Salt Adaptations in Listeria monocytogenes

Important information for event attendees and external visitors

coronavirus (COVID-19)In light of the ongoing government restrictions and advice to mitigate risk of COVID-19 transmission, our events have been rescheduled or moved to online delivery.

Our sites remain on a restricted access condition, and only staff who are doing essential site-specific work or tasks are on site. All other colleagues continue to work from home for the time being.

Dr Conor O’Byrne of the National University of Ireland, Galway will give this seminar entitled "Salt Adaptations in Listeria monocytogenes: Role and Regulation of the Stress-Inducible Sigma Factor SigB (σB)at the James Hutton Institute in Aberdeen. It will be broadcast live to the Dundee site.


Conor’s overarching interest is in in molecular responses to stress in bacteria, focusing on Listeria and E.coli.

His current projects are looking at responses to acid in Listeria, especially the glutamate decarboxylase system; role of SigB in sensing and response to blue light in Listeria; stress response in long-term soil-adapted E.coli strains. He has just started a project on biofilm in E.coli (an applied project looking at the possibility of inhibiting biofilm formation on catheters using light).


  • 2002-present: Lecturer National University of Ireland, Galway (Stress responses in Listeria and E.coli).
  • 2000-2002: Lecturer University of Aberdeen (Listeria stress responses).
  • 1998-2000: Postdoc University of Aberdeen (Listeria osmoregulation, with Ian Booth).
  • 1994-1998: Postdoc Unilever Plc (Listeria molecular mechanisms of survival in preserved foods).
  • 1990-1994: PhD University of Dundee (Supercoiling gene expression in Salmonella Typhimurium with Charles Dorman).

The seminar is being hosted by Fiona Brennan.
