(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)以NIES1726和1728为固氮菌，建立了蓝藻占优势的颗粒污泥系统，并研究了N2回流和无N2回流条件下蓝藻对碳、氮物种的利用。(2)通过处理几乎不含可溶性氮和有机碳的养殖水体，对藻菌颗粒剂的稳定性和性能进行了评价。(3)在本财政年度，在国际会议上发表了6篇相关的高质量文章和15份报告（两次主旨发言）。
