Effects of tKCN (timing of KCN addition). (A) On time delay tL - tKCN. The solid curve shows the quadratic fit of y = 54.52 - 1.09x + 0.02(x - 36.57)2. Error bars indicate the associated SDs. As an example, when tKCN = 45 min, the observed tL is 50.11 min, thus the time delay is tL - tKCN = 5.11 min. (B) On lysis time SD (closed circles) and CV (closed triangles). Solid curve shows the quadratic fit of SD against tKCN (y = 13.24 - 0.28x + 0.01(x - 36.57)2).
