Assimilation kinetics of [1, 2-¹³C]-acetate during heterotrophy and mixotrophy in the presence of photosynthesis inhibitor atrazine.

<p>Assimilation kinetics of acetate and metabolite formation by <i>C. reinhardtii</i> during (A) heterotrophy and (B) mixotrophy following the addition of [1, 2-¹³C]-acetate to the TP medium containing atrazine (5 µM). Atrazine stock (10 mM) was prepared in water from where 5 µM atrazine was achieved. (The signs * and ** represent methyl and carboxyl peaks, respectively, of [1, 2-¹³C]-acetic acid, and the signs⁺and⁺⁺represent bicarbonate and CO₂^aq peaks, respectively).
