Impact of Deficiencies in Branched-Chain Fatty Acids and Staphyloxanthin in Staphylococcus aureus

Figure 4

Membrane fluidity of S. aureus strain SH1000 and derivative lpdA, crtM, and crtM:lpdA mutants. Cells from mid-exponential phase cultures were washed and incubated with DPH. Membrane fluidity was measured with a spectrofluorometer. Values represent average of three independent experiments ± standard deviation ( significant at p≤.05).
