Anaerobiosis and Mutations Can Reduce Susceptibility of Pseudomonas aeruginosa to Tobramycin Without Reducing the Cellular Concentration of the Antibiotic [PDF]
PathogensChronic infections of Pseudomonas aeruginosa are commonly treated with tobramycin. During infections, the bacteria can exist under conditions of oxygen deprivation that render them less susceptible to this antibiotic.

Bacterial membrane vesicles restore gut anaerobiosis. [PDF]
NPJ Biofilms MicrobiomesInflammation damages the epithelial cell barrier, allowing oxygen to leak into the lumen of the gut. Respiring E. coli and other Enterobacteriaceae produce proinflammatory lipopolysaccharide, exacerbating inflammatory bowel disease. Here we show that respiring membrane vesicles (MV) from E. coli ameliorate symptoms in a mouse model of gut inflammation.

Impact of Anaerobiosis on Expression of the Iron-Responsive Fur and RyhB Regulons
MBio, 2015 Iron, a major protein cofactor, is essential for most organisms. Despite the well-known effects of O2 on the oxidation state and solubility of iron, the impact of O2 on cellular iron homeostasis is not well understood.

Anaerobiosis of fluid mud [PDF]
Nature, 1976 OBSERVATIONS in estuaries have reported the existence of ephemeral deposits of semi-fluid mud1,2 extending several metres from the bottom. These muds differ from ‘mud’ as normally understood in that although they form definite boundaries with the overlaying water mass they have a lower solid content and settle, if at all, only very slowly.

Incomplete anaerobiosis as a cause of metronidazole 'resistance'. [PDF]
Journal of Clinical Pathology, 1978 Clostridium welchii, used as a control, was found to grow well in a microaerophilic jar used for campylobacters but appeared resistant to a metronidazole disc although the campylobacter was sensitive. Minimum inhibitory concentrations for six strains of Cl. welchii were up to 64-fold higher in these conditions than when grown anaerobically.

Frontiers in Microbiology, 2018 Current notion presumes that only one protein is encoded at a given bacterial genetic locus. However, transcription and translation of an overlapping open reading frame (ORF) of 186 bp length were discovered by RNAseq and RIBOseq experiments. This ORF is

Fungal Biodeterioration and Preservation of Miniature Artworks [PDF]
Journal of Fungi, 2023 The study of biodeterioration is an important issue to allow the best conservation and prevent the decay of cultural heritage and artworks. In Naples (Italy), a particular museum (Museodivino) preserves the miniature artworks representing Dante’s Divine ...

Effect of Anaerobiosis on Staphylococcal Nuclease Production
Journal of Bacteriology, 1968 Five strains ofStaphylococcus aureuswere examined quantitatively for the production of nuclease under aerobic and anaerobic conditions. Hydrolysis of deoxyribonucleic acid and ribonucleic acid was detected by measuring the release of acidsoluble nucleotides spectrophotometrically.

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.

Metagenomic evidence clarifies the texture-dependent cascading effects of organic degradation on soil hypoxia and N2O emission [PDF]
Frontiers in MicrobiologyIntroductionSoil pore-scale aeration is a crucial yet often overlooked factor influencing the effectiveness of nitrous oxide (N2O) emission mitigation strategies.
