Anaerobic microbial hydrolysis and fermentation of food waste for volatile fatty acid production
Nzeteu, Corine (2016-04-28)Landfill, incineration, compositing and anaerobic digestion (AD) are the principal food-waste (FW) treatment methods used in the European Union. Because of the EU landfill directive and waste-management policies on organic ... -
Assessing the impact of wastewater treatment plant effluent on the norovirus contamination of shellfisheries
Flannery, John (2014)Norovirus (NoV) is the most common cause of viral gastroenteritis in the developed world. The discharge of Wastewater treatment plant (WWTP) effluent to the marine environment has implications for the virus quality of ... -
Characterization of a novel antimicrobial agent inspired by peroxidase-catalyzed systems
Tonoyan, Lilit (2017-09-29)The phenomenon of antibiotic resistance is expanding and the threat regarding our future ability to combat infection is increasing. Thus, key challenges for society and for researchers are to address microbial drug resistance ... -
A functional approach to characterising the microbial communities underpinning low temperature anaerobic digestion
Gunnigle, Eoin (2013-03-06)Low-temperature anaerobic digestion (LTAD) presents a sustainable, cost-efficient technology for the treatment of a vast array of wastewater streams. However, this microbially-mediated process requires further understanding ... -
Hydrolysis, methanogenesis and bioprocess performance during low-temperature anaerobic digestion of dilute wastewater
Keating, Ciara (2015-04-28)Anaerobic digestion (AD) technologies represent sustainable and appropriate systems for the treatment of organic wastewaters. Lettinga et al (1987) stated, "A satisfactory application to raw domestic sewage would represent ... -
Investigation of faecal pollution sources and bacterial transfer hydrodynamics in rural catchments
Murphy, Sinéad (2015-03-13)Faecal bacteria from point and diffuse source pollution can impact water which poses a serious public health and environmental threat. Faecal pollution contains nutrients such as phosphorus and nitrogen and when in excess ... -
Investigation of microbial community structure and function underpinning grass and food waste anaerobic digestion
Joyce, Aoife (2016-08-18)Anaerobic digestion (AD) of feedstocks, such as grass and food waste, presents a sustainable and cost efficient technology for the generation of bioenergy and value added products. However, to fully optimize the process, ... -
Linking microbial community structure and function to process performance and reactor configuration during high-rate low-temperature anaerobic treatment of dairy wastewater
McAteer, Paul Gerard (NUI Galway, 2018-09-14)Anaerobic digestion is a sustainable and attractive option for the treatment of wastewaters. It allows the recovery of energy from waste - in the form of biogas - and is more cost-efficient than aerobic biological treatments. ... -
Low-temperature anaerobic digestion as a core technology for the sustainable treatment of municipal wastewater
Hughes, Dermot (2013-11-29)The currently applied paradigm for municipal wastewater treatment in the European Union does not meet basic sustainability criteria. Indeed, it runs counter to the stated goals of recent European Council policies regarding ... -
Molecular characterisation of norovirus contamination in wastewater and oysters
Rajko-Nenow, Paulina (2014-05-16)Bivalve molluscan shellfish (BMS), such as oysters, when grown in waters impacted by human wastewater may bioaccumulate human enteric viruses such as Norovirus (NoV). NoV is the leading agent of foodborne viral gastroenteritis ... -
Nematode response to nitrogen and phosphorus in grasslands, assessed by microscopy and molecular methods
Chen, Xiaoyun (2012-09-19)Although nematode community analysis is considered to be a useful environmental indicator, a major impediment to its wider adoption is the need for detailed morphological identification. Molecular techniques offer an ... -
Potential and optimisation of agriculture-based anaerobic digestion for environmental mitigation of agriculture-associated pollution
Nolan, Stephen (NUI Galway, 2020-12-10)The current work has taken a holistic approach to understanding the potential for mitigation of pollution from agriculture using anaerobic digestion (AD), with a particular focus on reduction of pathogen load to the ... -
A quantitative and qualitative analysis of microbial community development during low-temperature anaerobic digestion of dairy wastewater
Bialek, Katarzyna (2012-06-25)The objective of this thesis was to link microbial community structure, population dynamics and microbial activity with performance of two different bioreactor configurations during low-temperature anaerobic digestion of ...
