Methods for high-throughput screening of anti-biofilm compounds are needed. In such assays,
Alamar Blue has been shown to be a more reproducible and cheaper redox indicator than XTT [55]
and is useful in identifying resistance-compromised mutants and identification of compounds with
anti-biofilm activity. The assay has been used to identify antimicrobials with enhanced efficacy against certain clinically important bacterial and fungal biofilms
