Fermenter Control

Batch fermentation is a process where all the substrate and nutrients are added at zero time or soon after inoculation takes place, and the vessel is allowed under a controlled environment to proceed until maximum end product concentration is achieved. 

Batch fermentations are the most commonly used and simplest models to study the fermentation activity of colonic microbes. 

These batch fermenters are usually anaerobic sealed bottles with pure cultures, defined mixed cultures or fecal slurry, and are used to study the effects of added NSP on the microbes and their fermentation activity. 

Batch fermentation of oleaginous microorganisms is generally conducted with a high C/N ratio to induce the extra carbon into lipids accumulation at limiting nitrogen concentration conditions. 

batch fermentation were mainly focused on nutritional and physiological parameters. 

Batch fermentation is highly dynamic yet a closed system in which all the medium components, except gases such as oxygen, acid or base for pH control, and antifoaming agents, are placed in the reactor at the start of the cultivation. 

Batch fermentation, a cost-effective process, has been expensively used for the commercial production of various value-added products; during this process, nutrients were provided to the reactor while cells and products remained in the reactor until the end of fermentation
