Minimum Inhibitory Concentration (MIC)

8 µg/mL
The lowest concentration showing no microbial growth (clear well).
💡

Expert Tip

MIC is defined as the lowest concentration of an agent that completely inhibits visible microbial growth. Use controls for validation.

Calculation Methodology & Details

📐

Formula

MIC = Concentration in the first well (highest dilution) that prevents growth.

Calculated by starting concentration C₀ divided by dilution factor raised to the power of well step: C = C₀ / (Factor^well_index).

How to Determine MIC

Follow these steps to find the MIC:

1

Set Start Concentration

Enter starting concentration (e.g. 64 µg/mL) and choose a 2-fold dilution.

2

Check Turbidity

Toggled wells represent bacterial growth. Growth is turbid (yellow), clear wells are inhibited.

3

Read the result

The lowest concentration well that remains clear (unchecked) is your MIC.
