Pseudo-nitzschia granii (Hasle) Hasle
Size:
Cell size in a laboratory isolate gradually decreases over time. The average cell volume of a northeast Pacific isolate was 425 ± 5 microns (Lundholm et al. 2004).
Distribution:
Pseudo-nitzschia granii is restricted to cold waters.
Ecology:
A northeast Pacific strain of P. granii had a maximum specific growth rate of 1.81 ± 0.05 per day and a maximum pH for growth of 9.1 in laboratory experiments (100 micromolar photons m-2 s-1 and 15 deg C; Lundholm et al. 2004).
