Abstract: A new exponential model of light attenuation, Ka=Kam+Cexp(-eX), was proposed on the basis of package effect theory and light attenuation experiments in different microalgal suspensions. The correlation coefficient of this model was evaluated as over 0.99 based on the experimental data from literatures. The minimum attenuation coefficient Kam, constant parameter C and proportional coefficient e were dependent on the types of microalgae, but the value of Kam+C was relatively stable. Moreover, the value of actual attenuation coefficient Ka in Synechococcus sp. PCC7942 was about 240 m2/kg in spite of the alteration of pigment content.

摘要： 基于藻细胞对光的包裹效应并结合藻细胞的光衰减数据，建立了藻细胞培养的光衰减指数模型，Ka=Kam+ Cexp(-eX)，以文献数据对其进行了检验. 结果表明，模型与文献数据的拟合相关系数分别为0.99965和0.99832. 不同藻细胞对最小比消光系数Kam、参数C和比例系数e有影响，但Kam+C值相对稳定. 色素含量对比消光系数Ka有一定影响，Synechococcus sp. PCC7942的Ka约为240 m2/kg.
