Comparison between batch and fed-batch production of rhamnolipid by Pseudomonas aeruginosa

This paper presents a comparison between batch and three different sets of fed batch fermentations forrhamnolipid production by Pseudomonas aeruginosa. The batch run was performed with 500 ml of culturemedium having the initial glycerol and sodium nitrate concentrations of 30 and 8.3 g/l, respectively. For a fedbatch run with nitrogen source in feed, 250 ml of the nitrogen exc...

Self-Organizing Modelling of Biotechnological Batch and Fed-Batch Fermentations

The paper at hand deals with an approach for the automatic generation of dynamic nonlinear process models. These models are obtained from experimental process data as well as from theoretical biological and chemical reeections using the ideas of Genetic Programming for the supervision and coordination of the symbolic model structure during the automatic development.

Fed-Batch Production of a Fermented Beverage Containing Vitamin B12

Production of fermented functional foods containing micronutrients is required for their health beneficial properties. The impact of 11 process variables on vitamin B12 production in a dairy beverage containing propionic acid was investigated. Propionibacterium freudenreichii ssp. shermanii was applied in a 3-l fermentor in the fed-batch fermentation system. The most suitable conditions for...

Phytase production by the unconventional yeast Pichia anomala in fed batch and cyclic fed batch fermentations

A marked enhancement in the production of cell-bound phytase in Pichia anomala was achieved in cyclic fed batch fermentation (47333 UL -1 ) in comparison with that in batch (11569 UL -1 ) and fixed volume fed batch (36911 UL -1 ) fermentations in cane molasses medium. Phytase productivity was sustainable in cyclic fed batch fermentation over seven days, and therefore, this mode of fed batch fer...
