As photoautotrophic microorganisms, microalgae feature complex mechanisms of photosynthesis and light energy transfer and as such studying their intrinsic growth kinetics is fairly difficult. In this article, the quantum yield of photochemical reaction was introduced in a study of microalgal kinetics to establish an intrinsic kinetic model of photoautotrophic microalgal growth. The blue-green algae Synechococcus sp. PCC7942 was used to verify the kinetic model developed using chlorophyll fluorescence analysis and growth kinetics determination. Results indicate that the kinetic model can realistically reflect the light energy utilization efficiency of microalgae as well as their intrinsic growth kinetic characteristics. The model and method proposed in this article may be utilized in intrinsic kinetics studies of photoautotrophic microorganisms.
作为光合自养微生物，微藻具有复杂的光合作用和光能传递机制，因此研究其内在生长动力学相当困难。本文在研究微藻动力学时引入光化学反应量子产率，建立了光合自养微藻生长的内在动力学模型。采用叶绿素荧光分析和生长动力学测定法，对蓝藻聚球藻 PCC7942 进行了验证。结果表明，该动力学模型能够真实地反映微藻的光能利用效率及其内在的生长动力学特性。本文提出的模型和方法可用于光合自养微生物的内在动力学研究。
