| Abstract: | It was found that seven strains of bacteria can cause corrosion damage to aluminum, its alloys, and zinc. With respect to the studied metals, the most active bacteria were Proteus vulgaris 1212 and Pseudomonas aeruginosa 969. Superoxide anion radicals were demonstrated to play a role in the initiation of corrosive damage to aluminum and zinc, while bacterial exometabolites participate in the later stages of this process. |
