摘要
有必要通过绿色微藻的光合代谢增加对太阳辐照的利用,以开发其作为脂质、碳水化合物、色素或芳香化合物来源的潜力,作为生物燃料或感兴趣的产品的来源。暴露在阳光下的微藻能够通过合成更多的色素来消散入射光能,从而控制细胞光系统的过饱和,但降低了光的利用效率。光驯化是由叶绿素质量含量与生物量中碳含量的关系(g Chl / g C)来描述的。在室外光生物反应器中,辐照度取决于地理位置、一年中的时间和大气条件。在本研究中,生物量的产生被建立为养分的动态函数,以C: N:Chl表示,养分的初级同化为硝酸盐(N)和铵态氮(a)。本研究结果表明,在不同的参数化情景下,G: C、N:C、Chl: C和生物量为C(碳)的演化呈现一致的结果。
Estudio de la evolución de C: N: Chl en microalgas verdes considerando la irradiación solar a través de un modelo dinámico
Increasing the use of solar irradiation by the photosynthetic metabolism of green microalgae is necessary to exploit its potential as a source of lipids, carbohydrates, pigments or aromatic compounds as a source of biofuels or products of interest. Microalgae exposed to sunlight are able to adapt by synthesizing a greater amount of pigment to dissipate the incident light energy, controlling the supersaturation of cellular photosystems but reducing the efficiency of the use of light. The photoacclimation is described by the content of chlorophyll mass in relation to the carbon content in the biomass (g Chl / g C). In an outdoor photobioreactor, irradiance depends upon geographical location, time of year and atmospheric conditions. In the present proposal, the generation of biomass is established as a dynamic function of the nutrients, represented as C: N:Chl and the primary assimilation of nutrients as Nitrate (N) and Ammonium (A). The results of this research show an evolution of G: C, N: C, Chl: C and biomass as C (carbon) in different scenarios of parameterization showing consistent results.
