Environmental and energy security has now become a serious global problem, requiring a lot of research to find and implement its cost-effective and environmentally friendly alternatives. The development and use of renewable energy sources is necessary and important in order to avoid the emergence of a global economic crisis. One of the solution to prevent a future crisis caused by energy shortages is to introduce biofuels into the fuel market. Despite the fact that various forms of renewable energy are currently used, the prospects for the production of biofuels from cyanobacteria are quite high due to their unique properties, such as a high lipid content and a suitable fatty acid (FA) composition for the production of biofuels, their suitability for growing open water and the ability to grow on wastewater. The purpose of this article is to provide a comprehensive overview of the potential of cyanobacteria in the conversion of wastewater into biofuels. The article covers comparative data on the accumulation of lipids and the content of fatty acids in various representatives of cyanobacteria and their possibilities in the remediation of wastewater. Various approaches to the extraction of lipids from phototrophic microorganisms that are currently available, their advantages and disadvantages, and the results of the monitoring of the main key points of the development of the technology for converting cyanobacterial biomass into biofuels, with an emphasis on the existing barriers, effects and solutions, are also considered. Further research in this field is required for the successful implementation of this technology on an industrial scale.
环境和能源安全现在已经成为一个严重的全球性问题，需要进行大量的研究来寻找并实施具有成本效益且对环境友好的替代方案。为了避免全球经济危机的出现，开发和利用可再生能源是必要且重要的。为了防止因能源短缺而引发未来的危机，一种解决方案是在燃料市场引入生物燃料。尽管目前已经使用了各种形式的可再生能源，但由于蓝细菌具有独特的特性，如高脂质含量和适合生产生物燃料的脂肪酸 (FA) 组成、适合在开阔水域生长以及能够在废水上生长，因此从蓝细菌生产生物燃料的前景非常广阔。本文的目的是提供对蓝细菌将废水转化为生物燃料的潜力的全面概述。本文涵盖了关于各种蓝细菌代表积累脂质和脂肪酸含量的比较数据，以及它们在废水修复方面的可能性。还考虑了从光养微生物中提取脂质的各种现有方法、它们的优缺点，以及监测将蓝细菌生物质转化为生物燃料技术发展的主要关键点的结果，重点关注现有障碍、影响和解决方案。为了在工业规模上成功实施这项技术，需要在该领域进行进一步的研究。
