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...

TranscriptomicsTranscriptional responses of yeast to preferred and non-preferred nitrogen sources in C-lim chemostat cultures
Aerobic, glucose-limited chemostat cultures of Saccharomyces cerevisiae grown with six different nitrogen sources were subjected to transcriptome analysis. The use of chemostats enabled an analysis of nitrogen-source-dependent transcriptional regulation at a fixed specific growth rate. A selection o...

MetabolomicsRich organic nitrogen impacts clavulanic acid biosynthesis through the arginine metabolic pathway in Streptomyces clavuligerus F613-1

Clavulanic acid (CA) is the preferred clinical drug for the treatment of infections by β-lactam antibiotic-resistant bacteria. CA is produced by Streptomyces clavuligerus, and although there have been many reports on the effects of carbon and nitrogen sources on CA production, the mechan...

ProteomicsProteomic profiling of Levilactobacillus brevis CRL 2013 grown in different nitrogen sources.
This project aimed to characterize the proteomic profile of Levilactobacillus brevis CRL 2013, a γ-aminobutyric acid (GABA)-producing lactic acid bacterium, grown under different nitrogen sources (CDMg, CDMgC, CDMgYE). Proteins were extracted from cultures, digested with trypsin, and analyzed using ...

GenomicsNitrogen regulatory protein C couples nitrogen stress response and stringent response in nitrogen starved Escherichia coli.
We show that NtrC couples the Ntr stress response and stringent response in N starved E. coli, which appears to be a conserved adaptive strategy employed by many bacteria to manage conditions of nutritional adversity. N starved Escherichia coli initiate the nitrogen regulation (Ntr) stress response ...

TranscriptomicsComparison of Aspergillus fumigatus transcriptome grown on selected nitrogen sources
Transcriptome of A. fumigatus shifted from ammoniumtartrate to different nitrogen sources and incubated for a defined time was compared. After 16h preculture, the fungus was transferred into fresh medium containing ammonium tartrate, sodium nitrate, proline or bsa as nitrogen source. After 1h, fungu...

TranscriptomicsTranscription profiling by array of the complete GlnR nitrogen-response regulon in Mycobacterium smegmatis
BACKGROUND: Nitrogen is an essential element for bacterial growth and an important component of biological macromolecules. Consequently, responding to nitrogen limitation is critical for bacterial survival and involves the interplay of signalling pathways and transcriptional regulation of nitrogen a...
