“…strain JR1 [27] can grow in the higher range for nitrogen reduction. Most strains are more suitable for denitrification reactions in neutral to alkaline environments [28,29]. In this study, pH values were set to 4.5, 6.0, 7.5, and 9.0 to analyze the effect of different pH values on the different nitrification capacities of strain Ab03.…”

An efficient ammonia nitrogen degrading bacterial strain was isolated from a fish and shrimp pond and identified as Bacillus subtilis (Ab03). Firstly, the strain was continuously domesticated in ammonium solution to improve its nitrogen removal capacity. The performance of the strain in terms of nitrogen removal efficiency under different culture conditions was then examined. Finally, the nitrogen removal process and related strain mechanisms were analyzed by nitrogen balance. The results showed the strain Ab03 could remove 91.67% of NH 4 + -N at 300 mg/L under the conditions of glucose as the single carbon source, C/N of 15, pH of 7.5, the temperature of 35 ℃ and dissolved oxygen of 7-8 mg/L. It was also found that under conditions where ammonia nitrogen was the only nitrogen source, strain Ab03 could also undergo aerobic denitrification for simultaneous conversion, with a final gas conversion rate of 74.81%.

“…The Mn(II) removal efficiency was at its maximum at 150 rpm and then decreased when the rotating speed was higher than 150 rpm. This might be because the growth of bacteria and the capability to remove the contaminant were inhibited when the content of oxygen exceeded a critical level ( Lei et al, 2019 ; Hou et al, 2021 ; Huang et al, 2021 ). Overall, strain QZB-1 showed a high tolerance against to Mn(II) (up to 364 mM) and could efficiently remove 18 mM of Mn(II) under the following conditions: pH 5.5, 35°C, and 150 rpm.…”

Manganese (Mn(II)) pollution has recently increased and requires efficient remediation. In this study, Serratia marcescens QZB-1, isolated from acidic red soil, exhibited high tolerance against Mn(II) (up to 364 mM). Strain QZB-1 removed a total of 98.4% of 18 mM Mn(II), with an adsorption rate of 71.4% and oxidation rate of 28.6% after incubation for 48 h. The strain synthesized more protein (PN) to absorb Mn(II) when stimulated with Mn(II). The pH value of the cultural medium continuously increased during the Mn(II) removal process. The product crystal composition (mainly MnO2 and MnCO3), Mn-O functional group, and element-level fluctuations confirmed Mn oxidation. Overall, strain QZB-1 efficiently removed high concentration of Mn(II) mainly via adsorption and showed great potential for manganese wastewater removal.

“…Most HNADs are more adapted to neutral-to-alkaline environments (pH 6.0-9.0), and the optimal pH range for nitrogen removal is 7.0-8.0 (Table 6) (Chen et al, 2014;Liu et al, 2016;Hou et al, 2021). Some bacteria such as Acinetobacter sp.…”

With the increasing use of animal and plant proteins, pollution due to nitrogen sources is attracting increasing attention. In particular, the amount of nitrogen-containing sewage discharged into the environment has increased significantly, causing eutrophication of water bodies and environmental degradation of water quality. Traditionally, nitrifying bacteria perform ammonia nitrification under aerobic conditions, while denitrifying bacteria perform nitrate/nitrite denitrification under anaerobic conditions. However, heterotrophic nitrifying and aerobic denitrifying microorganisms (HNADs) perform ammonia nitrification and nitrate/nitrite denitrification under the same aerobic conditions using an organic carbon source, which is a much simpler and more efficient process. In this review, the distribution and evolutionary relationships of novel HNADs strains are presented, and the influencing factors, metabolic pathways, key enzymes, and practical applications of HNADs are reviewed.
