As [Nisin] increases, [Cell] also increases, indicating that nisin is the primary
metabolite.
No. Cell growth is only hindered when sugar concentration drops. Meaning
that, this data cannot support such argument.
No. Nisin production ge

Definition
The Laplace transform of a function, f(t), is defined as:
Important analytical method for solving linear ordinary
differential equations.
F ( s ) = L [ f (t ) ] = f ( t ) e - st dt
