Presence does not imply activity: DNA and RNA patterns differ in response to salt perturbation in anaerobic digestion
(BioMed Central, 2016-10-20)
Background
The microbial community in anaerobic digestion is mainly monitored by means of DNA-based methods. This may lead to incorrect interpretation of the community parameters, because microbial abundance does not ...
A novel control strategy for single-stage autotrophic nitrogen removal in SBR
(Elsevier, 2014-08-27)
A novel feedforward–feedback control strategy was developed for complete autotrophic nitrogen removal in a sequencing batch reactor. The aim of the control system was to carry out the regulation of the process while keeping ...
Model-based optimization biofilm based systems performing autotrophic nitrogen removal using the comprehensive NDHA model
(2018-03-10)
Completely autotrophic nitrogen removal (CANR) can be obtained in single stage biofilm-based bioreactors. However, their environmental footprint is compromised due to elevated N2O emissions. We developed novel spatially ...
N2O emissions from a single-stage partial nitritation/anammox granule-based reactor – a model based assessment
(2017)
Completely autotrophic nitrogen removal (CANR) can be obtained in single stage granule-based bioreactors. However, their environmental footprint is compromised due to elevated N2O emissions. In this study we develop and ...
Enhanced ammonia removal at room temperature by pH controlled partial nitrification and subsequent anaerobic ammonium oxidation
(Taylor & Francis, 2014)
The Anammox based processes are suitable for the treatment of wastewaters characterized by a low carbon to nitrogen (C/N) ratio. The application of the Anammox process requires the availability of an effluent with a ...
Designing mixed-culture bioprocesses by means of bioenergetics models
(2017-11)
Mixed culture fermentations (MCFs) are recognised as an inexpensive means to produce high-added-valueproducts
from low-grade biomass. However, developing a new bioprocess based on this technology is a
challenging task. ...
Computer-Aided Design of Active Packaging/Food System for extended shelf life
(2018-09-07)
Common dynamic models of active packaging are focused on the mass transfer of the antimicrobial agents. Nevertheless, the interaction of the antimicrobial agent with the food microorganisms is usually neglected, despite ...
Electron bifurcation mechanism and homoacetogenesis explain products yields in mixed culture anaerobic fermentations
(Elsevier, 2018-05-11)
Anaerobic fermentation of organic wastes using microbial mixed cultures is a promising avenue to treat residues and obtain added-value products. However, the process has some important limitations that prevented so far any ...
Electron bifurcation mechanism and homoacetogenesis explain product yields in mixed culture anaerobic fermentations
(2017-10-19)
Anaerobic fermentation of wastes with mixed cultures is a promising avenue to treat residues while producing added-value products. But thus far, the lack of control and prediction of the microbial community behaviour hinders ...
Bringing frequency response analysis closer to Chemical Engineering
(2020)
Process control has traditionally been considered a difficult subject among chemical engineering students. A particular aspect that differentiates process control from process design related courses is also that the former ...
