Evaluation of Viable Cells in Pseudomonas aeruginosa Biofilms by Colony Count and Live/Dead Staining
Authors:  Magdalena Pezzoni, Ramón Augusto Pizarro and Cristina Susana Costa, date: 09/20/2020, view: 3428, Q&A: 0
Pseudomonas aeruginosa is a human pathogen capable to form robust biofilms. P. aeruginosa biofilms represent a serious problem because of the adverse effects on human health and industry, from sanitary and economic points of view. ...
Detection of Catalase Activity by Polyacrylamide Gel Electrophoresis (PAGE) in Cell Extracts from Pseudomonas aeruginosa
Authors:  Magdalena Pezzoni, Ramón A. Pizarro and Cristina S. Costa, date: 06/05/2018, view: 7574, Q&A: 0
Bacteria in nature and as pathogens commonly face oxidative stress which causes damage to proteins, lipids and DNA. This damage is produced by the action of reactive oxygen species (ROS) such as hydrogen peroxide (H2O2), ...
