Efficacy of disinfectants against static biofilms on stainless steel surface
2008
Pap, K. | Kiskó, G.
Inactivation and removing efficiency of disinfectants (Descosal and Domestos) was tested against <i>Pseudomonas aeruginosa</i> and <i>Candida albicans</i> and their biofilms (2 and 72 h, 3, 7 and 14 days old, respectively). The survival of microbes was studied by pour plating and impedimetry, and the attachment by epifluorescent microscopy.In the surface test, both disinfectants were effective against both test organisms with no significant difference in their efficiency. The decreasing detection times during impedimetric measurements showed higher resistance of the older <i>Ps. aeruginosa</i> biofilms. Both disinfectants tested were fungicidal against <i>C. albicans</i> and bactericidal against <i>Ps. aeruginosa</i> but for biofilm removal Domestos was more efficient.
