Abstract Oxidation of ammonia to nitrite by bacteria and archaea is responsible for global emissions nitrous oxide directly indirectly through provision and, after further oxidation, nitrate denitrifiers. Their contributions increasing N 2 O are greatest in terrestrial environments, due the dramatic continuing increases use ammonia‐based fertilizers, which have been driven requirement increased food production, but also provide a source energy oxidizers (AO), leading an imbalance nitrogen cycle. Direct production AO results from several metabolic processes, sometimes combined with abiotic reactions. Physiological characteristics, including mechanisms vary within between ammonia‐oxidizing (AOA) (AOB) comammox yield AOB higher than other two groups. There strong evidence niche differentiation AOA respect environmental conditions natural engineered environments. In particular, favored low soil pH are, respectively, rates ammonium supply, equivalent application slow‐release fertilizer, or high addition concentrations inorganic urea. These differences potential better fertilization strategies that could both increase fertilizer efficiency reduce agricultural soils. This article reviews research on biochemistry, physiology ecology discusses consequences communities subjected different practices ways this knowledge, coupled improved methods characterizing communities, might lead mitigation emissions.

Complete nitrification: insights into the ecophysiology of comammox Nitrospira

Applied Microbiology and Biotechnology, Год журнала: 2018, Номер 103(1), С. 177 - 189

Nitrification, the oxidation of ammonia via nitrite to nitrate, has been considered be a stepwise process mediated by two distinct functional groups microorganisms. The identification complete nitrifying Nitrospira challenged not only paradigm labor division in nitrification, it also raises fundamental questions regarding environmental distribution, diversity, and ecological significance nitrifiers compared canonical Recent genomic physiological surveys identified factors controlling their ecology niche specialization, which thus potentially regulate abundances population dynamics different guilds. This review summarizes recently obtained insights into metabolic differences known discusses these light potential adaptation differentiation between nitrifiers.

Ammonia oxidation is a fundamental core process in the global biogeochemical nitrogen cycle. Oxidation of ammonia (NH3) to nitrite (NO2 -) first and rate-limiting step nitrification carried out by distinct groups microorganisms. essential for nutrient turnover most terrestrial, aquatic engineered ecosystems plays major role, both directly indirectly, greenhouse gas production environmental damage. Although has been studied over century, this research field galvanised past decade surprising discoveries novel oxidising This review reflects on date discusses gaps remaining our knowledge biology oxidation.
