Before switching totally to alternative fuel stage, CO(2) mitigation process has considered a transitional strategy for combustion of fossil fuels inevitably. In comparison to other CO(2) mitigation options, such as oceanic or geologic injection, the biological photosynthetic process would present a far superior and sustainable solution under both environmental and social considerations. The utilization of the cyanobacteria Anabaena sp. CH1 in carbon dioxide mitigation processes is analyzed in our research. It was found that an original developed photobioreactor with internal light source exhibits high light utilization. Anabaena sp. CH1 demonstrates excellent CO(2) tolerance even at 15% CO(2) level. This enables flue gas from power plant to be directly introduced to Anabaena sp. CH1 culture. Double light intensity and increased 47% CO(2) bubble retention time could enhance CO(2) removal efficiencies by 79% and 67%, respectively. A maximum CO(2) fixation rate of 1.01 g CO(2)L(-1)day(-1) was measured experimentally.
在完全转向替代燃料阶段之前，CO(2)减排过程不可避免地考虑了化石燃料燃烧的过渡策略。与其他 CO(2)减排选择相比，如海洋或地质注入，生物光合作用过程在环境和社会考虑方面将提供一个更好和可持续的解决方案。我们的研究分析了蓝藻 Anabaena sp. CH1 在二氧化碳减排过程中的应用。研究发现，带有内部光源的原始开发光生物反应器具有高光利用效率。Anabaena sp. CH1 甚至在 15% CO(2)的水平下也表现出优异的 CO(2)耐受性。这使得电厂废气可以直接引入 Anabaena sp. CH1 培养物中。双光强度和增加 47%的 CO(2)气泡保留时间可分别将 CO(2)去除效率提高 79%和 67%。实验测量到的最大 CO(2)固定速率为 1.01 g CO(2)L(-1)day(-1)。
