Microalgae and other phototrophic microorganisms can be cultivated to produce food and valuable bioproducts, also allowing to remove nutrients from wastewater and CO from biogas or polluted gas streams. Among other environmental and physico-chemical parameters, microalgal productivity is strongly influenced by the cultivation temperature. In this review, cardinal temperatures identifying the thermal response, i.e., the optimal growth condition (T), and the lower and upper limits for microalgae cultivation (T and T), have been included in a structured and harmonized database. Literature data for 424 strains belonging to 148 genera of green algae, cyanobacteria, diatoms, and other phototrophs were tabulated and analysed, with a focus on the most relevant genera that are currently cultivated at the industrial scale in Europe. The dataset creation aimed at facilitating the comparison of different strain performances for different operational temperatures and assisting in the process of thermal and biological modelling, to reduce energy consumption and biomass production costs. A case study was presented, to illustrate the effect of temperature control on the energetic expenditure for cultivating different Chorella sp. strains under a greenhouse located in different European sites.
微藻和其他光合微生物可以进行培养以生产食物和有价值的生物产品，还能从废水中去除营养物质，并从沼气或污染气流中去除一氧化碳。在其他环境和物理化学参数中，微藻生产力受培养温度的影响很大。在本综述中，确定热响应的临界温度，即最佳生长条件（T）以及微藻培养的下限和上限温度（T 和 T），已被纳入一个结构化且统一的数据库。对属于绿藻、蓝细菌、硅藻和其他光合生物的148个属的424个菌株的文献数据进行了制表和分析，重点关注目前在欧洲进行工业规模培养的最相关属。数据集的创建旨在便于比较不同菌株在不同操作温度下的性能，并协助进行热和生物建模过程，以降低能源消耗和生物质生产成本。还介绍了一个案例研究，以说明温度控制对在欧洲不同地点的温室中培养不同小球藻属菌株的能源消耗的影响。
