Effect of catalase on hydrogen peroxide penetration into Pseudomonas aeruginosa biofilms

Article Abstract:

Results indicate that catalase protects Pseudomonas aeruginosa biofilms by not allowing hydrogen peroxide penetrate full into the aggregated bacteria.

Factors affecting catalase expression in Pseudomonas aeruginosa biofilms and planktonic cells

Article Abstract:

Iron seems to be a requirement for the production of catalase in Pseudomonas aeruginosa biofilms but not in planktonic cells. When bacteria are grown in culture media they are planktonic, but research shows the most bacteria prefer to grow in biofilms.

Protective role of catalase in Pseudomonas aeruginosa biofilm resistance to hydrogen peroxide

Article Abstract:

Research was conducted to determine the role of catalase enzymes in protecting bacterial biofilms against hydrogen peroxide biocide. Results indicate besides the protective action of the catalases, other mechanisms also appear to influence resistance of biofilms to hydrogen peroxide.
