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.

Type II alveolar epithelial cell in vitro culture in aerobiosis
European Respiratory Journal, 1988A method of Type II alveolar epithelial cell culture in aerobiosis has been developed. Isolation of Type II cells was performed by digesting guinea-pig lung tissue with crude trypsin and elastase and using discontinuous Percoll density gradients. The Type II cells, as identified by light and electron microscopy, were cultured in aerobiosis for up to ...

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.

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 ...

Aerobiosis and the hemoprotein content of photosynthetic bacteria
Archiv f�r Mikrobiologie, 1959Rhodospirillum rubrum and Rhodopseudomonas spheroides, grown under various degrees of illumination, aeration, and iron deprivation, have been assayed for their content of cytochrome c, RHP, catalase, total iron, bacteriochlorophyll, and carotenoids.

Cytolysin gene expression in Enterococcus faecalis is regulated in response to aerobiosis conditions
Molecular Genetics and Genomics, 2003Here we investigate the expression of cylL(L)and cylL(S), the genes that encode the structural subunits of the cytolysin/haemolysin of Enterococcus faecalis, in response to aerobiosis conditions. Haemolysis assays of E. faecalis strains cultured under aerobic and anaerobic conditions revealed three different haemolytic phenotypes, one of which ...

Isolated rat and guinea pig hearts show, during perfusion with aequeous salt solutions, myocardial edema formation of different degree. The extent of tissue fluid accumulation is dependent on the species, the osmolality, and the oxygen partial pressure of the perfusion medium.

Aerobiosis Increases the Genomic Guanine Plus Cytosine Content (GC%) in Prokaryotes
Journal of Molecular Evolution, 2002The huge variation in the genomic guanine plus cytosine content (GC%) among prokaryotes has been explained by two mutually exclusive hypotheses, namely, selectionist and neutralist. The former proposals have in common the assumption that this feature is a form of adaptation to some ecological or physiological condition.

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.
