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.

Key words： microalga; package effect; light attenuation; exponential model
