MBC values for S. aureus, S. epidermidis, P. aeruginosa, and E. coli after treatment with aqueous solutions of gentamicin sulfate salt (G), C60 fullerenol (60F), and gentamicin functionalized C60 fullerene (60FGG).
| Bacteria | Minimum Bactericidal Concentration (MBC) a μg/mL | ||
|---|---|---|---|
| G | 60F | 60FGG | |
|
S. aureus ATCC 25923 |
0.25 | NT b | 0.25 |
|
S. epidermidis ATCC 12228 |
0.5 | NT b | 0.5 |
|
P. aeruginosa ATCC 27859 |
0.25 | NT b | 0.25 |
|
E. coli ATCC 25922 |
1 | NT b | 1 |
a Minimum Bactericidal Concentration (MBC)–the lowest compound concentration that decreased the number of colonies by ≥99.99% compared to the control growth. b NT (not tested). Lack of antibacterial activity was determined already during MIC evaluation.
