摘要

摘要:本文探讨了光养生物在替代能源中的作用,重点介绍了单细胞藻类。特别关注的是利用生物燃料电池(植物和酶生物燃料电池进行讨论)来发电的光养生物。这项研究的重点是微生物燃料电池(MFC),它与电力一起,可以获得生物燃料和生物氢。本文阐述了限制MFC功率的因素,以及克服这些因素的方法。例如,为了减少过电压造成的MFC功率损失,似乎有希望开发各种光生物反应器。微光养生物在MFC中的应用,通过设计强制照明的自养光生物反应器,导致了光合MFC(或PhotoMFC)的发展。它们允许通过光合作用产生氧气,无论是原位还是非原位,通过将氧气从光生物反应器再循环到阴极室。这里可以使用人工氧化还原介质,将电子直接从非催化阴极转移到由藻类光合作用形成的O2上。生物催化阴极已被证明比化学催化剂产生更少的能量。值得注意的是,带有微藻的MFC装置允许利用更广泛的不同连接————污水和污水的组成部分:有机酸、糖、醇、脂肪和其他基质。利用光养生物生产生物燃料具有特别的意义。微藻可以生产几种不同类型的可再生生物燃料,其生产可以与废水处理、二氧化碳捕获和各种化合物的生产相结合。

Phototrophs in alternative energy
Abstract: The role of phototrophs is examined in alternative energy, with the main emphasis on unicellular algae. Particular attention is paid to the use of phototrophs for generating electricity using biofuel cells (plant and enzymatic biofuel cells are discussed). This study focuses on microbial fuel cells (MFC), which, along with electric power, allow obtaining biofuels and biohydrogen. This article explains the factors limiting the MFC power, and ways of overcoming them. For example, it seems promising to develop various photobioreactors in order to reduce the loss of MFC power due to overvoltage. The use of microphototrophs in MFC has led to the development of photosynthetic MFC (or PhotoMFC) through the design of autotrophic photobioreactors with forced illumination. They allow generating oxygen through photosynthesis, both in situ and ex situ, by recirculating oxygen from the photobioreactor to the cathode chamber. Artificial redox mediators can be used here, transferring electrons directly from the non-catalytic cathode to O2, formed as a result of the photosynthetic activity of algae. Biologically catalyzed cathodes have been proven to generate less power than chemical catalysts. It is noted, that the MFC installations with the micro-algae allow utilizing a wider circle of different connections – the components of effluents and withdrawals: organic acids, sugar, alcohols, fats and other substrata. The use of phototrophs for the production of biofuels is of special interest. Several different types of renewable biofuels can be produced from microalgae, the production of which can be combined with wastewater treatment, CO2 capture and production of various compounds.
