紫球藻培养液光衰减规律的研究

Study on the Light Decline Model of Porphyridium cruentum Culture

对影响光衰减过程的主要因素进行了研究。结果表明，入射光强的大小对光衰减过程没有关系，而对细胞浓度和培养液的深度有直接的影响：进一步的研究表明紫球藻培养液中光照强度（Ⅰ）、紫球藻浓度（ＯＤ）及培养液深度（ｈ）之间的关系可以用一个比较直观的数学模型Ｉｎ（Ⅰ／Ⅰｏ）＝［－０．２８１３·ｌｎ（ＯＤ）－０．７２５］· ｌｎ（ｈ）－０．７７４５·ｌｎ（ ＯＤ）－ ０．８５５来表达。

A light decline mathematical model of Porphyridium cruentum is established. The results show that the relations between light density (l), cell concentration (OD ) and culture depth (h) of the Porphyridum cruentum culture liquid could be described with the mathematical model of ln (I/ Io) = [-0.2813· ln (OD )- 0.725 ]· ln (h ) - 0.7745· ln (OD) - 0.855.
