Phytoplankton (both natural populations and cultures) have been concentrated 20‐fold to 200‐fold by passage through an ultrafiltration cell with continuous magnetic stirring. Conditions yielding maximum recovery of physiologically active phytoplankton have been developed. Recovery of 14 C‐carbon dioxide assimilation activity was comparable to that of chlorophyll, generally varying from 55–75% for natural populations and from 70–95% for cultures.
