Figure 6From: Staphylococcus aureus immunodominant surface antigen B is a cell-surface associated nucleic acid binding proteinMicrotiter plate assay for biofilm formation. Strains SA113 and 10833 and their isogenic isaB deletion mutants were screened for their ability to form biofilms in different media; TSB, TSB+1% glucose and 3.5% NaCl, BHI, BHI+1% glucose, LB, or LB+1% glucose. A. Safranin-stained biofilms and B. Average OD595 nm values of 8 wells from three separate experiments (24 values) of solubilized safranin-stained biofilms. Deletion of isaB did not reduce biofilm formation under any conditions tested but there was a statistically significant increase in OD595 nm in the absence of isaB in LBG.Back to article page
