  1. aMeasures at 40 h of culturing
  2. bComputed through the linear regression of lipolytic activity (U/L) vs X (g/L)
  3. cComputed through the logistic model
  4. d+ and − represent high and low level, respectively, for factors ABCDEFG. 0 stands for a medium level which results from the average of the maximum and minimum value
