  • The effect of silver ions and nanoparticles on biofilms and planktonic cultures of Nitrosomonas europaea

    Creator:
    Giska, Jonathan R.
    Abstract:
    Due to the effective antimicrobial properties of silver nanoparticles they represent a significant proportion of all consumer-­‐related nanomaterials. The introduction of silver nanoparticles from these products into domestic and industrial wastewater streams poses potential complications for biological treatment systems. A critical component of biological treatment that is extremely sensitive to...

  • Inhibition of the ammonia oxidizing bacteria Nitrosomonas europaea by the emerging contaminant triclosan

    Creator:
    Hughes, Jamie L.
    Abstract:
    Identifying the inhibition of ammonia oxidizing bacteria (AOB) by emerging organic contaminants is crucial due to the importance of AOB in wastewater treatment, the widespread use of antibacterial agents such as triclosan (TCS) in consumer products, and the sensitivity of N. europaea to inhibitors. Triclosan inhibition of nitrification by AOB...

  • Effects of silver ions and nanoparticles on suspended cells and biofilms of Nitrosomonas europaea

    Creator:
    Barker, Leila Kelly
    Abstract:
    Silver nanoparticles are increasingly being incorporated into consumer products due to their broad-spectrum antimicrobial properties. The resulting influx of silver nanoparticles into wastewater may pose a threat to bacteria involved in biological wastewater treatment. Ammonia-oxidizing bacteria, which convert ammonia to nitrite in the first step of nitrification, are highly sensitive...
