Microalgae are a diverse group of photosynthetic microorganisms of significant interest to the biotechnology industry, either as a sustainable source of natural compounds, or as light-driven cell factories to produce recombinant metabolites and proteins. Their ability to utilise light, CO₂, and basic nutrients leads to a simple and low-cost phototrophic cultivation process. This is particularly relevant to low- and middle-income countries, all of which require a cultivation system that is cheap, technically simple to operate, readily scalable, and can meet basic Good Manufacturing Practice requirements. A disposable ‘hanging bag’-type photobioreactor operated as a bubble column fits these criteria.

用于低成本微藻培养的简单“吊袋”光生物反应器的表征

微藻是生物技术行业非常感兴趣的一组多样化的光合微生物，它们既可以作为天然化合物的可持续来源，也可以作为光驱动的细胞工厂生产重组代谢物和蛋白质。它们利用光、CO ₂和基本养分的能力导致了简单且低成本的光养培养过程。这与低收入和中等收入国家尤其相关，所有这些国家都需要一种价格低廉、操作技术简单、易于扩展且能够满足基本良好生产规范要求的种植系统。作为气泡柱操作的一次性“吊袋”型光生物反应器符合这些标准。
