Summary
Pseudomonas aeruginosa biofilm in a CDC reactor, one-minute contact at label strength: the NaDCC product reduced it by 8.70 log or more, against 3.82 for peracetic acid and 3.78 for sodium hypochlorite.
Key points
- After one minute at label strength, the NaDCC product reduced Pseudomonas aeruginosa biofilm by 8.70 log or more.
- Peracetic acid reduced the biofilm by 3.82 log and sodium hypochlorite by 3.78 log.
- The authors suggest NaDCC may suit drain disinfection, where biofilm can harbor pathogens.
- Design: lab study using the CDC biofilm reactor, testing three hospital-grade disinfectants at their highest label concentration.
- Funding: all authors work for Kersia, which makes NaDCC, peracetic acid and hypochlorite products; no specific grant.
