Aerobiosis and the hemoprotein content of photosynthetic bacteria
Archiv f�r Mikrobiologie, 1959 Rhodospirillum 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.

Aerobiosis and anaerobiosis during diving by western grebes: An optimal foraging approach
Journal of Theoretical Biology, 1989 It is widely assumed that anaerobic diving is inefficient, and yet anaerobic dives are regularly observed in nature. We develop a model of diving, using a dynamic programming approach, that assumes dives are made to capture food. The essence of the model is that while aerobic diving is energetically efficient (in terms of glucose expended per mol of ...

Basic Research in Cardiology, 1982 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.

The independence of photosynthesis and aerobiosis from sterol biosynthesis in bacteria
Phytochemistry, 1980Abstract Sterols were present in neither of two representative species of photosynthetic bacteria, Rhodopseudomonas spheroides and Chromatium vinosum. These organisms were grown under conditions commonly viewed as anaerobic. However, such conditions did not prevent Saccharomyces cerevisiae from biosynthesizing sterols, although they did induce ...

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 ...
