“…The enrichment and screening media were formulated according to the procedure described by Yu, Wang, Guo, Shen, and Gu (2012), with appropriate adjustments. The enrichment medium contained glucose (5.0 g/L), (NH 4 ) 2 SO 4 (1.0 g/L), FeSO 4 Á7H 2 O (0.4 g/L), and MgSO 4 Á7H 2 O (0.5 g/L).…”

To investigate the feasibility of using micro‐organisms for ammonia‐N removal, six strains were isolated from Chinese white shrimp, Fenneropenaeus chinensis, seawater culture ponds in Dongying (Shandong, China). Of these, strain DY‐01, which exhibited the highest capacity to degrade ammonia‐N, removed 61.7% of the total ammonia‐N (50 mg/L) in 8 hr. An investigation of the factors affecting the removal efficiency indicated the optimum conditions to be 30°C, pH 8.0, and a salinity level of 30 g/L; 16S rDNA gene sequencing and biochemical analysis identified strain DY‐01 as Cobetia amphilecti, which has not previously been reported to degrade ammonia‐N. This strain also boosted the growth of Pacific white shrimp, Litopenaeus vannamei (p < .05), at a concentration of 107 CFU/mL, with no harmful effects on the shrimp's immune system. This study has thus identified a novel aerobic nitrifying bacterium that is potentially an excellent candidate for improving the water quality in mariculture ponds.

“…If it heavy metal in the aquatic ecosystem, especially in fisheries and shrimp farms, the result causes deleterious effects in all living organisms, including microbial survival of ammoniadegrading bacteria [4]. These bacteria are required because they can naturally eliminate ammonia pollutants in fisheries that come with feed [5]. The Heavy metal lead (Pb) is toxic, which affects the existence of microorganisms in waters.…”

Water hyacinth (Eichhornia crassipes) has been extensively used for heavy metal phytoremediation and stimulating microorganism growth in the effort to break down organic pollutants by the exudate secreted by the plant. This study aims to figure out the growth of the ammonia-degrading bacteria population and figure out the physical changes occurring in water hyacinth during the Pb phytoremediation process. The phytoremediation method was performed under the batch system with the treatments: P1 with water hyacinth for groundwater with 2 ppm of Pb; P2 with water hyacinth for groundwater with 4 ppm Pb; and P0 with no water hyacinth and Pb addition. Observations include the growth of ammonia-degrading bacteria, ammonia concentration, Pb analysis, observation of physical changes, and measurement of biomass of the water hyacinth. Results show that the nitrifying bacteria population growth rate was higher in the 2 ppm Pb treatment than in the 4 ppm Pb treatment. The implication was that there occurred a higher ammonia concentration decrease in P1 by 0.43 mg/L from the initial concentration of 1.21 mg/L. As for the water hyacinth's physical changes, a lower growth rate happened to the 4 ppm Pb treatment, resulted in lower biomass of 75.46 g in the said treatment than in the 2 ppm Pb (79.00 g). The use of water hyacinth in phytoremediation also prompted the bacterial growth to break down organic waste, but high concentrations of heavy metals will influence the growth of the aquatic plant, water hyacinth.
