Most P. aeruginosa produce bacteriocins called pyocins, typically several of them. (sciencedaily.com)
These bacteria compete with pathogenic bacteria for nutrients, as well as produce inhibitory substances such as bacteriocins and organic acids that can kill or limit the growth of bacterial pathogens (9). (foodasmedicine.ca)
The model organism Pseudomonas aeruginosa is famous for multidrug resistance, but compounds called bacteriocins may be able to outflank it. (sciencedaily.com)
