Characterisation of a modified rotating disk reactor for the cultivation of Staphylococcus epidermidis biofilm

Cotter, John J. ; O'Gara, James P. ; Stewart, Philip S. ; Pitts, Betsey ; Casey, Eoin (Wiley, 2010-12)

Aims: The purpose of this study was to develop a system that would allow biofilms to be cultivated under strictly defined conditions in terms of dissolved oxygen, fluid shear and to assess whether the method was suitable ...
Oxygen-mediated regulation of biofilm development is controlled by the alternative sigma factor sigma(B) in Staphylococcus epidermidis

Cotter, John J. ; O'Gara, James P. ; Mack, Dietrich ; Casey, Eoin (ASM, 2009-01)

Using a modified rotating-disk reactor to sparge oxygen to Staphylococcus epidermidis cultures, we found that oxygen negatively regulates biofilm development by influencing the activity of {sigma}B. Under anaerobic conditions, ...
Rapid depletion of dissolved oxygen in 96 well microtitre plate Staphylococcus epidermidis biofilm assays promotes biofilm development and is influenced by inoculum cell concentration

Cotter, John J. ; O'Gara, James P. ; Casey, Eoin (Wiley, 2009-08-01)

Biofilm-related research using 96-well microtiter plates involves static incubation of plates indiscriminate of environmental conditions, making oxygen availability an important variable which has not been considered to ...
