Extract

Nutrient-limited batch cultures of two marine phytoplankton have been subjected to aeration and varying rates of mechanical agitation and the effects of growth and uptake of 14C and nutrients recorded. In both phosphate- and nitrate-limited cultures the lag period decreased with increasing agitation rate. Cell division times in the exponential phase decreased with increasing agitation of phosphate-limited cultures but increased in comparable nitrate-limited cultures. Division times were increased in all aerated cultures. The final yield of phosphorus-limited cultures was greatest at the highest agitation.
