Spreading of S. aureus HG001 on TSA medium.

An overnight culture of S. aureus HG001 cultured in 3 ml TSB was washed with the same medium volume of PBS before inoculation. TSA plates (15 ml, 20 ml and 25 ml) that contained 0.25, 0.3, 0.35 and 0.4% agarose were inoculated with 2 μl of the bacteria. The plates were incubated at 37 °C for 24 h.
