Mass Transfer Performance of Ethanol Removal by CO2 Stripping in Different Pneumatic Bioreactors
(2020-04-01)
The hydrodynamics and mass transfer characteristics of ethanol stripping with CO2 were evaluated for a 2.0-L pneumatic bioreactor operated in bubble column (BC), concentric-tube airlift (CTA), and split-cylinder airlift ...
ANALYSIS OF THE PREDICTIVE DMC CONTROLLERPERFORMANCE APPLIED TO A FEED-BATCH BIOREACTOR
(Brazilian Society of Chemical Engineering, 1997)
Effects of photobioreactor configuration, nitrogen source and light intensity on the fed-batch cultivation of Arthrospira (Spirulina) platensis. Bioenergetic aspects
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
Bioenergetic analysis may be applied in order to predict microbial growth yields, based on the Gibbs energy dissipation and mass conservation principles of the overall growth reaction. The bioenergetics of the photoautotrophic ...
Removal of pharmaceuticals and ecotoxicological changes in wastewater using Trametes versicolor: A comparison of fungal stirred tank and trickle-bed bioreactors
(2021)
Hospital wastewater is loaded with pharmaceutically active compounds (PhACs), which sometimes end up in the environment unaltered due to the lack of effective and specific treatments. The use of white rot fungi, specifically ...
A bioreactor model system specifically designed for Tetrahymena growth and cholesterol removal from milk
(Springer, 2007-02)
This work describes the configuration and operation of a bioreactor system especially designed for Tetrahymena cultivation and its use for milk improvement, particularly cholesterol elimination by the action of this cell. ...
Enhanced metal recovery by efficient agglomeration of precipitates in an up-flow fixed-bed bioreactor
(2021-07-15)
In this study, a single-stage up-flow fixed-bed sulfidogenic bioreactor was operated for 288 days (six stages), treating mine-impacted water at different concentrations of nickel (Ni), cobalt (Co) and other associated ...
