Microbial protein out of thin air : fixation of nitrogen gas by an autotrophic hydrogen-oxidizing bacterial enrichment [PDF]

, 2020
For the production of edible microbial protein (MP), ammonia generated by the Haber-Bosch process or reclaimed ammonia from waste streams is typically considered as the nitrogen source.

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer

FEBS Letters, EarlyView.
Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

Influence of pre-crop and root architecture on the mobilization of non-exchangeable NH4+

Plant, Soil and Environment, 2014
It is well established that non-exchangeable NH4+ is an important N source for plants. However, release from clay minerals only occurs when the NH4+ concentration of the mineral environment declines below a certain level.

Factors affecting ammonium uptake in streams - an inter-biome perspective [PDF]

, 2003
The Lotic Intersite Nitrogen experiment (LINX) was a coordinated study of the relationships between North American biomes and factors governing ammonium uptake in streams. Our objective was to relate inter-biome variability of ammonium uptake to physical,

Leaves play a central role in the adaptation of nitrogen and sulfur metabolism to ammonium nutrition in oilseed rape (Brassica napus) [PDF]

, 2010
Background: The coordination between nitrogen (N) and sulfur (S) assimilation is required to suitably provide plants with organic compounds essential for their development and growth.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Determination of NH4+ and NO3- Adsorption and Desorption Capacities of Biochars Produced at Different Temperatures

Turkish Journal of Agriculture: Food Science and Technology
This study investigates the adsorption and desorption capacities of corn cob biochars produced at three different pyrolysis temperatures. Adsorption experiments were conducted using ammonium (NH4+) and nitrate (NO3-) solutions at concentrations 5, 10, 25,

The impact of nitrogen fertilizer injection on kernel yield and yield formation of maize

Plant, Soil and Environment, 2014
In field experiments over three vegetation periods (2010-2012) we studied impact of the CULTAN (controlled uptake long term ammonium nutrition) method on yield and yield parameters of kernel maize. The field experiments were conducted at three sites with

Spatial Distribution and Mobility of Nutrients on Sand Mulching Soil for Fertigated Green Bean Crops under Greenhouse Conditions in Southern Spain: (I) Macronutrients

Agronomy, 2021
Information about the nutrients distribution in sand-mulched soils is rather scarce; therefore, the aim of this experiment was to determine the spatial distribution and mobility of macronutrients in the wet bulb zone in two sand-mulched soils (a ...
