From: Enterococcus hirae biofilm formation on hospital material surfaces and effect of new biocides
The ability of E. hirae ATCC 10541 to form biofilm on polystyrene and stainless steel, at 20 and 37 °C and in vitro antibiofilm action of disinfectants LH IDROXI FAST and LH ENZYCLEAN SPRAY tested at the same conditions. The untreated and treated biofilms were analyzed for the biomass production, after 48 h of incubation, through Cristal Violet staining method. The results were expressed as average of OD595 values of three experiments (mean value ± SD). Symbol represents result statistically significant (p <0.05). In particular, § represents the statistically significant difference in the values observed between polystyrene and stainless steel at 37 °C
