Agricultural anaerobic digestion power plants in Ireland and Germany: policy and practice
Auer, Agathe; Vande Burgt, Nathan H.; Abram, Florence; Barry, Gerald; Fenton, Owen; Markey, Bryan K.; Nolan, Stephen; Richards, Karl; Bolton, Declan; De Waal, Theo; Gordon, Stephen V.; O'Flaherty, Vincent; Whyte, Paul; Zintl, Annetta (Wiley, 2016-08-24)The process of anaerobic digestion (AD) is valued as a carbon-neutral energy source, while simultaneously treating organic waste, making it safer for disposal or use as a fertilizer on agricultural land. The AD process in ... -
Functional responses and adaptation of mesophilic microbial communities to psychrophilic anaerobic digestion
Gunnigle, Eoin; Nielsen, Jeppe L.; Fuszard, Matthew; Botting, Catherine H.; Sheahan, Jerome; O'Flaherty, Vincent; Abram, Florence (Oxford University Press, 2015-10-27)Psychrophilic (<20°C) anaerobic digestion (AD) represents an attractive alternative to mesophilic wastewater treatment. In order to investigate the AD microbiome response to temperature change, with particular emphasis on ... -
Identification of Components of the Sigma B Regulon in Listeria monocytogenes That Contribute to Acid and Salt Tolerance
Boyd, Aoife; Abram, Florence; Karatzas, Kimon-andreas; Matlawska-Wasowska, Ksenia; Connolly, David; O'Byrne, Conor P.; Starr, Emily (American Society for Microbiology, 2008-09)Sigma B is an alternative sigma factor that controls the transcriptional response to stress in Listeria monocytogenes and is also known to play a role in the virulence of this human pathogen. In the present study we ... -
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 ... -
Linking microbial community structure and function during the acidified anaerobic digestion of grass
Joyce, Aoife; Ijaz, Umer Z.; Nzeteu, Corine; Vaughan, Aoife; Shirran, Sally L.; Botting, Catherine H.; Quince, Christopher; O’Flaherty, Vincent; Abram, Florence (Frontiers Media, 2018-03-21)Harvesting valuable bioproducts from various renewable feedstocks is necessary for the critical development of a sustainable bioeconomy. Anaerobic digestion is a well-established technology for the conversion of wastewater ... -
Low-temperature anaerobic digestion is associated with differential methanogenic protein expression
Gunnigle, Eoin; Siggins, Alma; Botting, Catherine H.; Fuszard, Matthew; O'Flaherty, Vincent; Abram, Florence (Oxford University Press, 2015-04-09)Anaerobic digestion (AD) is an attractive wastewater treatment technology, leading to the generation of recoverable biofuel (methane). Most industrial AD applications, carry excessive heating costs, however, as AD reactors ... -
Reproducible, high-yielding, biological caproate production from food waste using a single-phase anaerobic reactor system
Nzeteu, Corine Orline; Trego, Anna Christine; Abram, Florence; O’Flaherty, Vincent (BMC (part of Springer Nature), 2018-03-11)Background: Nowadays, the vast majority of chemicals are either synthesised from fossil fuels or are extracted from agricultural commodities. However, these production approaches are not environmentally and economically ... -
Systems-based approaches to unravel multi-species microbial community functioning
Abram, Florence (Research Network of Computational and Structural Biotechnology, 2014-12-03)Some of the most transformative discoveries promising to enable the resolution of this century's grand societal challenges will most likely arise from environmental science and particularly environmental microbiology ...
