Table 2 Cell surface hydrophobicity of Lactococcus strains

From: The streptococcal collagen-like protein-1 (Scl1) is a significant determinant for biofilm formation by group a Streptococcus

LactococcusStrain Actual Value Hydrophobicity Index
L. lactis 1363 WT 59.7 ± 7.2 100
L. lactis 1363::pJRS525 56.6 ± 5.5 98
L. lactis 1363::pSl230 82.0 ± 2.6 **137
  1. Actual hydrophobicity values were calculated based on hexadecane binding as described in Methods. Values are representative of three separate experiments with ten replicates ± SD
  2. Hydrophobicity Index represents the ration of actual hydrophobicity value for each strain to that of the isogenic wild-type (WT) strain multiplied by 100
  3. ** Asterisks denote a statistically significant difference of Δscl1 mutants versus WTs at P ≤ 0.001
