Abstract

Influence of nickel on grwoth, 14C-fixation and allocation of carbon among different biochemical fractions was investigated in Chloretla pyrenoidosa. Nickel significantly reduced the fresh and dry weights of chlorella cells. 14C-fixation was significantly reduced by increasing nickel concentration in growth media. 14C-allocation into different biochemical fractions was also markedly altered by nickel. Reduction in l4CO2 assimilation and carbon allocation into pigment-lipid fraction and residue fraction resulted in decreased chlorophyll content and dry weight.
