Minimum inhibitory concentration of MoWa against MRSA and MSSA strains. S. aureus strain (A) NRS408, (B) NRS49, (C) NRS236, (D) NRS230, or (E) NRS242 was inoculated in a six-well plate and treated with a mixture levulinic acid (LA) and SDS at a concentration of 1/0.04 M, 0.52/0.02 M, or 0.26/0.01 M for 1 h. Bacteria were removed, diluted and plated onto BHI agar plates containing 7% of NaCl to obtain colony counts (cfu/ml). Error bars represent the standard errors of the means calculated using data from at least three independent experiments. *p<0.05 compared to control.
