a. C4: N‐Butyryl‐dl‐homoserine lactone.
b. C6: N‐Hexanoyl‐l‐homoserine lactone.
c. 3OC8: N‐(3‐Oxooctanoyl)‐l‐homoserine lactone.
d. +: AHL inhibition, inhibition of pigment production.
e. −: no AHL inhibition, no inhibition of pigment production.
f. −/+: weak response of AHL inhibition. Comparison of pigment production inhibition in respect to the control.
