本研究提出了一个简单的一维模型来估算平板光生物反应器中光合作用微生物在间歇培养过程中的线性生长速率。克氏小球藻作为一种模式微生物，在光生物反应器中以发光二极管(LED)为光源进行光自养培养。通过调节光照强度和培养高度来模拟不同的条件。通过将所测得的线性增长率与由该模型得到的预测值进行比较，验证了该模型的有效性。据此，提出了K.μm/α.Log(I0 I.S(e-1)I.c-e)作为高密度藻类在光限光条件下获得最大光产量的近似指标和提高光合作用生产力和效率的控制参数。
The current study proposes a simple monodimensional model to estimate the linear growth rate of photosynthetic microorganisms in flat-plate photobioreactors (FPPBRs) during batch cultivation. As a model microorganism, Chlorella kessleri was cultivated photoautotrophically in FPPBRs using light-emitting diodes (LEDs) as the light sources to provide unidirectional irradiation in the photobioreactors. Various conditions were simulated by adjusting both the intensity of the light and the height of the culture. The validity of the proposed model was examined by comparing the linear growth rates measured with the predicted ones obtained from the proposed model. Accordingly, the value of K.μm / α.L log(I 0 .I s (e-1).I c -e) was proposed as an approximate index for strategies to obtain the maximal lightn yield under light-limiting conditions for high-density algal cultures and as a control parameter to improve the photosynthetic productivity and efficiency.
