WebApr 18, 2024 · Sub-MICs (½ and ¼ MIC) of disinfectants solutions were tested for biofilm inhibition capacity. In case of ½ MIC, Opti-free was able to prevent 72.97% of tested isolates from biofilm formation. Perfect solution prevents 67.56% of tested isolates, while Renu was able to prevent only 29.72% of tested isolates (Fig. 1 ). Webthe level of biofilm formation by P. aeruginosa grown in TSB + 0.2% glucose (Figure 4) at an inoculum of 1 x 106 CFU/mL. Whether the CV1 or the CV2 method was used to measure biofilm formation, biofilm biomass increased over 8 to 16 hours. However, the biofilm level was generally higher with the CV2 method. Similar results were obtained
