Why in second phase?

But most antibiotics are obtained in stationary phase.

Then how in 2nd phase?

Please I need a better explanation on why it is the second phase (a phase known for optimum growth and no or little production).

The maximum growth occurs in stationary phase. It should be in third phase.
