Since reagents may vary, each laboratory must determine the amount of KOH required. Hold the completed medium at 50 °C, pour a 10 mL sample, and check the pH at room temperature. When necessary, adjust the completed medium with either 1.0 N KOH or 1.0 HCl. Note that the pKa of ACES buffer is 6.9 at 20 °C and 6.8 at 25 °C.

Agar diffusion was first used by Martinus Beijerinck in 1889 to study the effect of auxins on bacterial growth. However, the method has been developed, refined and standardized by many scientists and scientific organizations over the years including George F. Reddish, Norman Heatley, James G. Vincent, [8] Alfred W. Bauer, William M.M. Kirby, John C. Sherris, [4] [5] Hans Martin Ericsson, the ...
