Abstract
Nitrogen (N2) fixation stands as an indispensable natural process for the survival of all life forms on Earth. Within the grand tapestry of the N2 cycle, biological N2 fixation plays a vital role. But its optimal manifestation may be constrained by the metabolic generation of reducing equivalents from chemical substrates. Therefore, it becomes important to propose reasoned and feasible strategies to improve the production of reducing equivalents and thereby enhance N2-fixation efficiency. In a recent publication within Angewandte Chemie International Edition, Bazan and coworkers reported a light-driven N2-fixing bacteria biohybrid system supported by a broad light-harvesting conjugated oligoelectrolyte (COE-IC) and non-photosynthetic bacteria of Azotobacter vinelandii (A. vinelandii). The introduction of the optically active COE-IC enhances the conversion of N2 to ammonia (NH3) and improves the photoinduced generation of biomass and L-amino acids of biological N2 fixation systems.
氮(N2)固定是地球上所有生命形式生存不可缺少的自然过程。在庞大的N2循环中,生物的N2固定起着至关重要的作用。但其最佳表现可能受到化学底物代谢产生还原性等价物的限制。因此,提出合理可行的策略来提高还原性当量的产生,从而提高固氮效率变得非常重要。在Angewandte Chemie International Edition最近发表的一篇文章中,Bazan及其同事报道了一种由广泛的光捕获共轭寡电解质(COE-IC)和非光合细菌Azotobacter vinelandii (a . vinelandii)支持的光驱动的n2固定细菌生物杂交系统。光学活性COE-IC的引入提高了N2到氨(NH3)的转化,并改善了生物N2固定体系中生物质和l -氨基酸的光诱导生成。
