📄 Abstract（原文）
This chapter provides a comprehensive description of the multifaceted role of microalgae in renewable biofuels production, exploring their physiology, cultivation systems, extraction and conversion technologies, environmental impacts, and economic aspects. Utilizing wastewater can reduce the need for fertilizer and water in microalgal cultivation, resulting in high biomass yields, significant improvements in overall economics, and substantial environmental benefits. Microalgae cultivation systems can be categorized into two types, which are open systems and closed systems. Microalgal biomass production entails significant carbon sequestration potential, with the requirement of 1.8/kg CO 2 per kg microalgal biomass produced. Microalgae-based wastewater treatment systems offer a systematic approach, whereby nutrient removal via assimilatory mechanisms and subsequent biomass recovery approach, whereby nutrient removal via assimilatory mechanisms and subsequent biomass recovery are accomplished simultaneously with CO 2 fixation from the atmosphere or point sources. The chapter describes the bioproducts of microalgae for biofuels production and discusses downstream processing for biofuel conversion.
