Table 5 Effect of NaCl on the micellar size distribution of the crude rhamnolipid mixture and the mono-rhamnolipid and di-rhamnolipid congeners determined by DLS analysis. The concentrations of the crude rhamnolipid mixture, mono-rhamnolipids and di-rhamnolipids were 1.5, 1.0 and 0.5 g/L, respectively. The results represent the average of 10 measurements ± standard deviation. ND: not determined.
