On-Line Measurement of Dissolved Methane Concentration During Methane Fermentation in a Loop Bioreactor
A dissolved methane sensor based on silicone tube was designed, constructed and optimized.The silicone tube diameter, silicone tube length and helium flow rate (as the carrier gas(were considered as process parameters to be optimized.A continuous stream of helium (50 mL/min) was directed through the tubing, sweeping out the...
متن کاملMeasuring Dissolved Oxygen Concentration in Aquaculture
(DO) is considered the most important water quality variable in fish culture. In the broadest sense, however, dissolved oxygen concentration is no more important than other environmental variables because any factor that is outside the range tolerated by fish can cause stress or death. What makes dissolved oxygen concentration so important in intensive fish culture is the speed with which it ca...
متن کاملPrediction of dissolved oxygen and carbon dioxide concentration profiles in tubular photobioreactors for microalgal culture
A model is developed for prediction of axial concentration profiles of dissolved oxygen and carbon dioxide in tubular photobioreactors used for culturing microalgae. Experimental data are used to verify the model for continuous outdoor culture of Porphyridium cruentum grown in a 200-L reactor with 100-m long tubular solar receiver. The culture was carried out at a dilution rate of 0.05 h-1 appl...

متن کاملResponse coefficient analysis of a fed-batch bioreactor to dissolved oxygen perturbation in complementary cultures during PHB production
BACKGROUND Although the production of poly-beta-hydroxybutyrate (PHB) has many biological, energetic and environmental advantages over chemically synthesized polymers, synthetic polymers continue to be produced industrially since the productivities of fermentation processes fr PHB are not yet economically competitive. Improvement of a PHB fermentation requires good understanding and optimizatio...
