Hydrogen injection reduces ammonia nitrogen and changes microbial community composition in aquaculture water

The study aimed to investigate the effect of hydrogen on nitrogen and phosphorus removal microbial community composition in aquaculture water. Two groups were designed separated: Group H was charged with D set as control. Water samples collected at 0, 1, 2, 3, 4, 5, 6, 7 days after injection detect not only content total nitrogen, ammonia phosphorus, but also Our findings have demonstrated that 7-days’ treatment could effectively reduce And Day 7, concentration 1.66 times H. Meanwhile, structures water bodies these two significantly different. abundance bacteria such Proteobacteria, Firmicutes, Bacteroidetes, Desulphuri a increased clearly H, which means nitrification denitrification occurred injection. These suggested improve health production be used functional external method protect environment.
