Filter pore size for phytoplankton
Webpore filter is equivalent to its nominal pore size, effective pore size of the 5-pm Nitex screen is actually closer to 7-8 pm (Fig. 2); the latter probably reflects a manufacturing … WebResults of the first method showed that plankton cells larger than 5 μm were responsible for 2% of the total orthophosphate uptake rate. 98% of the total uptake rate occurred in plankton composed mostly of bacteria, which passed the 5 μm screen and were retained by the 0.45 μm pore-size filter.
