MetabolomicsInhibition of anaerobic digestion by various ammonia sources resulted in subtle differences in metabolite dynamics

The impact of ammonia on anaerobic digestion performance and microbial dynamics has been extensively studied, but the concurrent effect of anions brought by ammonium salt should not be neglected. This paper studied this effect using metabolomics and a time-course statistical framework. Metabolomi...

MetabolomicsIntegrated analysis of transcriptome and metabolome reveals molecular responses to ammonia stress in the gills of Litopenaeus vannamei under low-salinity conditions

High ammonia nitrogen stress significantly compromises the survival of Litopenaeus vannamei under low-salinity conditions, posing a common challenge in low-salinity aquaculture. However, existing studies predominantly focus on ammonia nitrogen responses unde...

MetabolomicsDiscovery of novel metabolic pathways and regulatory mechanisms of ammonia-oxidizing bacteria in organic materials stabilization

Background Ammonia-oxidizing bacteria (AOB) play a crucial role in the microbiome of the global nitrogen cycle. Yet, their regulatory functions in the metabolic pathways involved in organic material stabilization (OMS) are not fully understood. We employed...

MetabolomicsPhysiological, Transcriptomic, and Metabolomic Insights into Ammonia-Nitrogen Stress in the Hepatopancreas of Litopenaeus vannamei Acclimated to Low Salinity
High ammonia nitrogen stress markedly decreases the survival rate of Litopenaeus vannamei under low-salinity conditions. Nevertheless, most available studies have primarily focused on the ammonia nitrogen response of small-sized shrimp under single-stressor exposure or normal seawater salinity. The ...

TranscriptomicsExpression analysis of the starvation and recovery response of Nitrosomonas europaea ATCC 19718
Investigation of the whole genome gene expression level changes relative to exponential phase growth in Nitrosomonas europaea ATCC19718 after 12 hours ammonia starvation, 144 hours ammonia starvation, and 20 minutes following ammonia addition to starved cells. The ammonia monooxygenase of chemolitho...

ProteomicsComparative proteomics of three species of ammonia-oxidizing bacteria under ammonia starved and ammonia replete conditions
In this experiment, we used advanced proteomics techniques to discern differences in energy allocation between three strains of ammonia oxidizing bacteria: Nitrosomonas europaea, Nitrosomonas ureae, and Nitrosospira multiformis, during ammonia starved and ammonia replete conditions. Replicate cultur...

TranscriptomicsExpression profiling of P. stutzeri A1501 treated with 20mM ammonia shock for 10 min
A whole genome DNA microarray was used to undertake a global transcriptional analysis of nitrogen fixation and ammonium repression in Pseudomonas stutzeri A1501. The aim of this study was to identify the genes that are up-regulated under nitrogen fixation conditions and rapidly down-regulated as soo...

TranscriptomicsTranscription Response by sulfur chemolithoautotroph Thiomicrospira crunogenato dissolved inorganic carbon and ammonia limitation
The hydrothermal vent gammaproteobacterium Thiomicrospira crunogena inhabits an unstable environment and must endure dramatic sweeps in habitat chemistry. This sulfur chemolithoautotroph responds to changes in dissolved inorganic carbon (DIC; = CO2 + HCO3- + CO3-2) availability with a carbon concent...
