Characterization of packed-bed in the downcomer of a concentric internal-loop airlift bioreactor
(2022-04-01)
A packed-bed basket containing corn cob powder was used for the adaptation of a concentric-tube airlift reactor for enzymatic reactions. The bed was inserted in the downcomer region of the bioreactor generating a decrease ...
Customized design of electronic noses placed on top of air-lift bioreactors for in situ monitoring the off-gas patterns
(Springer, 2012-06)
A specially designed electronic nose was coupled to an air-lift bioreactor in order to perform on-line monitoring of released vapors. The sensor array was placed at the top of the bioreactor sensing the headspace in ...
Specific growth rate estimation in (fed-)batch bioreactors using second-order sliding observers
(Elsevier, 2011-08)
This paper addresses the estimation of specific growth rate of microorganisms in bioreactors using sliding observers. In particular, a second-order sliding observer based on biomass concentration measurement is proposed. ...
Performance of a sulfidogenic bioreactor inoculated with indigenous acidic communities for treating an extremely acidic mine water
(Facultad de Ingeniería y Tecnología, 2019)
Mining contributes to water pollution through the generation and uncontrolled release of sulfuric acid and metalliferous drainage (AMD). While sulfate reducing bacteria have been used for the bioremediation of AMD, one of ...
