Common pathways and outliers in glucose catabolism across Trypanosomatidae

The FEBS Journal, EarlyView.
Trypanosomatid parasites, including Trypanosoma sp., Leishmania sp., Phytomonas sp., and Vickermania sp., share a common motif: a metabolism built around the glycosome, a unique peroxisome‐derived organelle housing the first steps of glycolysis. Yet, these organisms have evolved remarkably diverse strategies to catabolize glucose, excreting distinct ...

Anaerobiosis in saturated soil aggregates : modelling and experiment

, 1995
International audienceA model of anaerobiosis based on gas diffusion and microbial respiration is proposed for soil aggregates. Unlike previous models, it accounts for the dependency of O-2 consumption on O-2 and CO2 concentrations and, consequently, on ...

Oxygen availability strongly affects chronological lifespan and thermotolerance in batch cultures of Saccharomyces cerevisiae

Microbial Cell, 2015
Stationary-phase (SP) batch cultures of Saccharomyces cerevisiae, in which growth has been arrested by carbon-source depletion, are widely applied to study chronological lifespan, quiescence and SP-associated robustness.

The Role of torS and torT Transcription in Driving a Bet‐Hedging Strategy for Trimethylamine N‐Oxide Reductase Expression in Escherichia coli

Molecular Microbiology, EarlyView.
Low basal activity of divergent promoters driving transcription of the trimethylamine N‐oxide (TMAO) sensor TorT and kinase TorS is integral to an O2‐regulated bet‐hedging strategy for continued E. coli growth upon the onset of anaerobiosis. This, along with repression by IscR, promotes noise in the TorS to TorT ratio, which is critical for adaptation ...

Light-induced photosynthetic electron transfer upon anaerobiosis in Chlamydomonas : kinetics, electron sinks and setup of a fluorescence screen to identify new players. [PDF]

, 2012
In Chlamydomonas reinhardtii, prolonged anaerobiosis leads to the expression of various fermentative pathways. Among them, oxygen-sensitive hydrogenases (hyd) catalyze the reduction of protons from reduced ferredoxin resulting in the production of ...

Haloferax volcanii Immersed Liquid Biofilms Develop Independently of Known Biofilm Machineries and Exhibit Rapid Honeycomb Pattern Formation

mSphere, 2020
The ability to form biofilms is shared by many microorganisms, including archaea. Cells in a biofilm are encased in extracellular polymeric substances that typically include polysaccharides, proteins, and extracellular DNA, conferring protection while ...

Metagenomic Evaluation of Oral Microbiota in Patients Affected by Oral Lichen Planus: A Pilot Study

Oral Diseases, EarlyView.
ABSTRACT Objective To characterize the oral bacterial and fungal microbiota of symptomatic oral lichen planus patients undergoing topical corticosteroid therapy and to explore microbial patterns potentially associated with subsequent oral candidiasis. Methods Twelve patients with clinically and histologically confirmed OLP were enrolled.

Effects of Antimitotic Agents, Temperature and Immersion Time on Chromosome Doubling Efficiency in Supersweet Corn (Zea mays L. var. saccharata)

Plant Breeding, EarlyView.
ABSTRACT Doubled haploid technology accelerates the development of fully homozygous maize lines compared with conventional selfing. However, specific protocols for supersweet corn (Zea mays L. var. saccharata), particularly regarding immersion time in antimitotic solutions and temperature during chromosome doubling, remain poorly defined.

The global anaerobic metabolism regulator fnr is necessary for the degradation of food dyes and drugs by Escherichia coli

mBio, 2023
The microbiome is an underappreciated contributor to intestinal drug metabolism with broad implications for drug efficacy and toxicity. While considerable progress has been made toward identifying the gut bacterial genes and enzymes involved, the role of

Plant mitochondrial function during anaerobiosis [PDF]

Annals of Botany, 2008
Under hypoxic conditions, plant mitochondria preserve the capacity to oxidize external NADH, NADPH and tricarboxylic acid cycle substrates. Nitrite serves as an alternative electron acceptor at the level of cytochrome oxidase, with possibly complex III and the alternative oxidase also being involved.
