WebBiofilm was quantitated by crystal violet staining. Red columns represent the amount of biofilm formed by A. baumannii (wild type and abaI mutant, respectively) without the addition of AHL ... WebBiofilm protects bacteria from stress and hostile environment. Crystal violet (CV) assay is the most popular method for biofilm determination adopted by different laboratories so far. However, biofilm layer formed at the liquid-air interphase known as pellicle is extremely sensitive to its washing and staining steps.
