Table 4.
Growth inhibition percentages obtained for Aspergillus carbonarius MUM 05.18 with the purified mono-rhamnolipid and di-rhamnolipid congeners. The assays were performed at different concentrations of the purified rhamnolipid congeners with and without NaCl, at 25 °C for 5 days. The results represent the average of three independent experiments ± standard deviation. [RL]: concentration of mono-rhamnolipid or di-rhamnolipid congeners. NT: not tested.
