Summary: The study found that abundance of AOB and AOA increased under organic N conditions, and different short-term organic manure N input treatments altered the diversity of soil AOB and AOA communities. Soil microbial community and specific N-utilizing microbial groups were significantly affected by practices of organic manure N input.

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: 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 effects of nitrogen (N) fertilization on soil microorganisms in a temperate forest dominated by Quercus crispula were investigated. The results showed that N loading increased total carbon (C) concentration and bacterial biomass in the organic layers, while fungal biomass decreased in the mineral soils. These changes may be attributed to the accumulation of recalcitrant C and decreased investment in symbionts by underground plants. These findings contribute to a better understanding of belowground C dynamics.

Summary: The study found that ammonia-oxidizing archaea and ammonia-oxidizing bacteria had significantly higher transcriptional abundance of amoA gene in soils compared to complete ammonia oxidizers, suggesting the former may be the dominant contributors to soil nitrification. Seasonal variation and fertilization regimes substantially affected the abundance of ammonia-oxidizing microbes, with ammonia-oxidizing bacteria being less sensitive to these factors compared to ammonia-oxidizing archaea.

Summary: The discovery of complete ammonia oxidizers has revolutionized our understanding of two-step nitrification. Previous studies have suggested that these organisms may outcompete canonical ammonia oxidizers under ammonia-limited conditions. However, there is currently no convincing evidence linking their activity to nitrification in acidic soils.

Summary: The coexistence of antibiotics and heavy metals in soil has negative effects on microorganisms, but their impact on functional microorganisms related to nitrogen cycle is unclear. A study was conducted to investigate the effects of sulfamethazine (SMT) and cadmium (Cd) on potential nitrification rates (PNR) and ammonia oxidizers (AOA and AOB). The results showed that PNR initially decreased and then increased over time in Cd- or SMT-treated soil. The addition of SMT improved AOA activity, while Cd inhibited both AOA and AOB. Combined SMT and Cd addition had a higher relative abundance of AOA and AOB compared to single Cd addition.

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: Replacing 30%-70% of mineral nitrogen with organic nitrogen can significantly increase the potential nitrification rate in soil, affecting the abundance and community structure of both AOA and AOB. The contribution of AOB to the nitrification process in paddy soils exceeds that of AOA.

Summary: Fertilization and soil environmental factors play a role in the niche differentiation of ammonia-oxidizing microorganisms and affect the ammonia-oxidation process. In this study, the effect of manure, chemical fertilizer, and manure combined with biochar on soil properties and the abundance, diversity, and structure of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) in the rhizosphere were investigated. The results showed that chemical fertilizer and manure combined with biochar increased the potential nitrification rate (PNR) and AOA amoA gene abundance, while manure combined with biochar decreased PNR and AOA amoA gene abundance. The population structure of AOA and AOB was influenced by pH, available phosphorus, carbon-to-nitrogen ratio, soil moisture content, nitrate nitrogen, and ammonium nitrogen in the rhizosphere. The ammonia oxidation process in the acid purple soil was dominated by AOA in the presence of chemical fertilizer and pig manure combined with rice husk biochar.

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: 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.

The addition of exogenous functional microbial consortium and glomalin-related soil protein (GRSP) can promote the degradation of bound PAH residues. This study fills the cognitive gap of GRSP in regulating the degradation of bound PAH residues in soil.

Summary: This study assessed the impact of conservation agriculture on the biological soil health index in a rice-wheat system in the Indo-Gangetic Plains. The results showed that zero till direct seeded rice and crop residue incorporation could improve soil organic carbon, enzyme activities, and microbial population. Specifically, the inclusion of mungbean residues and sesbania brown manuring significantly increased the abundance of the nifH gene in the soil.

Summary: Integrating diverse cover crops into dryland crop-fallow rotations can enhance soil nutrient and water retention, suppress soil-borne pests, and improve soil health. The effects on soil nematode communities are modulated by the functional type and mixture composition of the cover crops. Selecting cover crops with appropriate traits can improve soil health through suppression of plant-parasitic nematodes, promotion of free-living nematodes, and enhancement of soil food web complexity.

Summary: In extreme desert environments, black septate endophytes (DSE) can benefit the relict plant Gymnocarpos przewalskii by assisting it to survive and maintain ecosystem stability. The colonization of DSE in the roots of G. przewalskii varies significantly with seasons and sites, with soil properties being a major factor affecting the composition of DSE. Additionally, the functional metabolite composition of DSE strains varies greatly with different drought levels and isolates, indicating the potential complementarity between different strains in helping hosts cope with drought stress.
