  1. 6. Hygiene Aspects of Greywater and Greywater Reuse

    Författare :Jakob Ottosson; KTH; []
    Nyckelord :greywater; greywater reuse; greywater treatment; microbial risk assessment; groundwater recharge; irrigation; recreational water; faecal contamination; indicator bacteria; index organisms; faecal sterols; bacteriophages; enteric pathogens; rotavirus; ;

    Sammanfattning : Greywater is domestic household wastewater without inputfrom the toilet, i.e. wastewater from sinks, the shower,washing machine and dishwasher in a home. Source separation ofgreywater can be a strategy to enhance recirculation of plantnutrients and/or improve water use. LÄS MER

  3. 7. The external mycorrhizal mycelium - growth and interactions with saprophytic microorganisms

    Författare :Pål Axel Olsson; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bacteriology; Microbiology; Fatty acids; Mycorrhiza; Bacteria; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : The interactions between external mycorrhizal mycelia and saprophytic microorganisms were studied in experiments with growth chambers specially designed to enable the mycelia to develop in root-free soil compartments. The growth of the mycorrhizal mycelia was estimated by use of biochemical signature compounds. LÄS MER

  4. 8. Comparative analysis of pathogen occurrence in wastewater : management strategies for barrier function and microbial control

    Författare :Jakob Ottoson; Bengt Hultman; Roland Schertenleib; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bacteria; parasites; treatment; Water engineering; Vattenteknik;

    Sammanfattning : This project was initiated to fill knowledge gaps on the occurrence of pathogens in different streams of wastewater, e.g. greywater and domestic wastewater. LÄS MER

  5. 9. On the development of low level resistance in gram-positive and gram-negative bacteria after antibiotic exposure

    Författare :Gunilla Rådberg; Signe Ringertz; Östergötlands Läns Landsting; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Resistance has been found to develop and spread via several mechanisms against virtually all clinically available antimicrobial agents. Increasing use of antibiotics has been shown to correlate to increasing incidence of bacterial resistance. LÄS MER

  7. 10. Enterococcal distribution and responses toenvironmental waters

    Författare :Ebraheem M. Elmarghani; Jana Jass; Per-Erik Olsson; Nikolai Scherbak; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Enviromental Science; Miljövetenskap; Mikrobiologi; Microbiology;

    Sammanfattning : The release of antibiotics and pharmaceuticals into environmental waters contribute to the increasing risk of antibiotic resistant bacteria. The spread of antibiotic resistant bacteria in the environment increases the health risks to the community. Enterococci are fecal indicator bacteria (FIB) in aquatic environments for determining water quality. LÄS MER
