Summary: This study found significant shifts in potential ammonia oxidation rates (PARs) and gene abundances of ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA) along different salinity gradients. The PARs were higher under high salinity conditions, and the AOB gene abundance was greater than AOA under moderate and high salinity. This has important implications for nitrogen cycling in estuarine sediments.

Summary: Intercropping has a significant impact on soil properties and microbial communities, with different intercropping systems affecting ammonia-oxidizing microorganisms differently in different seasons. Soil physicochemical state, PNR, AOA and AOB communities were significantly altered by intercropping, with seasonal variation playing a greater role in shaping the community structures.

Summary: Archaeal membrane lipids, specifically the GDGTs, can be used to reconstruct ancient temperatures and provide insights into the ecology and evolution of marine ammonia-oxidizing archaea (AOA). The study identified thermal and nonthermal behaviors of GDGTs, which can be used as indicators of environmental temperature. The distribution of GDGTs in AOA cultures and shallow water samples followed a temperature-dependent trend, while deep water samples showed a nonthermal behavior. Statistical analysis revealed long-term trends in GDGT-2/GDGT-3 ratios, suggesting a suppression of deep water marine AOA during greenhouse climates in the Mesozoic and early Cenozoic periods.

Summary: This study comprehensively investigated the impacts of ammonia and salinity on culturing nitrifying microorganisms and successfully formulated nitrifying cultures for different recirculating aquaculture system (RAS) types. The findings suggest that cultures prepared at low ammonia loading rates are most suitable for various RAS types, while cultures prepared at high ammonia loading rates are dominated by nitrifying microorganisms with low substrate affinity.

Summary: This study analyzed activated sludge samples from municipal and industrial wastewater treatment plants and found that comammox bacteria were more abundant than ammonia-oxidizing bacteria and ammonia-oxidizing archaea in municipal plants, while this trend did not hold true for industrial plants. Furthermore, a higher diversity of comammox bacteria was found in municipal samples. This study provides important insights into the abundance and diversity of comammox bacteria in municipal and refinery wastewater treatment systems.

Summary: The study found that ammonia-oxidizing archaea are more abundant in systems with low ammonium availabilities, while ammonia-oxidizing bacteria are more abundant when ammonium availability increases. Population dynamics of ammonia oxidizers may shift in response to changes in ammonium concentrations.

Summary: The meta-analysis of laboratory incubation studies with 1-octyne as the nitrification inhibitor shows that AOB play a more dominant role in soil nitrification in cropland than in wetland soils, indicating a major role of AOB in acidic soil nitrification. Moreover, the reduction of nitrification rate by 1-octyne is greater in soils incubated in slurry and with nitrogen additions, suggesting AOB's importance in nitrification in global acidic soils.

Summary: This study investigated the impacts of elevated CO2 and cadmium levels on soil nitrification in the rhizosphere of Robinia pseudoacacia L. seedlings. The results showed that elevated CO2 combined with Cd pollution generally stimulated nitrification enzyme activities and influenced bacterial community structures.

Summary: The importance and diversity of archaea in aquaculture are often overlooked. Recent research has revealed the widespread presence of archaea in various aquaculture systems, where they play key roles in nitrogen cycling, sulfur cycling, and nutrition. Despite limitations and a lack of comprehensive information, archaea have great potential and future prospects in aquaculture.

Summary: Plantations of saline-alkali tolerant rice in coastal areas are proposed to improve rice yield and ensure food security. This study investigated the effects of saline-alkali tolerant rice cultivation on the nitrification process in coastal solonchaks. The results showed that the abundance and nitrification rates of AOA and AOB decreased with increasing salinity, but increased significantly in the rice rhizosphere. Saline-alkali tolerant rice cultivation enhanced the nitrification process of the soil by increasing the nitrification contribution of AOB.

Summary: The discovery of ammonia-oxidizing archaea (AOA) and complete ammonia-oxidizing (comammox) bacteria in terrestrial ecosystems highlights their important role in nitrification. A nutrient-limited enrichment strategy was found to favor the growth of comammox bacteria with high affinity and yield. Direct enrichment from soil and nutrient-limited sub-cultivation consistently yielded high enrichments of Nitrosocosmicus-affiliated AOA associated with multiple canonical nitrite-oxidizing Nitrospira strains.

Summary: This study highlights the important role of local ammonium concentration in affecting the ecological niche differentiation of comammox and canonical ammonia-oxidizing prokaryotes. The results show growth differences between CAOB and AOA, with CAOB favoring oligotrophic environments and being more tolerant to a broader range of ammonium concentrations.

Summary: Using metagenomics, we characterized and compared the ammonia-oxidizing archaea (AOA) community in three estuaries of China. We identified five major AOA groups and found that their diversity and distribution were influenced by spatial and environmental factors. Estuarine AOA encoded more genes involved in glucose and amino acid metabolism, transport systems, osmotic control, and cell motility compared to those in terrestrial and marine habitats. Our findings highlighted the potential adaptation strategies of estuarine AOA and their importance in the nitrogen and carbon cycles.

Summary: This study identified an ammonia-tolerant archaea species Candidatus Nitrosocosmicus agrestis from agricultural soil, which can tolerate high concentrations of ammonia. Through genome analysis and gene expression studies, production and excretion of polyamines were proposed as one of the reasons for its ammonia tolerance.

Summary: Plant growth regulators (PGRs) are often overestimated in their ability to improve plants' tolerance to heavy metals due to the neglect of native rhizobacteria's contribution. In this study, it was found that native rhizobacteria can cooperate with PGRs to enhance the tolerance of duckweed Spirodela polyrhiza to Cd stress. The synergistic effects of bacterial isolates and salicylic acid improved Cd tolerance, indicating that active rhizobacteria are not necessarily plant growth-promoting rhizobacteria (PGPRs). Physiological and transcriptomic analyses revealed that the cooperation between the native bacterium Pseudomonas and salicylic acid can reduce Cd accumulation, decrease oxidative stress, and induce the synthesis of flavonoids in duckweed. Therefore, the contribution of native rhizobacteria should be considered when applying PGRs to improve plant tolerance to heavy metals.

Summary: Recent research suggests that some species from the Nitrosocosmicus clade of ammonia-oxidizing archaea (AOA) may have ammonium tolerance similar to many ammonia-oxidizing bacteria (AOB) species. The growth of Nitrosocosmicus clade and its contribution to N2O production in agricultural soil under high ammonium inputs were investigated.
