Abstract Bacteriohopanepolyols with A-ring methyl substituents are bacterial lipid biomarkers that are presently known to originate from just a few specific taxa. When preserved in ancient rocks, the fossilized hydrocarbon skeletons of these molecules have the potential to provide biogeochemical records of those taxa and their respective physiologies.

Energetic irrelevance of aerobiosis for S. cerevisiae growing on sugars
Molecular and Cellular Biochemistry, 1979The net benefit that Saccharomyces cerevisiae obtains from aerobiosis as compared to anaerobiosis has been studied. For this purpose yeasts with different respiratory capacities have been obtained by growing them in batch cultures on different substrates.

Relation of aerobiosis and ionic strength to the uptake of dihydrostreptomycin in Escherichia coli
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1980Aminoglycoside antibiotics exhibit a markedly reduced antibacterial activity under anaerobic conditions. Anaerobiosis or inhibitors of electron transport produced an extensive decrease in the uptake of dihydrostreptomycin in Escherichia coli K-12. Uptake of proline or putrescine were only slightly impaired under anaerobic conditions in the presence of ...

Characterization of E. coli MG1655 and frdA and sdhC mutants at various aerobiosis levels
Journal of Biotechnology, 2011Depending on the availability of oxygen, Escherichia coli is able to switch between aerobic respiratory metabolism and anaerobic mixed acid fermentation. An important, yet understudied, metabolic mode is the micro-aerobic metabolism at intermediate oxygen availabilities. The relationship between oxygen input, physiology and gene expression of E.

[Heart surgery in normothermia and aerobiosis: apropos of 530 patients].
Archives des maladies du coeur et des vaisseaux, 1993Between February and October 1991, 530 consecutive patients underwent myocardial revascularization or valvular surgery with warm continuous antegrade and retrograde cardioplegia (37 degrees C). Three hundred and thirty three patients had isolated myocardial revascularization, 159 valvular surgery alone and 25 had combined valvular and coronary bypass ...

Brettanomyces/Dekkera yeasts grow in wine and their presence is often associated with spoiling activity. In this report, we investigated on the influence of different conditions of aerobiosis on growth and fermentation behaviour of these spoilage yeasts in wine.

The aim of the present study was to improve the viability of marginal livers from non‐heart beating donors upon cold preservation using two different techniques for the provision of tissue aerobiosis. Livers from male Wistar rats (250–300 g bw) were harvested after 60 min of cardiac arrest, flushed via the portal vein with 20 mL of heparinized Ringer's

[Effect of acetate on the growth of Escherichia coli during aerobiosis and anaerobiosis].
Mikrobiologiia, 1985The dynamics of acetate accumulation was studied in Escherichia coli K-12 batch cultures with a substrate addition. At pH 7.0, the growth stopped at 150 mmoles of acetate per litre of the medium under the aerobic conditions or at 35 mmoles of acetate per litre of the medium under the anaerobic conditions. Experiments with extraneous addition of acetate
