Microbial assay of N2 fixation rate, a simple alternate for acetylene reduction assay

MethodsX, 2018
Nitrogen is an essential element for living creatures in every ecosystem but nitrogen cannot be absorbed by the plant itself directly from the atmosphere, so for nitrogen, plant depends on both free living and symbiotic microbes present in the soil ...

Microbial response to nitrogen availability : preferential and adaptive community uptake

, 2010
This project was designed to assess the ability of natural sediment microbial communities and single species microbial populations to preferentially utilize inorganic forms of nitrogen (ammonium, NH4-N, and nitrate, NO3-N, specifically).

Nanocellulose Alleviates Intrahepatic Cholestasis of Pregnancy via Gut Microbiota‐Mediated Bile Acid Homeostasis

Advanced Science, EarlyView.
Nanocellulose, derived from microcrystalline cellulose (MCC) through sulfuric acid hydrolysis or mechanical grinding to produce CNC or CNF, was tested in a rat ICP model. Particularly, CNF improved gut microbiota composition, reduced secondary bile acid metabolism, and restored bile acid homeostasis through modulation of the gut–liver axis.

Microbial response mechanisms of organic nitrogen substitution for optimizing tobacco yield and quality: the key role of 50% organic nitrogen

Frontiers in Microbiology
IntroductionPrecise matching of nutrient supply with plant demand in tobacco cultivation is crucial for achieving high yield and superior quality. Traditional chemical fertilizer application modes have obvious limitations, and although organic nitrogen ...

Decoding IGLL5 Mutation‐Mediated BCR Signaling: A Novel Mechanism of CD8+ T Cell Exhaustion and Ocular MALT Lymphoma Progression

Advanced Science, EarlyView.
OAML harbors recurrent IGLL5 mutations that reinforce CD79A/CD79B‐associated BCR signaling. Mechanistic analysis of the S47G and A54G variants reveals induction of CXCL10/CXCL11, enhanced CD8+ T‐cell recruitment, and exhaustion‐associated dysfunction, supporting an immune‐tolerant niche.

Nitrogen deposition does not change stochastic processes of soil microbial community assembly under climate warming in primary forest

Ecological Indicators
Soil microbial communities are essential for ensuring forest health, however, the influences of global change on soil microbial communities and their ecosystem functions remain unclear. Here, we explored the influences of experimental warming (3 °C above

Community ecology of denitrifying bacteria in arable land [PDF]

, 2008
Denitrifying bacteria comprise a functional guild that under anaerobic conditions is able to use nitrogenous compound for respiration. Agricultural soils are often fertilized with nitrogen, and the reduction of nitrate and nitrite to nitric oxide ...

Diversity of Pharmaceuticals Enhances Antibiotic Resistance in the Invertebrate Gut via Biofilm‐Mediated Mechanisms

Advanced Science, EarlyView.
Pharmaceutical diversity acts as an independent driver of antibiotic resistance in soil invertebrates. While bulk soil remains unaffected, the collembolan gut microbiome exhibits significant resistance gene enrichment under complex chemical exposure and diurnal warming.

Distinct genes and microbial communities involved in nitrogen cycling between monsoon- and westerlies-dominated Tibetan glaciers

Nature Communications
The Tibetan Plateau (TP) glaciers are influenced by monsoon and westerlies. They are highly sensitive to climate change, with atmospheric nitrogen deposition significantly impacting microbial communities and functions.
