  • 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...

  • Transformation of Phenanthrene by Mycobacterium sp. ELW1 and the Formation of Toxic Metabolites

    Creator:
    Schrlau, Jill E.
    Abstract:
    The ability of Mycobacterium sp. ELW1, a novel microbe capable of alkene oxidation, to co-metabolize phenanthrene (PHE) was studied. ELW1 was able to completely co-metabolize PHE, at different concentrations below its water solubility limit, in an aqueous environment. The alkene monooxygenases in ELW1, used to initiate oxidation of PHE, were...
