On the basis of mode of operation, a bioreactor may be classified as batch, fed batch or continuous (e.g. a continuous stirred-tank reactor model). An example of a continuous bioreactor is the chemostat. Fed-batch culture was proven to be superior to batch or continuous cultures for the production of 2,3-BDL. Indeed, the highest concentration of 2,3-BDL recently reported (150 g l −1) was obtained in a fed-batch culture of K. pneumoniae with a productivity of 4.21 g l −1 h −1 [32].

Savings were also seen when the ATF cell density dropped to a threefold increase over the fed-batch strategy for most combinations of titres and production scales.

In batch fermentation, microorganisms are inoculated to a fixed volume of medium in a fermentor. With microbial growth, the nutrients are gradually consumed and by-products accumulate.

This bibliography was generated on Cite This For Me on Thursday, January 4, 2018 The fed-batch process is started per typical procedure (Step A) in Figure 2.Once the peak cell density is achieved, Day 10 in this example, fresh media is pumped in at a set flow rate (Step B). 2008-01-07 · In a way it is really difficult to define strictly if the bioreactor is 'batch' 'fed batch' or 'continuous' bioreactor just based on the feeding mode BATCH REACTOR-----If the bioreactor is only fed once, and no more feeding after that we say that the bioreactor is operating on batch mode. The bioreactor will be allowed to run till completion. Fed-batch fermentation is an upgraded version of the batch fermentation process wherein the substrate is introduced in increments at different time intervals throughout the fermentation process.

Batch Fermentation. Ø Microorganism is inoculated into a fixed volume of medium. Ø As the growth takes place, the nutrients are consumed and the product of growth accumulates in the fermenter. Ø Product of growth may be of two types: (a) Biomass and (b).

Fed batch culture gives greater product yields than batch culture technique. Disadvantage: Chance of contamination of culture is higher in fed-batch than batch culture technique.

Insight: The sequential scheduling of batch feeds in pure batch operations presumes complete knowledge and a lack of variability in raw materials and batch behavior. The fed-batch control system enables the dissolved oxygen and substrate concentration and pH to be more constant throughout the batch.
