Experimental results indicating the relationship between isotopic fractionation and growth rate (μ) of an alga. Variations in (a) the carbon isotopic fractionation associated with CO2 assimilation (\( {\varepsilon}_{{\mathrm{CO}}_2} \)) by the freshwater green alga Chlamydomonas reinhardtii (modified from Takahashi et al. 1991) and (b) the nitrogen isotopic fractionation associated with nitrate assimilation (\( {\varepsilon}_{{\mathrm{NO}}_3} \)) by the marine diatom Phaeodactylum tricornutum (modified from Wada and Hattori 1978).
