人们日益认识到，由于供应枯竭以及这些燃料向大气中排放温室气体而造成气候变化，化石燃料的广泛使用是不可持续的。微藻是替代性可再生可持续能源，因为它们具有生产大量生物质的高潜力，而生物质又可用于大规模生产不同的第三代生物燃料。微藻将太阳能转化为碳储存产物，导致脂质积累，包括TAG（三酰甘油），然后可以转化为生物柴油，生物乙醇和生物甲醇。本文综述了目标生物能源载体菌株的筛选、生产和积累及其优势，以及在石油、生物柴油、乙醇、甲醇、沼气生产和温室气体减排等方面的技术发展。该菌株的生物质原料适合于生产生物燃料。目前用于生产作为生物燃料的主要产品的混合技术（生物质生产、废水处理、温室气体缓解）的进展提供了大气污染控制，例如减少温室气体（CO2固定），将废水处理与微藻生长相结合。高效菌株的筛选、微生物代谢、培养体系、生物量的产生是微藻生物柴油生产技术可行性的关键。(C)2014爱思唯尔有限公司版权所有。
The extensive use of fossil fuels is increasingly recognized as unsustainable as a consequence of depletion of supplies and the contribution of these fuels to climate change by GHG (greenhouse gas) emissions into the atmosphere. Microalgae indicate alternative renewable sustainable energy sources as they have a high potential for producing large amounts of biomass which in turn can be used for production of different third-generation biofuels at large scale. Microalgae transform the solar energy into the carbon storage products, leads to lipid accumulation, including TAG (triacylglycerols), which then can be transformed into biodiesel, bioethanol and biomethanol. This paper reviews the selection, production and accumulation of target bioenergy carrier's strains and their advantages as well as the technological development for oil, biodiesel, ethanol, methanol, biogas production and GHG mitigation. The feedstock of promising algal strain exhibits the suitable biofuel production. The current progress of hybrid-technologies (biomass production, wastewater treatment, GHG mitigation) for production of prime-products as biofuels offer atmospheric pollution control such as the reduction of GHG (CO2 fixation) coupling wastewater treatment with microalgae growth. The selection of efficient strain, microbial metabolism, cultivation systems, biomass production are key parameters of viable technology for microalgae-based biodiesel-production.
