The scale-up of microbial batch and fed-batch fermentation processes [PDF]
Publisher Summary The scale-up of single-celled aerobic microbial fermentation processes is complicated that can lead to unpredictable process performance. However, this is not due to the introduction of fluid dynamic generated stresses (or so-called “shear damage”), whether arising from agitator generated turbulence or bursting bubbles, rather it is

Strategies in fed-batch cultivation on the production performance of Lactobacillus salivarius I 24 viable cells [PDF]
The potential use of fed-batch cultivation (FBC) for improvement of the production of Lactobacillus salivarius I 24 biomass for subsequent use as probiotics was studied using a 2-L stirredtank bioreactor. Three different constant feeding rates (0.1, 0.05,

Downstream processing of high chain length polysialic acid using membrane adsorbers and clay minerals for application in tissue engineering [PDF]
Polysialic acid (polySia) is a carbohydrate polymer of varying chain length. It is a promising scaffold material for tissue engineering. In this work, high chain length polySia was produced by an Escherichia coli K1 strain in a 10-L bioreactor in batch ...

Optimization of cyclosporin A production by Beauveria nivea in continuous fed-batch fermentation [PDF]
To develop the effective control method for fed-batch culture of cyclosporin A production, we chose fructose, L-valine and (NH4)2HPO4 as feeding nutrients and compared their productivities in relation to different concentrations.

Enhanced iturin a production in a two-compartment biofilm reactor by Bacillus velezensis ND
In this study, a two-compartment biofilm reactor was designed for iturin A production. The biofilm reactor consists of a stirred-tank fermentor containing exclusively suspended cells and a packing column where the biofilm is attached.
