4.2 Chemostat CultureThe chemostat model represents a somewhat novel approach for analysis <strong>of</strong>algal species with transitions to rest<strong>in</strong>g stages. From <strong>the</strong> ma<strong>the</strong>matical modelwe deduced thatMB∗NB∗ = 1 δ D + γ δ .Thus our model suggests that if <strong>the</strong> transition rates are constant, <strong>the</strong>n <strong>the</strong>y canbe calculated by know<strong>in</strong>g <strong>the</strong> steady state population values <strong>and</strong> <strong>the</strong> dilutionrate.References[1] Clodong, S. <strong>and</strong> Blasius, B., 2004.Chaos <strong>in</strong> a periodically forced chemostatwith algal mortality.
