Figure Lengend Snippet: Mechanism of action of H 2 S. ( A ) CLSM images of 12 h pre-incubated T. rubrum ATCC 28,188 exposed to NaHS in RPMI-GM medium (pH 5) for 2 h, at a sulphide concentration that is equivalent to 3.4 µg/mL of H 2 S. The samples were stained with Calcofluor white and DCHF-DA. ( B ) 60 µg/mL of the antioxidants N-acetylcysteine (NAC) and reduced glutathione (GSSH) counteract the effect of H 2 S on T. rubrum . ( C ) Effect of H 2 S on cytochrome c oxidase activity in isolated mitochondria from T. rubrum . Statistical analysis was done by a One-way ANOVA followed by Dunnett’s multiple comparison test (** p < 0.01; *** p < 0.001, n = 3). ( D ) 5-IAF labelling of proteins from T. rubrum conidia, separated by SDS-PAGE. (Left) Coomassie brilliant blue stain of the gel showing molecular weight marker bands (in kDa) and protein extracts from samples that were untreated ( −) or treated with NaHS ( +) for 3 h. (Right) 5-IAF labelled proteins.
