^aThe indicated compounds were added to MNG medium at a final concentration of 3 mM, and the cultures were incubated for 30 h.

^bThe LOD (RFU·min⁻¹·OD₆₀₀⁻¹·ml⁻¹) is expressed as a percentage with respect to the activity detected in medium with l-Lys. ND, not detected.

^cNo growth was observed in this medium.
