aerobiosis

Enumeration was conducted after incubation in aerobiosis at 37[degrees]C for 72h (ASHRAF & SHAH, 2011).

Despues de la incubacion a 30[grados]C, en aerobiosis hasta observar el crecimiento de colonias, estas fueron caracterizadas macroscopicamente, registrandose la textura y el color, se cultivaron por duplicado en viales con el mismo agar de procedencia, se incubaron a 30 [grados]C, en aerobiosis, hasta observar crecimiento y se llevaron a refrigeracion 4[grados]C (Guzman et al.

The aeration system used to maintain the system under aerobiosis causes cysts and oocysts to remain suspended in the liquid mass; subsequently they are transported trapped or not into the biological floc, which is concentrated in the clarifier after the aeration tank.

Los microorganismos mesofilos totales se incubaron (Raypa 150L Modelo B-292 I-150, Raypa, Espana) en condiciones de aerobiosis a 30[grados]C durante 72 horas (h) [20].

pylori from the spiral to the coccoid form has a protective function against environmentally disadvantageous factors such as increases in oxygen concentration (aerobiosis), changes in pH (acidic or alkaline), elevated temperature, reduced nutrient content, prolonged in vitro incubation, and exposure to bio-cides (9-11).

The lower aerobic stability of silages, containing high content of lactic acid and soluble carbohydrates, occurs because microorganisms such as yeasts have the ability to use these compounds in aerobiosis as a substrate for the production of C[O.sub.2], water and heat with consequent increase in pH of the mass allowing the growth of other undesirable microorganisms that are less tolerant to low pH such as filamentous fungi and spore-producing bacteria (Woolford, 1990).
