Dissimilatory nitrogen reduction in intertidal sediments of a temperate estuary: small scale heterogeneity and novel nitrate-to-ammonium reducers. [PDF]

open access: yesFrontiers in Microbiology, 2015
The estuarine nitrogen cycle can be substantially altered due to anthropogenic activities resulting in increased amounts of inorganic nitrogen (mainly nitrate).

Microbiological Nitrogen Transformations in Soil Treated with Pesticides and Their Impact on Soil Greenhouse Gas Emissions

open access: yesAgriculture, 2021
Research was conducted in connection with the pressure exerted by man on the environment through the use of pesticides. The aim of the study was to assess the impact of pesticides on soil and to evaluate the effect of these changes on greenhouse gas ...

Resource Concentration Modulates the Fate of Dissimilated Nitrogen in a Dual-Pathway Actinobacterium

open access: yesFrontiers in Microbiology, 2019
Respiratory ammonification and denitrification are two evolutionarily unrelated dissimilatory nitrogen (N) processes central to the global N cycle, the activity of which is thought to be controlled by carbon (C) to nitrate (NO3−) ratio. Here we find that

Assessment of the Effects of Soil Fertilization with Spent Mushroom Substrate in the Context of Microbial Nitrogen Transformations and the Potential Risk of Exacerbating the Greenhouse Effect

open access: yesAgriculture, 2022
The intensification of agriculture leads to worrying changes in agro-ecosystems. Research has been conducted to bridge the gap between the desire to maintain ecological balance and harmful interference with ecosystems.

Chemical and biological characteristics of reclaimed soils in the Most ŕegion (Czecg Reooublic)

open access: yesPlant, Soil and Environment, 2003
Soil organic carbon content [Corg], pHH2O, pHKCl and microbiological characteristics (microbial biomass carbon [CMB], extracellular microbial carbon [CEX], respiration, ammonification, and nitrification) were studied in 11 reclaimed soils, where the ...

Whole-Genome Sequencing and Biotechnological Potential Assessment of Two Bacterial Strains Isolated from Poultry Farms in Belgorod, Russia

open access: yesMicroorganisms, 2023
Bacteria, designated as A1.1 and A1.2, were isolated from poultry waste based on the ability to form ammonia on LB nutrient medium. Whole genome sequencing identified the studied strains as Peribacillus frigoritolerans VKM B-3700D (A1.1) and Bacillus ...

Growth Yields in Bacterial Denitrification and Nitrate Ammonification [PDF]

open access: yesApplied and Environmental Microbiology, 2007
ABSTRACT Denitrification and nitrate ammonification are considered the highest-energy-yielding respiration systems in anoxic environments after oxygen has been consumed. The corresponding free energy changes are 7 and 35% lower than that of aerobic respiration, respectively. Growth yield determinations with pure cultures of

Microbial regulation of nitrogen dynamics along the hillslope of a natural forest

open access: yesFrontiers in Environmental Science, 2015
Topography affects the soil physicochemistry, soil N dynamics, and plant distribution and growth in forests. In Japan, many forests are found in mountainous areas and these traits are often highly variable along steep slopes.

Nutrient Solution from Aqueous Extracts as an Alternative to Fertigation in Hydroponic

open access: yesHorticulturae, 2023
The reintegration of agro-waste into the same agriculture site fulfils the objective of the European Bio-Economy Strategy: to reduce transport costs, waste volume, and the need for mineral fertilizers.

The influence of grassing and harvest management on microbial parameters after arable land setting-aside

open access: yesPlant, Soil and Environment, 2002
During the years 1998-2000 soil chemical (Corg, Nt, pH), textural (sand, silt clay) and microbiological (microbial biomass carbon - CMB, microbial extracellular carbon - CEX, respiration, ammonification, nitrification) characteristics were tested on ...
