本文报道了通过光合作用固定二氧化碳的绿藻辐射特性的实验测量。产生的生物质不仅可用于生产生物燃料，还可用于动物饲料和人类消费的食品补充剂。特别关注了三个广泛使用的种，即葡萄孢子菌、小球藻和斜纹绿球菌。它们的消光系数和吸收系数是通过测量400-800 nm光谱范围内正常-正常和正常半球的透过率得到的。此外，利用极光散射比浊仪测量了微生物在632.8 nm处的散射相函数。观察到，对于所有菌株，散射超过吸收。消光和散射截面的大小是每个品系的大小、形状和叶绿素含量的函数。吸收峰位于435、475和676 nm，分别对应于叶绿素a和叶绿素b。这一结果可用于池塘或光生物反应器中CO2固定的定标和优化，以及可控生态生命支持系统的开发。(C)2009爱思唯尔有限公司。保留所有权利。
This paper reports experimental measurements of the radiation characteristics of green algae Used for carbon dioxide fixation via photosynthesis. The generated biomass can be used to produce not only biofuels but also feed for animal and food supplements for human consumptions. Particular attention was paid to three widely used species namely Botryococcus braunii, Chlorella sp., and Chlorococcum littorale. Their extinction and absorption coefficients were obtained from normal-normal and normal-hemispherical transmittance measurements over the spectral range from 400 to 800 nm. Moreover, a polar nephelometer was used to measure the scattering phase function of the microorganisms at 632.8 nm. It was observed that for all strains, scattering dominates over absorption. The magnitudes of the extinction and scattering cross-section are functions of the size, shape, and chlorophyll content of each strain in a nontrivial manner. Absorption peaks at 435,475, and 676 nm corresponding to chlorophyll a and chlorophyll b. The results can be used for scaling and optimization of CO2 fixation in ponds or photobioreactors as well as in the development of controlled ecological life support systems. (C) 2009 Elsevier Ltd.
