Table 10.
IC50 values were determined using a modification of the broth microdilution method and biodegradation determined by a closed bottle test by Ferlin et al. in 2013 [55]. The values of IC50 reported in the table are expressed in millimolar; TBABr and TBAOH·30H2O were studied as reference classical salts.
