The nutritional value of the marine cryptophyte Rhodomonas lens for the filter feeder Brachionus plicatilis as well as its biotechnological potential as a source of phycoerythrin (PE) and polyunsaturated fatty acids (PUFA) were evaluated in semi-continuous cultures maintained with different daily renewal rates (RR), from 10% (R10) to 50% (R50) of the total volume. Steady-state cell density decreased from 22 to 7 × 10 cells mL with increasing RR, with the maximum cell productivity, nearly 0.4 g L day, observed with R40.
