H2O2 | Pseudomonas aeruginosa | essential for optimal resistance to H2O2. KatB was not produced during the normal growth cycle. Catalase activity is greater in nonmucoid than in mucoid, alginate-producing organisms. When exposed to hydrogen peroxide and, to a greater extent, paraquat, total catalase activity was elevated 7fold to 16fold, respectively | O2 + H2O | - |
