A functional approach to uncover the low-temperature adaptation strategies of the archaeon methanosarcina barkeri
Gunnigle, E.; McCay, P.; Fuszard, M.; Botting, C. H.; Abram, F.; O'Flaherty, V. (American Society for Microbiology, 2013-05-03)Low-temperature anaerobic digestion (LTAD) technology is underpinned by a diverse microbial community. The methanogenic archaea represent a key functional group in these consortia, undertaking CO2 reduction as well as ... -
A metaproteomic approach gives functional insights into anaerobic digestion
Abram, F.; Enright, A.-M.; O’Reilly, J.; Botting, C.H.; Collins, G.; O’Flaherty, V. (Wiley-Blackwell, 2011-04-27)Aims: The objective of this work was to provide functional evidence of key metabolic pathways important for anaerobic digestion processes through the identification of highly expressed proteins in a mixed anaerobic microbial ... -
Characterization of environmentally persistent escherichia coli isolates leached from an irish soil
Brennan, F. P.; Abram, F.; Chinalia, F. A.; Richards, K. G.; O'Flaherty, V. (American Society for Microbiology, 2010-02-12)Soils are typically considered to be suboptimal environments for enteric organisms, but there is increasing evidence that Escherichia coli populations can become resident in soil under favorable conditions. Previous work ... -
Identification of components of the sigma b regulon in listeria monocytogenes that contribute to acid and salt tolerance
Abram, F.; Starr, E.; Karatzas, K. A. G.; Matlawska-Wasowska, K.; Boyd, A.; Wiedmann, M.; Boor, K. J.; Connally, D.; O'Byrne, C. P. (American Society for Microbiology, 2008-09-19)Sigma B (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 ... -
Proteomic analyses of a listeria monocytogenes mutant lacking b identify new components of the b regulon and highlight a role for b in the utilization of glycerol
Abram, F.; Su, W.-L.; Wiedmann, M.; Boor, K. J.; Coote, P.; Botting, C.; Karatzas, K. A. G.; O'Byrne, C. P. (American Society for Microbiology, 2007-12-07)In Listeria monocytogenes the alternative sigma factor sigma(B) plays important roles in both virulence and stress tolerance. In this study a proteomic approach was used to define components of the (sigma(B) regulon in L. ...
