Phosphorus is an essential element for all life forms. It is a
mineral nutrient. Orthophosphate is the only form of P that
autotrophs can assimilate. Extracellular enzymes hydrolyze
organic forms of P to phosphate. The effect is studied of
different phosphorous concentration on changes in growth
rate of diatom species isolated from Tones River. All
diatoms examined increasing cell division rate with
increasing phosphorous concentration in the medium.
Diatoms, however, were not able to dominate when
phosphate was deficient, although silicate and nitrate were
in excess.
