Rapid bactericidal effect of low pH againstPseudomonas aeruginosa

  • Original Papers
  • Published:
Journal of Industrial Microbiology

Summary

Solutions with a pH of 3 or lower had a bactericidal effect within 60 s againstPseudomonas aeruginosa and other Gram-negative eubacteria in an assay based on the A.O.A.C. germicidal and detergent sanitizer assay. This effect was not observed on the Gram-positive eubacteria and yeasts examined. Acidification of disinfectants to improve their activity against Gram-negative eubacteria is a common practice. It is shown here that low pH itself can have a rapid bactericidal activity.
