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.

蓝藻在将废水转化为生物燃料方面的潜力

环境和能源安全现已成为一个严重的全球性问题,需要进行大量研究以找到并实施其具有成本效益和环保的替代方案。为了避免全球经济危机的出现,可再生能源的开发和使用是必要和重要的。防止能源短缺造成未来危机的解决方案之一是将生物燃料引入燃料市场。尽管目前使用了各种形式的可再生能源,但由于蓝藻具有独特的性质,例如高脂质含量和适合生产蓝藻的脂肪酸 (FA) 组成,因此从蓝藻生产生物燃料的前景非常广阔。生物燃料,它们在开放水域生长的适宜性以及在废水中生长的能力。本文的目的是全面概述蓝藻在将废水转化为生物燃料方面的潜力。该文章涵盖了各种蓝藻代表中脂质积累和脂肪酸含量的比较数据及其在废水修复中的可能性。目前可用的从光养微生物中提取脂质的各种方法,它们的优缺点,以及蓝藻生物质转化为生物燃料技术发展的主要关键点的监测结果,重点是现有的还考虑了障碍、影响和解决方案。要在工业规模上成功实施该技术,需要在该领域进行进一步研究。
