“…In agreement with findings from other waste composting studies (Ren et al, 2018; Yamamoto et al, 2010, 2011; Yan et al, 2018; Zeng et al, 2011), AOA gene copy numbers were higher (by approx. one order of magnitude) than those found for AOB.…”

“…It is thought that AOA have a higher temperature optimum than AOB (Nozhevnikova et al, 2019), and may gain a competitive advantage over AOB in high temperature, low oxygen environments, such as the thermophilic stage of composting (Ren et al, 2018). It is also clear from our results that the addition of GW during composting increased the numbers of AOB and AOA gene copies present, which may indicate enhanced potential for nitrification (Cáceres et al, 2018; Yan et al, 2018).…”

“…Unlike AOB, however, there was little variation in AOA gene copy numbers over time, with most staying steady. Other studies have noted higher AOA gene levels in compost, with animal manure composts exhibiting log 7–8 AOA gene copies g −1 in the later stages of composting (Yamamoto et al, 2010), agricultural waste composts showing log 10–11 AOA gene copies g -1 steadily throughout composting (Zeng et al, 2011), and studies of agricultural wastes and manure composts also showing a steady level of log 8–9 AOA gene copies g −1 during composting (Ren et al, 2018; Yan et al, 2018). The nature of the non-source-separated residual BMW used in the present study may have led to lower AOA gene copy numbers than those seen in agricultural or manure waste composts, but the steady levels of AOA observed over composting time are in agreement with findings from the literature.…”

“…The rate-limiting step in nitrification is the oxidation of ammonia to nitrite, known as ammonia-oxidation. This step can be performed by both ammonia-oxidising bacteria (AOB) and ammonia-oxidising archaea (AOB), and genes from both have been detected in waste composting (Ren et al, 2018; Yamamoto et al, 2010, 2011; Yan et al, 2018; Zeng et al, 2011). Levels of AOB and AOA genes have been found to correlate with potential ammonia oxidation in agricultural waste and animal manure composts (Yan et al, 2018; Zeng et al, 2011), indicating that measurement of gene copy numbers can be a useful indicator of this crucial N-cycling step.…”

Effect of green waste and lime amendments on biostabilisation, physical-chemical and microbial properties of the composted fine fraction of residual municipal solid waste

Implementation of guidelines to reduce the amount of biodegradable municipal waste (BMW) sent to landfill has created a need in the waste-management industry to investigate possible methods of accelerating biostabilisation of residual BMW. The effect of commercially feasible manipulations (lime and green waste (GW)) on the rate of biostabilisation of the fine (<20 mm) fraction of residual BMW was investigated. The physical and chemical attributes of the composted wastes were measured, and their bacterial communities profiled using traditional culture-based methods. In addition, ammonia-oxidising microbes were monitored during the biostabilisation process using molecular profiling methods. Addition of GW accelerated biostabilisation, reduced conductivity and increased the levels of ammonia-oxidising bacterial (AOB) and archaeal (AOA) genes. The best stability was noted in the dual (Lime + GW) treatment, which was under the limit of 13 mmol O2 kg DM−1 h−1 recommended by the Irish compost standard. Biostabilised wastes met recommendations for source-segregated compost for pH (6-8) and pathogens ( E. coli and Salmonella), but not heavy metals, indicating their unsuitability for uses other than landfill cover. Levels of AOA genes (log 3–6 g−1 DM) were higher than AOB (log 1–6 g−1 DM, indicating AOA may contribute more to potential ammonia oxidation in residual BMW composting.

“…Considering the consequential decrease of pH in the bioavailability of N, acidic environments can encourage AOA growth over AOB because of their significant correlation with ammonia (Li et al, 2015a;Ramanathan et al, 2017). Various results of the comparative abundance of AOB and AOA have been reported in the context of sediments (Kataoka et al, 2018;Yan et al, 2018).…”

Ammonia-oxidizing communities play important functional roles in the nitrification. However, environmental stresses can significantly affect this process by controlling the abundant communities of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) communities. In this study, we examined the abundance variations of ammonia-oxidizing communities using quantitative polymerase chain reaction (qPCR) and terminal-restriction fragment length polymorphism (T-RFLP) in a typical subtropical river, Luotian County, South Dabie Mountains, China. Clone libraries were conducted to evaluate the community structure and abundance of AOA and AOB in sediments. Results showed that Nitrososphaera sp and Nitrosopumilus sp were the most dominant AOA. The abundance of the AOA and AOB amoA gene ranged from 5.28 × 108 gene copies (g-soil−1) to 2.23 × 108 gene copies (g-soil−1) and 5.45 × 108 gene copies (g-soil−1) to 3.30 × 107 gene copies (g-soil−1), respectively. Five environmental variables, namely, ORP, DO, NO${}_{3}^{-}$, Temp, and NH${}_{4}^{+}$ were played a major function in microbial communities of AOA and AOB in sediments. The T-RFLP profiles of AOA showed that 488 and 116 bp T-RFs were dominated. Overall, the results of this study showed that anthropogenic activities andenvironmental stress in rivers can alter the structure and function of microbes in their variable environment.
