| Substances | MIC (µg/mL) | MBC (µg/mL) | MBC/MIC Ratio |
|---|---|---|---|
| COS | 2048 | 2048 | 1 |
| EGCG | 1024 | 2048 | 2 |
| COS-CAT | 256 | 2048 | 8 |
| COS-GAL | 2048 | 2048 | 1 |
| COS-CAF | 2048 | 2048 | 1 |
| COS-FER | 2048 | 2048 | 1 |
| COS-EGCG | 1024 | 1024 | 1 |
COS: chitooligosaccharide; CAT: catechin; GAL: gallic acid; CAF: caffeic acid; FER: ferulic acid; EGCG: epigallocatechin gallate; MIC: minimum inhibitory concentration; MBC: minimum bactericidal concentration.
