【 摘 要 】

References(10)Cited-By(6)In a photo-autotrophic microalgae culture, a linear functional relation between a specific growth rate and a light energy absorption rate has been adopted. However, this relation does not always hold for a wide range of variation of a specific light-absorption rate. Therefore, in this paper we have proposed a new model for growth kinetics as follows:μ = k(ξ – a)(1/n)k = α exp(–βIo)where μ is a specific growth rate, ξ is a specific light absorption rate and Io is an incident light intensity, and a, n, α, β are constants. The model was verified by experimental data obtained from a Chlorella ellipsoidea photo-aututrophic culture.
