Anaerobic ammonium oxidation (anammox) has been proven to be an important nitrogen removal process in terrestrial ecosystems, particularly paddy soils. However, the contribution of anammox in acidic red soils to nitrogen loss has not been well-documented to date. Here, we investigated the activity, abundance, and distribution of anammox bacteria in red soils collected from nine provinces of Southern China. High-throughput sequencing analysis showed that Candidatus Brocadia dominates the anammox bacterial community (93.03% of sequence reads). Quantification of the hydrazine synthase gene (hzsB) and anammox 16S rRNA gene indicated that the abundance of anammox bacteria ranged from 6.20 × 106 to 1.81 × 109 and 4.81 × 106 to 4.54 × 108 copies per gram of dry weight, respectively. Contributions to nitrogen removal by anammox were measured by a 15N isotope-pairing assay. Anammox rates in red soil ranged from 0.01 to 0.59 nmol N g−1 h−1, contributing 16.67–53.27% to N2 production in the studied area, and the total amount of removed nitrogen by anammox was estimated at 2.33 Tg N per year in the natural red soils of southern China. Pearson correlation analyses revealed that the distribution of anammox bacteria significantly correlated with the concentration of nitrate and pH, whereas the abundance and activity of anammox bacteria were significantly influenced by the nitrate and total nitrogen concentrations. Our findings demonstrate that Candidatus Brocadia dominates anammox bacterial communities in acidic red soils and plays an important role in nitrogen loss of the red soil in Southern China.

“…Anaerobic ammonia oxidizing (Anammox) bacteria (AnAOB) grow autotrophically on ammonia and nitrite under oxygen deplete conditions, which gives them a unique ecological niche. As a result, AnAOB are widely distributed in suboxic environments throughout the world, including marine, freshwater, terrestrial, and various extreme environments [1,2]. In fact, it is estimated that Anammox is responsible for~30% of global oceanic nitrogen loss [3].…”

“…AOA also have a more efficient pathway for carbon fixation than do the AOB, contributing to better growth on limited substrate [12]. Similarly, affinity plays a role in niche differentiation of AnAOB species, where it has been suggested that members of the Brocadia clade are copiotrophic and dominate under nutrient replete conditions whereas members of the Kuenenia clade have more oligotrophic characteristics [1,13]. Finally, affinity plays a role in cooperation (passing of nitrite) and competition (for ammonia) between AOA or AOB and AnAOB.…”

Anaerobic ammonia-oxidizing (Anammox) bacteria (AnAOB) rely on nitrite supplied by ammonia-oxidizing bacteria (AOB) and archaea (AOA). Affinities for ammonia and oxygen play a crucial role in AOA/AOB competition and their association with AnAOB. In this work we measured the affinity constants for ammonia and oxygen (half-saturation; k m) of two freshwater AOA enrichments, an AOA soil isolate (N. viennensis), and a freshwater AnAOB enrichment. The AOA enrichments had similar kinetics (μ max ≈ 0.36 d −1 , k m,NH4 ≈ 0.78 µM, and k m,O2 ≈ 2.9 µM), whereas N. viennensis had similar k m values but lower μ max (0.23 d −1). In agreement with the current paradigm, these AOA strains showed a higher affinity for ammonia (lower k m,NH4 ; 0.34-1.27 µM) than published AOB measurements (>20 µM). The slower growing AnAOB (μ max ≈ 0.16 d −1) had much higher k m values (k m,NH4 ≈ 132 µM, k m,NO2 ≈ 48 µM) and were inhibited by oxygen at low levels (halfoxygen inhibition; k i,O2 ≈ 0.092 µM). The higher affinity of AOA for ammonia relative to AnAOB, suggests AOA/AnAOB cooperation is only possible where AOA do not outcompete AnAOB for ammonia. Using a biofilm model, we show that environments of ammonia/oxygen counter diffusion, such as stratified lakes, favors this cooperation.

<p>This review shows regards of the recently experienced concerning the environments of ammonia oxidizing bacteria (AOB), ammonia oxidizing archaea (AOA) microorganisms, and denitrifying microbes. The advancements of molecular biology techniques have encouraged staggeringly to the fast recent developments in the sector. Various methods for implementing so are discussed. The function of AOB, AOA, and denitrifying microorganism composition was investigated through a high throughput of the 16S rRNA amplicon sequencing protocol. There is potential to observe the specific species appearance of these microorganisms in each environment and get to the evaluated relative abundance of several kinds. There is information indicated which the structure of denitrifying and nitrifying group was monitored field to significant fluctuations and the complexes, together in space and in time. More effort is required to enhance and isolate those microorganisms that common of the progressions and to function them through the compound of molecular techniques, biochemical and physiological. However, the investigation with deoxyribonucleic acid (DNA), antibodies, and the polymerase chain reaction (PCR) was preferred mainly to report the composition of chemolithoautotrophic bacteria, surveys of their characteristics in environmental that needed quantification at the transcriptional level is presently not available.</p>
