Aerobiosis

 

life in the presence of free oxygen. Aerobiosis is characteristic of the overwhelming majority of animals, plants, and microorganisms. All aerobic organisms, as distinguished from anaerobic organisms, obtain energy for their life activities through oxidative processes. Their enzyme systems are capable of oxidation-reduction reactions with molecular oxygen as the final acceptor of electrons. In the overwhelming majority of aerobes, respiration is accompanied by the absorption of molecular oxygen and the emission of carbon dioxide gas; some microorganisms do not carry oxidation to completion (for example, acetic-acid bacteria, some fungi, and others). The aerobic type of metabolism and energy exchange is more effective than anaerobiosis, since it ensures the generation of a larger quantity of energy per mole of substance.

For the parameter Maximal HR recorded during the game, the athletes from FC Dinamo have recorded an average maximal HR of 193.5 bpm, while the athletes from CSS1 have recorded a value of 202.7 bpm; it can be concluded that the achieved values fall within the maximal higher aerobiosis effort (relative steady state/stamina/ ergostasis) (figure 4).
(71) This might reflect the fact that DvM enzyme had been purified under strict anaerobiosis and was active as isolated, whereas Dg enzyme was prepared under aerobiosis as an inactive unready state, which could be activated only after prolonged incubation under [H.sub.2].
En los casos de encefalitis los cultivos bacterianos se realizaron a partir de macerados de medula oblonga cultivados en agar sangre Columbia a 37[grados]C en aerobiosis. Las muestras negativas a dichos cultivos fueron reprocesadas: luego de 15 dias de enriquecimiento en frio a 4[grados]C se volvieron a cultivar en agar sangre Columbia como se menciono.
Se cultivo en agar fresco Charcoal (Difco) con sangre de caballo, incubada en aerobiosis a 35[grados]C por 6 dias.
