Persister cells in a biofilm treated with a biocide
Simões, Lúcia C.; Lemos, Madalena; Pereira, Ana M.; Abreu, Ana C.; Saavedra, Maria J.; Simões, M.This study investigated the physiology and behaviour following treatment with ortho-phthalaldehyde (OPA), of Pseudomonas fluorescens in both the planktonic and sessile states. Steady-state biofilms and planktonic cells were collected from a bioreactor and their extracellular polymeric substances (EPS) were extracted using a method that did not destroy the cells. Cell structure and physiology after EPS extractio...
The effects of glutaraldehyde on the control of single and dual biofilms of Bac...
Simões, Lúcia C.; Lemos, Madalena; Araújo, Paula; Pereira, Ana M.; Simões, M.Glutaraldehyde (GLUT) was evaluated for control of single and dual species biofilms of Bacillus cereus and Pseudomonas fluorescens on stainless steel surfaces using a chemostat system. The biofilms were characterized in terms of mass, cell density, total and matrix proteins and polysaccharides. The control action of GLUT was assessed in terms of inactivation and removal of biofilm. Post-biocide action was chara...
