Biological phosphorus removal during high-rate, low-temperature, anaerobic digestion of wastewater
Keating, Ciara; Chin, Jason P.; Hughes, Dermot; Manesiotis, Panagiotis; Cysneiros, Denise; Mahony, Therese; Smith, Cindy J.; McGrath, John W.; O'Flaherty, Vincent (Frontiers Media, 2016-03-03)We report, for the first time, extensive biologically mediated phosphate removal from wastewater during high-rate anaerobic digestion (AD). A hybrid sludge bed/fixed-film (packed pumice stone) reactor was employed for ... -
Concentrations of perfluoroalkyl substances in human milk from Ireland: Implications for adult and nursing infant exposure
Abou-Elwafa Abdallah, Mohamed; Wemken, Nina; Drage, Daniel Simon; Tlustos, Christina; Cellarius, Claire; Cleere, Kathy; Morrison, John J.; Daly, Sean; Coggins, Marie Ann; Harrad, Stuart (Elsevier, 2019-12-20)Concentrations of 10 perfluoroalkyl substances (PFASs) were measured in 16 pools of human milk from Ireland. Only four PFASs were detected (PFOA, PFNA, PFHxS and PFOS), with concentrations dominated by PFOA which was ... -
Development of a Probabilistic Multi-Zone Multi-Source Computational Model for Indoor Air Pollution Exposure Assessment
McGrath, James (2014-02-12)Airborne Particulate Matter (PM) is a major environmental concern because of its known impacts on human health, and since the developed world population spends approximately 89% of its time indoors, PM in the indoor ... -
DNA hybridisation detection on chemically modified electrodes with bioelectrocatalytic amplification of signal
Hajdukiewicz, Joanna (2011-12-22)Electrochemical detection of DNA hybridization is a viable alternative to optical and radio-labelled techniques. The benefits of using biosensors based on electrochemical systems are: high sensitivity, possible development ... -
Genetic and biotechnological development of the pennate marine diatom Phaeodactylum tricornutum for high-value bioproducts and carbon bio-mitigation.
Kaur, Simrat (2014-04-25)Conflicting demands of food over fuel and the mushrooming need for feed and fibre are serious challenges for humankind at a time when we also need to address climate change challenges. Global demands for land based commodities ... -
Impact of trichloroethylene exposure on the microbial diversity and protein expression in anaerobic granular biomass at 37°C and 15°C
Siggins, Alma; Enright, Anne-Marie; Abram, Florence; Botting, Catherine; O'Flaherty, Vincent (Hindawi Publishing Corporation, 2012-09-14)Granular biomass from a laboratory-scale anaerobic bioreactor trial was analysed to identify changes in microbial community structure and function in response to temperature and trichloroethylene (TCE). Two bioreactors ... -
Opportunistic bacteria dominate the soil microbiome response to phenanthrene in a microcosm-based study
Storey, Sean; Ashaari, Mardiana Mohd; Clipson, Nicholas; Doyle, Evelyn; de Menezes, Alexandre B. (Frontiers Media, 2018-11-21)Bioremediation offers a sustainable approach for removal of polycyclic aromatic hydrocarbons (PAHs) from the environment; however, information regarding the microbial communities involved remains limited. In this study, ... -
Physically-based methods for improved high temperature creep performance of 9Cr steels and welds: nano-, micro- and macro-scale studies
Ó Murchú, Cathal (NUI Galway, 2019-09-30)The reduction of emissions from fossil fuel power plants is essential to minimising the environmental impact of power generation and this can be achieved by higher temperature, with more efficient combustion of the fuel. ... -
The role of the natural aquatic environment in the dissemination of extended spectrum beta-lactamase and carbapenemase encoding genes: A scoping review
Hooban, Brigid; Joyce, Aoife; Fitzhenry, Kelly; Chique, Carlos; Morris, Dearbháile (Elsevier, 2020-05-07)The natural aquatic environment is a significant contributor to the development and circulation of clinically significant antibiotic resistance genes (ARGs). The potential for the aquatic environment to act as a reservoir ...
