Growth curves and parameters of TMW 1.708 grown in mMRS supplemented with different Tween types. Cells from a 24 h pre-culture in mMRS without Tween supplement (mMRS-) were transferred (1% v/v) in fresh mMRS- or mMRS containing 1  g L^− 1 of either Tween 20 (mMRST20), Tween 40 (mMRST40), Tween 60 (mMRST60), or Tween 80 (mMRST80) and grown at 30 °C for 30 h. a Growth curves, b maximum OD₆₀₀, c maximum growth rate μ_max and d duration of lag phase Tl are depicted. The presented values are the means of at least three replicates. Error bars represent the standard deviation. Asterisks (*) mark data with statistically significant difference (p < 0.05)
