control possibilities

    Author : MARIA PICULELL; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofilm control; biofilm thickness; biological wastewater treatment; carrier; moving bed biofilm reactor; nitrification; nitritation; organic removal; process optimization; scaling; suspended growth;

    Abstract : The moving bed biofilm reactor (MBBR) is a biological wastewater treatment process in which microorganisms grow as biofilms on suspended carriers. Conventionally, MBBRs are mainly designed and optimized based on the carrier surface area, neglecting the dynamic relationship between carrier design, reactor operation and biofilm characteristics, such as biofilm thickness and the composition of the microbial community.

  7. 5. Microbial biofilm communities associated with degradation of sprayed concrete in subsea tunnels

    Author : Sabina Karacic; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; marine environment; subsea tunnels; surface structure; biofilm; steel fibers; metagenomics.; microbially induced deterioration; amplicon sequencing; concrete;

    Abstract : Deterioration of concrete leads to reduced structural strength implying high societal challenge with huge economic impact. In the Oslofjord subsea tunnel, complex microbial biofilm activity together with abiotic attack from saline groundwater are responsible for concrete matrix degradation and steel fiber corrosion.
