WebCrystal violet is commonly used when the biofilm is grown on the walls of the wells of a 96 well plate, or when biofilm is grown on pegs immersed in the wells (i.e., called the MBEC assay, an ASTM ...
WebTwo assays for quantification of S. aureus biofilm formation, the crystal violet (CV) assay and the XTT (tetrazolium salt reduction) assay, were optimized, evaluated, and further compared. In CV assay, most isolates formed weak biofilm 74.3 %), while the rest formed moderate biofilm (23.3 %) or strong biofilm (2.3 %). WebThe protocol described here outlines simple and reproducible methods for assessing the biofilm inhibition and eradication capacities of novel antibiofilm agents against adherent bacterial biofilms grown in 96-well microtiter plates. It employs two inexpensive dyes: crystal violet to stain adhered biofilm biomass and 2,3,5-triphenyl tetrazolium ...
