“…Similar observations were made by Guo et al (2016) who reported an increase in growth and denitrification up to C/N ratio of 13 and a decline above C/N ratio of 13. Huang et al (2017) also reported a similar trend of total nitrogen removal by Serratia marcescens. C/N ratio as high as 12 for Providencia rettgeri (Ye et al 2016), 15 for Bacillus sp., and 16 for Pseudomonas stutzeri AD-1 (Zhao et al 2010;Qing et al 2018) have been reported previously.…”

Denitrification is a potential strategy for nitrate removal from wastewater. This study reports the isolation of a novel bacterium Georgenia daeguensis ARB2 which has not been earlier reported for treatment of wastewater. ARB2 was isolated from pharmaceutical wastewater and optimized for growth and nitrate removal under conditions of 10 mM nitrate stress (140 mgL −1 NO − 3 − N ). It can utilize nitrate as a sole source of nitrogen, exhibits highest growth and aerobic denitrification using glycogen + maltose as a carbon source at pH 7.0, carbon-to-nitrogen ratio of 34, temperature 30 °C, and shaking speed of 100 rpm. ARB2 removes 20% of the initial nitrate concentration of 10 mM in 56 h, and 40% of the initial nitrate concentration of 1 mM in 52 h. Further, the efficacy of strain ARB2 was tested on real contaminated waters and was found to successfully reduce nitrate levels in them. The findings suggest that Georgenia daeguensis ARB2 has a potential application for the alleviation of nitrate under aerobic conditions.

“…The process becomes more economically favourable as there is less chemical requirement for adjusting the pH as the alkalinity generated during denitrification is able to make up for the alkalinity consumption during the nitrification process (Huang and Tseng ). Keeping in mind the advantages offered by these micro‐organisms, various studies have been carried out which have successfully isolated heterotrophic aerobic bacteria capable of performing simultaneous nitrification and aerobic denitrification (Huang et al ).…”

“…Various carbon sources such as glycerol, glucose, succinate, ethanol, sucrose, methanol, formate, and sodium pyruvate have been tested for their effect on denitrification rate by various micro‐organisms. To carry out simultaneous nitrification and aerobic denitrification, glucose is the best recommended carbon source for Anoxybacillus contaminans, Enterobacter cloacae, Serratia marcescens and Bacillus cereus (Chen et al ; Guo et al ; Huang et al ; Barman et al ). Huang et al () reported 78·86% of nitrate removal in 72 h with sodium acetate for Zoogloea .…”

Role of heterotrophic aerobic denitrifying bacteria in nitrate removal from wastewater

With the increase in industrial and agricultural activities, a large amount of nitrogenous compounds are released into the environment, leading to nitrate pollution. The perilous effects of nitrate present in the environment pose a major threat to human and animal health. Bioremediation provides a costeffective and environmental friendly method to deal with this problem. The process of aerobic denitrification can reduce nitrate compounds to harmless dinitrogen gas. This review provides a brief view of the exhaustive role played by aerobic denitrifiers for tackling nitrate pollution under different ecological niches and their dependency on various environmental parameters. It also provides an understanding of the enzymes involved in aerobic denitrification. The role of aerobic denitrification to solve the issues faced by the conventional method (aerobic nitrification-anaerobic denitrification) in treating nitrogenpolluted wastewaters is elaborated. verts the iron centre of haemoglobin from Fe 2+ to Fe 3+ Role of heterotrophic aerobic denitrifying bacteriaA.

“…However, various heterotrophic bacteria capable of both aerobic denitrification and heterotrophic nitrification had been identified by several researchers (Huang et al . 2017). As described in the previous sections, this excludes the need of an additional anaerobic compartment and the possibility of simultaneous nitrification–denitrification within the single system.…”

One of the major challenges in any sustainable aquaculture production systems is the accumulation of nitrogenous waste such as ammonia and its biological nitrification products viz nitrite and nitrate. Considering the bio-security issues, amelioration of these wastes without water exchange can be accomplished only by way of establishing in situ nitrification and denitrification through biofilters/ bioreactors activated with nitrifying/denitrifying bioaugmentors. In such systems, coexistence of aerobic denitrifiers, anaerobic ammonia oxidizers (Anammox) and complete ammonia oxidizers (Comammox) together with the autotrophic nitrifiers enhance the coupled nitrification-denitrification. This promotes total nitrogen removal without external carbon supplements or additional anerobic compartment in the system. Various recirculating aquaculture systems (RAS) comprise diverse nitrifying community in biofilters/bioreactors thereby imparting distinctive nitrogen conversion in the system. Meanwhile, the structure and population dynamics of the nitrifying/denitrifying consortia are influenced by the environmental factors forming the decisive factors of the success of the processes. Accordingly, understanding the complexity of nitrifying/denitrifying community composition turns out to be a requirement to facilitate its improvised performance. In this context, the review addresses different biological nitrogen removal systems, significance of nitrification-denitrification in RAS, genetic diversity of the key players in RAS, methods of analysis of their community structure, current application and prospects of the processes in RAS.
