Nannochloropsis oculata was grown in an outdoor bubble column photobioreactor. To obtain information about the behaviour of microalgae/photobioreactor system related to the CO(2) net balance, an analysis of the pH profiles during microalgae growth was carried out. The use of the carbonate equilibrium chemistry and the overall CO(2) volumetric mass transfer in the photobioreactor has permitted to obtain information of the CO(2) losses/CO(2) microalgae consumption ratios. The simplicity of the technique used (a pH probe) could extend the use of this methodology for the correct selection of the photobioreactor/microalgae parameters with the aim to maximize the [CO(2) uptaken/(CO(2) uptaken+CO(2) stripped)] ratios.
眼点拟微绿球藻在户外鼓泡式光生物反应器中培养。为了获得与 CO2 净平衡有关的微藻/光生物反应器系统行为的信息，对微藻生长过程中的 pH 曲线进行了分析。利用碳酸盐平衡化学和光生物反应器中的总 CO2 体积传质，可获得 CO2 损失/CO2 微藻消耗比的信息。所用技术（pH 探头）简单，可扩展该方法的应用，以正确选择光生物反应器/微藻参数，从而最大限度地提高[CO2 吸收量/(CO2 吸收量+CO2 吹脱量)]比值。
