Feasibility of a Sequencing Reactor Operated in Batch and Fed-batch Mode Applied to Nitrification and Denitrification Processes
(ASOC QUIMICOS, 2009)
The objective of this work was to study the operational feasibility of nitrification and denitrification processes in a mechanically stirred sequencing batch reactor (SBR) operated in batch and fed-batch mode. The reactor ...
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 ...
EVALUATION OF BACTERIAL-CONTAMINATION IN A FED-BATCH ALCOHOLIC FERMENTATION PROCESS
(Rapid Science PublishersLondonInglaterra, 1994)
Modeling and simulation of cephalosporin C production in a fed-batch tower-type bioreactor
(Humana Press Inc, 2001-03-01)
Immobilized cell utilization in tower-type bioreactor is one of the main alternatives being studied to improve the industrial bioprocess. Other alternatives for the production of beta -lactam antibiotics, such as a ...
Production of clavulanic acid and cephamycin C by Streptomyces clavuligerus under different fed-batch conditions
(Brazilian Society of Chemical Engineering, 2013-06-01)
The effect of carbon source and feeding conditions on the production of clavulanic acid (CA) and cephamycin C (CephC) by Streptomyces clavuligerus was investigated. In fed-batch experiments performed with glycerol feeding, ...
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 ...
Influence of nitrogen source and sucrose concentration on inulinase production by Kluyveromyces marxianus in fed-batch fermentation
(Academic Journals, 2011-09-26)
This work studied the influence of nitrogen source and sucrose concentration in the feeding medium for biomass and inulinase production by Kluyveromyces marxianus var. bulgaricus. The results show that the best nitrogen ...
Fed-Batch Production of Tetanus Toxin by Clostridium Tetani
(JOHN WILEY & SONS LTD, 2010)
This study deals with the effects of the initial nitrogen source (NZ Case TT) level and the protocol of glucose addition during the fed-batch production of tetanus toxin by Clostridium tetani. An increase in the initial ...
Optimal control strategy for fed-batch enzymatic hydrolysis of lignocellulosic biomass based on epidemic modeling
A mathematical optimal control strategy for feeding operation was developed for fed-batch enzymatic hydrolysis of dilute acid pretreated lignocellulosic biomass based on a modified epidemic model. Cellulose conversion was ...
