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

    Author : Anna Holmberg; Sektion III; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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.

  5. 3. New Dimensions of Moving Bed Biofilm Carriers : Influence of biofilm thickness and control possibilities

    Author : MARIA PICULELL; Institutionen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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.

  6. 4. Investigation of a Biofilm Reactor Model with Suspended Biomass

    Author : Alma Masic; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; wall attachment; suspended growth; substrate removal; reactor; biofilm; CSTR; mathematical model; MBBR; nitrification; optimization;

    Abstract : Biofilms are compact, sessile microbial communities that attach to surfaces in aqueous environments. In wastewater treatment, they are especially important for removal of phosphorus and nitrogen, which, if released into a receiving water body, can cause severe eutrophication. READ MORE

  7. 5. Adhesion-related interactions of Actinomyces and Streptococcus biofilm bacteria

    Author : Mirva Drobni; Nicklas Strömberg; Karl-Eric Magnusson; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biofilm; Actinomyces; Streptococcus; adhesion; Cariology; Cariologi;

    Abstract : Adhesion of bacteria is a key event in biofilm formation and is mediated by bacterial adhesins recognising host or bacterial partner receptors. In oral biofilm formation, primary Actinomyces and Streptococcus colonizers adhere to salivary pellicle proteins such as proline-rich proteins (PRPs) as well as to mucosal surfaces. READ MORE
