“…In addition, the latter author reported a significant increase in the microbial degrading activity through the cyclical starvation periods. This latter feature agrees well with findings reported by other authors (Subrahmanya Sastry et al 1994;Kaya et al 1996;Watanabe et al 2000). Survival under non-operating conditions may be an important factor for biotreatment operations as starvation periods are a common scenario found in the industrial environment resulting from interruptions of the industrial process leading to periods with no effluents to be treated.…”

Using a continuous enrichment technique, a bacterial consortium capable of degrading 4-chlorophenol (4-CP) was obtained from the rhizosphere of Phragmites australis. A granular activated carbon (GAC) biofilm reactor was established using this consortium, and the degradation of 4-CP was investigated under continuous flow operation using a feed of 20-50 mg l(-1) with a hydraulic residence time of 17 min over a 6-month period. Chloride liberation occurred throughout the operation, and the reactor had 4-CP removal efficiencies of 69-100%. Periods of lower performance were attributed to clogging of the column with biomass and the formation of channels. Subsequently, the immobilized biofilm was subjected to a starvation period of 5 months, after which its degradative capacity was still maintained. The microbial consortium was characterized during the continuous flow experiment and dynamic population changes were observed throughout. One isolate recovered from the biofilm was shown to be capable of degrading 4-CP as a sole carbon and energy source.

The integral method for the analysis of kinetic data was used to describe the removal of carbon dioxide dissolved in the aqueous phase of a tubular photobioreactor by Aphanothece microscopica Nägeli. The effects of the carbon dioxide concentration (3, 15, 25, 50 and 62%), light intensity (960, 3000, 6000, 9000 and 11,000 lux) and temperature (21.5, 25, 30, 35 and 38.5 • C) were considered using a central composite design, aiming to determine the most efficient system conditions. Response surface methodology showed the importance of the operational parameters of the photobioreactor on the kinetics of carbon dioxide removal, a good fit of the first order kinetic model to the experimental data being obtained.

vi "Um dia, a Terra vai adoecer. Os pássaros cairão do céu, os mares vão escurecer e os peixes aparecerão mortos na correnteza dos rios. Quando esse dia chegar, os índios perderão o seu espírito. Mas vão recuperá-lo para ensinar ao homem branco a reverência pela sagrada terra. Aí, então, todas as raças vão se unir sob o símbolo do arco-íris para terminar com a destruição. Será o tempo dos Guerreiros do Arco-Íris."
