Effect of the addition of invert sugar on the production of cephalosporin C in a fed-batch bioreactor
(Brazilian Society of Chemical Engineering, 1998-12-01)
Cephalosporin C, a b -lactam antibiotic, is the starting molecule for industrial production of semi-synthetic cephalosporins. The bioprocess for its production is carried out in batch stirred and aerated tank reactors ...

Removal of ammonium via simultaneous nitrification-denitrification nitrite-shortcut in a single packed-bed batch reactor
(ELSEVIER SCI LTD, 2009)
A polyurethane packed-bed-biofilm sequential batch reactor was fed with synthetic substrate simulating the composition of UASB reactor effluents. Two distinct ammonia nitrogen concentrations (125 and 250 mg l(-1)) were ...
Simplified Mathematical Model for an Anaerobic Sequencing Batch Biofilm Reactor Treating Lipid-Rich Wastewater Subject to Rising Organic Loading Rates
(MARY ANN LIEBERT INC, 2009)
This study proposes a simplified mathematical model to describe the processes occurring in an anaerobic sequencing batch biofilm reactor (ASBBR) treating lipid-rich wastewater. The reactor, subjected to rising organic ...
Application of dynamic optimization techniques for poly(b̃- hydroxybutyrate) production in a fed-batch bioreactor
(American Chemical Society, 2010-02)
Poly(b̃-hydroxybutyrate), PHB, is a microbial biopolymer produced by bacteria under unbalanced culture conditions. Such unbalanced conditions can be easily reached in a fed-batch bioreactor; therefore, it is important to ...
Tools for improving feeding strategies in a SBR with several species
(Springer, 2014)
This paper analyzes feeding strategies in a
sequential batch reactor (SBR) with the objective of
reaching a given (low) substrate level as quickly as possible
for a given volume of water. Inside the SBR, several
species ...
Nitrification and aerobic denitrification in anoxic-aerobic sequencing batch reactor
(Elsevier, 2016-01)
The aim of this study was to evaluate the feasibility of achieving nitrogen (N) removal using a lab-scale sequencing batch reactor (SBR) exposed to anoxic/aerobic (AN/OX) phases, focusing to achieve aerobic denitrification. ...
Performance of anoxic -oxic sequencing batch reactor for nitrification and aerobic denitrification
(IntechOpen, 2019)
The biological nitrogen removal (BNR) involves two processes: nitrification and denitrification. Denitrification occurs almost exclusively under facultative anaerobic or microaerophilic conditions; however, aerobic ...
