• 关键词: Algal-bacterial granule; N2 fixation; Carbon neutrality; Functional biomass

(1) The cyanobacteria dominated granule system was established using the mixture of NIES1726 and 1728 for nitrogen fixation, and the utilization of carbon and nitrogen species with or without N2 recirculation was examined.(2) The stability and performance of algal-bacterial granules were assessed by treating aquaculture water with almost no soluble N and organic C.(3) Six related high-quality articles were published with 15 reports (two keynote speeches)in international conferences during this fiscal year.

(1)利用NIES1726和1728的混合物建立了以蓝藻为主的固氮颗粒系统，并考察了有或没有N2再循环时碳氮物种的利用情况。(2)研究了藻菌颗粒的稳定性和性能。 (3) 期间在国际会议上发表相关高质量文章 6 篇，报告 15 篇（主题演讲 2 篇）。本财年。
