---|---|---|
Childonella sp. | Tetrahymena sp. | |
P. costantinii | 3,225 ± 526 | 22,590 ± 8,632 |
S. plymuthica | 2,602 ± 331 | 24,750 ± 2,888 |
P. costantinii + S. plymuthica | 2,306 ± 548 | 31,320 ± 5,803 |
Either 500 Chilodonella sp. cells ml−1 or 100 Tetrahymena sp. cells ml−1 were initially added to biofilms.
