Hydrogen may be considered a potential fuel for the future since it is carbon-free and oxidized to water as a combustion product. Bioconversion of synthesis gas (syngas) to hydrogen was demonstrated in continuous stirred tank bioreactor (CSTBR) utilizing acetate as a carbon source. An anaerobic photosynthetic bacterium, Rhodospirillum rubrum catalyzed water-gas shift reaction which was applied ...

Viral vectors facilitate the delivery of genetic material to living cells for potential treatment multiple diseases. With recent regulatory approvals, rapid growth in demand viral vector-based products highlights need proven, scalable manufacturing solutions that can fully meet this and ultimately increase availability treatments. Pall’s AllegroTM STR stirred-tank bioreactor addresses scalabili...

Stirred tanks are widely used in process industries for blending of singleand/or multiple-phase fluids, which often involves mass and/or heat transfer, chemical reactions, etc. Deep knowledge of flow field in the stirred tank is necessary to carry out these unit operations efficiently. As a result, extensive investigations of the flow in stirred tanks have been conducted over the past several d...

This paper presents a comparative study of Continuous Stirred Tank Reactor concentration control using Particle Swam Optimization and Bacterial Forging Optimization. Continuous stirred tank reactor plays a very important role in process industry. This paper presents the optimal design of PID controller based on Particle Swarm Optimization and Bacterial Forging Optimization. The first step is th...

Experiments Most publications of velocity measurements in stirred tanks concern measurements in single-phase flows. An excellent review of these studies was made by Ranade and Joshi (1990a). Literature concerning velocity measurements in aerated stirred tanks is scarcer however. An overview of literature is given in Table 1. Lu and Ju (1987) used constant temperature anemometry (CTA) in order t...

Hemicellulosic biomass from olive-tree pruning (OTPB) was used as a raw material in order to produce hemicellulosic hydrolysate be fermented with the non-traditional yeast Candida guilliermondii FTI 20037 obtain ethanol and xylitol. The main objectives of this research were study most relevant kinetic parameters involved bioconversion process correlation between stirred-tank bioreactor agitated...

Manufacture of red blood cells (RBCs) from progenitors has been proposed as a method to reduce reliance on donors. Such a process would need to be extremely efficient for economic viability given a relatively low value product and high (2 × 1012 ) cell dose. Therefore, the aim of these studies was to define the productivity of an industry standard stirred-tank bioreactor and determine engineeri...
