| Organism | Relevant characteristic | Alchivemycin A MIC (μg/ml) |
|---|---|---|
| Micrococcus luteus | Gram positive | 0.06 |
| Bacillus subtilis | Gram positive | 40 |
| Staphylococcus aureus | Gram positive | >50 |

The MICs were determined by the 2-fold sequential dilution method in heart infusion broth (Difco). The inhibition concentration was determined by measuring the absorbance at 600 nm.
