Dunaliella tertiolecta (Butcher) 在恒化培养物中以各种铵限制生长速率生长。铵的添加导致光合作用碳固定的快速暂时抑制。铵诱导的光合作用抑制的程度随着铵限制的严重程度而增加。细胞生长速度大于约。 80%μmax 对添加限制性养分没有表现出光合作用抑制。光合抑制的持续时间与添加铵盐的浓度有关。抑制后，光合作用相对于对照组立即增强。最终的增强程度随着添加的铵浓度的增加而增加。报告了稳态细胞叶绿素浓度、光合速率和同化数。
Dunaliella tertiolecta (Butcher) was grown in chemostat culture over a wide range of ammonium limited growth rates. The addition of ammonium caused a rapid temporary suppression of photosynthetic carbon fixation. The magnitude of ammonium induced photosynthetic suppression increased with the severity of ammonium limitation. Cells growing at rates greater than ca. 80%μmax exhibited no photosynthetic suppression in response to additions of the limiting nutrient. The duration of photosynthetic suppression was related to the concentration of added ammonium. Immediately following the suppression, photosynthesis was enhanced with respect to the controls. The eventual degree of enhancement increased with the concentration of added ammonium. Steady‐state cellular chlorophyll concentrations, photosynthetic rates, and assimilation numbers are reported.
