Aquaponics is a solution for sustainable production of fish and plants in a single semi-closed system, where nutrient-rich water from the aquaculture provides nutrients for plant growth. We examined the microbial communities within an experimental aquaponics system. Whereas the fish feces contained a separate community dominated by bacteria of the genus Cetobacterium, the samples from plant roots, biofilter, and periphyton were more similar to each other, while the communities were more diverse. Detailed examination of the data gave the first indications to functional groups of organisms in the different compartments of the aquaponic system. As other nitrifiers other than members of the genus Nitrospira were only present at low numbers, it was anticipated that Nitrospirae may perform the nitrification process in the biofilm.
鱼菜共生是一种在单一半封闭系统中可持续生产鱼类和植物的解决方案，其中来自水产养殖的富营养水为植物生长提供养分。我们研究了一个实验性鱼菜共生系统中的微生物群落。鱼粪便中含有一个以鲸杆菌属细菌为主的独立群落，而来自植物根系、生物过滤器和附生植物的样本彼此更相似，同时群落更加多样化。对数据的详细检查首次揭示了鱼菜共生系统不同隔室中生物功能群的情况。由于除硝化螺菌属成员外的其他硝化细菌数量很少，预计硝化螺菌可能在生物膜中进行硝化过程。
