Abstract

Microalgae cultivation using wastewater has been conducted to treat wastewater and lower carbon footprints. Wastewater can contribute to microalgae culture by supplying nutrients such as nitrogen, phosphorus, and organic carbon sources. Meanwhile, greenhouse gas emissions from fossil fuel consumption are also increasing rapidly, and global warming is intensifying. To overcome this phenomenon, Carbon Capture, Utilization, and Storage technology, a highly efficient greenhouse gas treatment technology that can capture and separate CO₂, has been developed and comprehensively discussed in this review. As a technology for capturing carbon, microalgae are cultured by supplying high concentrations of CO₂ using industrial flue gas. In addition, microalgae are used for removing organic substances, phosphorus, and nitrogen in wastewater. Through such biological treatment processes, it is possible to simultaneously reduce CO₂, remove biocontaminants, and produce high-value-added substances. Recently, research has been conducted on promoting microalgae growth by supplying wastewater and flue gas by enabling mixotrophic cultivation of microalgae. The review finally provides that sewage and industrial flue gas have the potential to improve the productivity of microalgae, reduce cost, and encourage environmental sustainability.

利用废水和烟气提高微藻的生物量和高价值产品

利用废水进行微藻培养，处理废水，降低碳足迹。废水可以通过提供氮、磷和有机碳源等营养物质来促进微藻培养。与此同时，化石燃料消费产生的温室气体排放量也在迅速增加，全球变暖正在加剧。为了克服这一现象，碳捕集利用与封存技术(Carbon Capture, Utilization, and Storage technology)是一种能够捕获和分离CO2的高效温室气体处理技术。作为一种捕获碳的技术，微藻是通过使用工业烟气提供高浓度二氧化碳来培养的。此外，微藻还可用于去除废水中的有机物、磷和氮。通过这种生物处理工艺，可以同时减少二氧化碳，去除生物污染物，并产生高附加值物质。近年来，人们对微藻进行了混合营养培养，通过提供废水和烟气来促进微藻生长的研究。本综述最后指出，污水和工业烟气具有提高微藻生产力、降低成本和促进环境可持续性的潜力。图形抽象

期刊介绍： Phytochemistry Reviews is the sole review journal encompassing all facets of phytochemistry. It publishes peer-reviewed papers in six issues annually, including topical issues often stemming from meetings organized by the Phytochemical Society of Europe. Additionally, the journal welcomes original review papers that contribute to advancing knowledge in various aspects of plant chemistry, function, biosynthesis, effects on plant and animal physiology, pathology, and their application in agriculture and industry. Invited meeting papers are supplemented with additional review papers, providing a comprehensive overview of the current status across all areas of phytochemistry.
