Fig. 2From: Celastrol mitigates staphyloxanthin biosynthesis and biofilm formation in Staphylococcus aureus via targeting key regulators of virulence; in vitro and in vivo approachIn vitro pigment inhibition by celastrol. (A) Inhibition of S. aureus ATCC 6538 pigment production in the presence of increasing concentrations of celastrol. (B) Half maximal inhibitory concentration (IC50) of celastrol against S. aureus ATCC 6538. Data shown represent the mean ± standard error from triplicate experimentsBack to article page
