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 ). WebHowever, biofilm layer formed at the liquid-air interphase known as pellicle is extremely sensitive to its washing and staining steps. Early phase biofilms are also prone to damage by the latter steps. In bacteria like mycobacteria, biofilm formation occurs largely at the liquid-air interphase which is susceptible to loss.
