incubated
ciliate simultaneously with sufficient Dunaliella salina as
food and found that the cell densities of microalgae decreased from
2.7 104 cells/mL to 1.2 104 cells/mL after 2 days incubations.
This has also been reported by Moreno-Garrido and Canavate
(2001), who observed that grazing ciliates can clarify dense outdoor
mass cultures of Dunaliella salina within 2 days
