Classification criteria for biofilms along with optical densities obtained in this study
| Criteria for classification | Optical density values |
|---|---|
| OD ≤ ODcut = Nonbiofilm former (NBF) | OD is < 0.37 |
| ODcut < OD ≤ 2 × ODcut = Weak biofilm-former (WBF) | 0.38< OD ≤ 0.74 |
| 2 ODcut < OD ≤ 4 × adequate = Moderate biofilm-former (MBF) | 0.74 < OD ≤ 1.48 |
| OD >4 × ODcut = Strong biofilm-former. | OD >1.48 |
