Polymer-based controlled-release fed-batch microtiter plate – diminishing the gap between early process development and production conditions

open access: yesJournal of Biological Engineering, 2019
Background Fed-batch conditions are advantageous for industrial cultivations as they avoid unfavorable phenomena appearing in batch cultivations. Those are for example the formation of overflow metabolites, catabolite repression, oxygen limitation or ...

The scale-up of microbial batch and fed-batch fermentation processes [PDF]

open access: yesJournal of Biotechnology, 2007
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]

open access: yes, 2016
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]

open access: yes, 2013
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]

open access: yes, 2011
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

open access: yesFrontiers in Bioengineering and Biotechnology, 2023
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.
