- Applications
  - Application Description
    
    Microbiology Applications: Cetrimide is often used in selective media for Pseudomonas aeruginosa. Enterococcus faecalis can grow as a biofilm in the root canals of teeth. Using a MBEC-high-throughput device to study these types of biofilms, authors found that an irrigating solution of Cetrimide was able to eradicate the bacteria (Arias-Moliz et al, 2010).
    
    Plant Biology Applications: Cetrimide is an active ingredient in Cetavlon, a detergent and antiseptic used in plant/tree tissue culture prior to surface sterilization. A commercially important tropical fruit tree in India is the blackplum (Syzygium cuminii L ). Seeds were treated with 1% (v/v) Cetavlon prior to surface sterilization (Yadav, 1989). Newly developed leaves from apical portions of Guava plants were treated with 1% (v/v) Cetrimide prior to surface sterilization (Amin, 1986).
