Fed-batch operationPreliminary research on fed-batch mode was conducted on shake-flask fermentation for 72 h. The feed substrate was SIW with different total solids (20, 30, 40 and 50 g/L) and the feed was added at 10-h interval (based on DO recorded during batch fermentation in bioreactor).

Simple exponential feeding and inferential methods are examined, as are newer methods based on fuzzy control and neural networks. The repeated fed-batch process had the advantages of reducing the time and cost for seed culture and inoculation between each fermentation cycles. A fermentor is fed at hr with a sterile substrate. In the absence of outlet flow, the volume in the batch-fed fermentor will increase linearly. This Demonstration shows the time-dependent behavior of four functions: the biomass concentration, the substrate concentration, the product concentration, and the volume in the reactor.

Microorganisms are inoculated and grown under batch regime for a certain amount of time, then nutrients are added to the fermenter in increments throughout the remaining duration of fermentation to feed them. operation was ﬁrst called a fed-batch culture or fed-batch fermentation.1,2 It is also known as Zulaufverfahren in German or ryukaho2 (a ﬂow addition method) in Japanese.

Research output: Thesis › Doctoral Thesis (compilation) XCell ATF ® Fed-Batch applications address specific productivity and throughput challenges faced during different bioprocessing stages. To help maximize Fed-Batch prductivity and throughput, Repligen optimized N-1 Perfusion and High Productivity Harvest, using XCell ATF ® technology. Fed-batch fermentation is a production technique between batch and continuous fermentation and is so called as a semicontinuous system with relative operational simplicity and superior industrial feasibility (10 – 12). Most biopharmaceutical production platforms are based on fed-batch cell culture protocols, which can support high volumetric productivity while maintaining low operational complexity (1). The industry is interested in developing or refining high-titer cell culture processes to meet increasing market demands and reduce manufacturing costs (2).
