Controls and Adaptive Management of Nitrification in Agricultural Soils

Agriculture is responsible for over half of the input reactive nitrogen (N) to terrestrial systems; however improving N availability remains primary management technique increase crop yields in most regions. In majority agricultural soils, ammonium rapidly converted nitrate by nitrification, which increases mobility through soil matrix, strongly influencing retention system. Decreasing nitrification desirable decrease losses and fertilizer use efficiency. We review controlling factors on rate extent soils from temperate regions including substrate supply, environmental conditions, abundance diversity nitrifiers plant microbial interactions with nitrifiers. Approaches include those that control inhibit directly. Strategies timing fertilization coincide rapid update, formulation fertilizers slow release or inhibitors, keeping growing continuously assimilate N, increasing assimilation (immobilization). Another effective strategy directly either synthetic biological inhibitors. Commercial inhibitors are but their complicated a changing climate organic requirements. The nitrifying organisms plants microbes producing promising approach just beginning be critically examined. Climate smart agriculture will need carefully consider optimized seasonal these strategies remain tools.

Ecology of Nitrogen Fixing, Nitrifying, and Denitrifying Microorganisms in Tropical Forest Soils

Frontiers in Microbiology, Год журнала: 2016, Номер 7

Опубликована: Июль 5, 2016

Soil microorganisms play important roles in nitrogen cycling within forest ecosystems. Current research has revealed that a wider variety of microorganisms, with unexpected diversity their functions and phylogenies, are involved the cycle than previously thought, including nitrogen-fixing bacteria, ammonia-oxidizing bacteria archaea, heterotrophic nitrifying anammox as well denitrifying archaea fungi. However, vast majority this been focused temperate regions, relatively little is known regarding ecology nitrogen-cycling tropical subtropical Tropical forests characterized by high precipitation, low annual temperature fluctuation, heterogeneity plant diversity, large amounts litter, unique soil chemistry. For these reasons, regulation may be very different from This great importance because growing concerns effect land use change chronic-elevated deposition on processes forests. In context global change, it crucial to understand how environmental factors changes ecosystems influence composition, abundance activity key players cycle. review, we synthesize limited currently available information microbial communities fixation, nitrification denitrification, provide deeper insight into mechanisms regulating We also highlight gaps our understanding microbially mediated soils identify areas for future research.

Cultivation and characterization of Candidatus Nitrosocosmicus exaquare, an ammonia-oxidizing archaeon from a municipal wastewater treatment system

The ISME Journal, Год журнала: 2017, Номер 11(5), С. 1142 - 1157

Опубликована: Фев. 14, 2017

Thaumarchaeota have been detected in several industrial and municipal wastewater treatment plants (WWTPs), despite the fact that ammonia-oxidizing archaea (AOA) are thought to be adapted low ammonia environments. However, activity, physiology metabolism of WWTP-associated AOA remain poorly understood. We report cultivation complete genome sequence Candidatus Nitrosocosmicus exaquare, a novel representative from WWTP Guelph, Ontario (Canada). In enrichment culture, Ca. N. exaquare oxidizes nitrite stoichiometrically, is mesophilic, tolerates at least 15 mm ammonium chloride or sodium nitrite. Microautoradiography (MAR) for cultures demonstrates assimilates bicarbonate association with oxidation. using inorganic carbon, activity greatly stimulated culture by addition organic compounds, especially malate succinate. cells coccoid diameter ~1-2 μm. Phylogenetically, belongs Nitrososphaera sister cluster within Group I.1b Thaumarchaeota, lineage which includes most other reported sequences WWTPs. The 2.99 Mbp encodes pathways oxidation, fixation, urea transport breakdown. addition, this key genes dealing oxidative stress, including peroxidase catalase. Incubations biofilm demonstrate partial inhibition 2-phenyl-4,4,5,5-tetramethylimidazoline-1-oxyl 3-oxide (PTIO), suggesting exaquare-like may contribute nitrification situ. CARD-FISH-MAR showed no incorporation Thaumarchaeaota, incorporate non-bicarbonate carbon sources rely on an alternative yet unknown metabolism.
