EVALUATlON OF THE LETHEEN BROTH NEUTRAlIZATION ACTlON PREPARED WITH UMPURIFVED SOJA LECITIN ON AMMONIUM QUATERNARV AND PHENOL DISINFECTANTS
Abstract
The utilization of substances that might neutralize antimicrobial chemical agents action has been recomended to evaluate disinfectantes action potential. For phenolic and quaternary ammonium disinfectantes
has been suggested culture media (agar Letheen or Letheen broth) enclosing I,ecitin and tween 80 as neutralization agent.
