متن کاملAeration and de-aeration at bottom aeration devices on spillways
Aeration devices are introduced along chute spillways and at bottom outlets to prevent cavitation damage in high velocity flows. Bottom aerators are characterised by large quantities of air entrained along the jet interfaces but also by a strong de-aeration process near the impact of the water jet with the spillway bottom. In this paper, the aeration and de-aeration occurring respectively in th...
متن کاملContinuous-Culture Responses of Candida shehatae to Shifts in Temperature and Aeration: Implications for Ethanol Inhibition.
Temperature and aeration shifts were used to perturb steady-state continuous cultures to determine the effects of ethanol on xylose metabolism by Candida shehatae. The accumulation of ethanol exerted a delayed inhibitory effect on the specific rate of substrate utilization. A second effect was also observed in which the specific rate of xylitol production increased at the expense of the specifi...
متن کاملEffect of Aeration on Growth and Aflatoxin Production by Aspergillus flavus in Submerged Culture.
Aspergillus flavus ATCC 15517 produced up to 212 mg per liter of total aflatoxin in submerged culture in aerated (3,000, 6,000, 9,000, and 12,000 ml/min) and agitated medium in 14-liter fermentors with 10 liters of medium consisting of 2% yeast extract and 10% sucrose. Aflatoxin production increased with time. A maximum of 212 mg/liter was produced at 9,000 ml/min aeration, whereas the yield de...
متن کاملEffects of toxicity, aeration, and reductant supply on trichloroethylene transformation by a mixed methanotrophic culture.
The trichloroethylene (TCE) transformation rate and capacity of a mixed methanotrophic culture at room temperature were measured to determine the effects of time without methane (resting), use of an alternative energy source (formate), aeration, and toxicity of TCE and its transformation products. The initial specific TCE transformation rate of resting cells was 0.6 mg of TCE per mg of cells pe...
