“…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 .…”

“…The specific enzyme activity of Nar in this strain was found to be higher than that observed in Klebsiella pneumoniae (Padhi et al ). Bacillus cereus possesses nitrite reductase enzyme which is symbolic of the aerobic denitrification process (Barman et al ). Song et al () amplified nitrite reductase from Bacillus confirming the presence of the Nir genes, responsible for aerobic denitrification ability of the strain.…”

Role of heterotrophic aerobic denitrifying bacteria in nitrate removal from wastewater

et al. 2020

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.

“…The nitrite issue is particularly serious in the aquaculture industry. The application of the intensive culture system improves the aquatic products’ yields, however, at the same time, excess nitrite was easily accumulated by uneaten high protein feed and feces under nitrogen cycle in such recirculating aquaculture system (Barman et al, 2017). Nitrite poses a severe threat to aquatic animals, and further to humans, by triggering a series of negative physiological effects, resulting in illness or even death (Tseng and Chen, 2004; He et al, 2017).…”

“…Since the existence of aerobic denitrification was confirmed in Paracoccus denitrificans (formerly Thiosphaera pantotropha ) (Robertson and Kuenen, 1984), numerous aerobic denitrifying bacteria belonging to species of Alcaligenes (Vanniel et al, 1992; Matsuzaka et al, 2003), Diaphorobacter (Khardenavis et al, 2007), Pseudomonas (Wan et al, 2011; Zhang et al, 2011; Qiu et al, 2012; Zheng et al, 2014; Zhou et al, 2014; Huang et al, 2015; Zhao et al, 2018), Acinetobacter (Ren et al, 2014; Liu et al, 2015; Yang et al, 2016), Bacillus (Zhang et al, 2010; Song et al, 2011; Barman et al, 2017), Marinobacter (Zheng et al, 2012), and Paracoccus (Shi et al, 2013) have been isolated. Nevertheless, among these reports about aerobic denitrifiers, only a few are focused on utilizing nitrite as the only nitrogen source and removing nitrite of low concentrations, especially in aquaculture water, thus it is very urgent to explore more aerobic denitrifying bacteria that utilize and remove low-concentration nitrite from water with high efficiency.…”

Nitrite in a water environment is very harmful to humans and aquatic animals. A novel aerobic denitrifying bacterium able to utilize NO2--N as the only nitrogen source was isolated for the purpose of removing nitrite from water, which was identified as Acinetobacter sp. and named as YT03. The growth and denitrification activity of strain YT03 was assessed comprehensively. Results showed that the nitrite in water with an initial concentration of 10 mg L–1 could be completely removed within 6 h by strain YT03, and the optimal conditions for strain YT03 to remove nitrite were as follows: sodium succinate as the carbon source, C/N ratio of 16, pH of 6.5, temperature of 30°C, and shaking speed of 250 rpm. An RNA-Seq transcriptome analysis was used to find genes associated with nitrite removal. Compared with the removal of ammonia nitrogen, 47 genes were significantly differentially expressed, including 20 up-regulated and 27 down-regulated genes, mainly involved in the transport process, biosynthetic process, and so on. And among the differentially expressed genes, C4-dicarboxylate transporter (DctA) and nitrate/nitrite transporter (Nrt) might be of importance for the efficient utilization of carbon and nitrogen sources in aerobic nitrite denitrification with sodium succinate by strain YT03.
