[PDF] parameters of fermentation process

What are the six parameters of fermentation?

The six parameters are: 1. Preliminary Investigations 2. Scale Up 3. Culture Preservation 4. Feedstocks for Fermentation Processes 5. Fermenter Design and Operation 6. Downstream Processing. 1. Preliminary Investigations: The starting point for a fermentation process is the discovery that a microorganism makes a useful product.

What is the fermentation process?

Fermentation is an anaerobic process in which sugar molecules are broken down into simpler molecules. Some of the commonly known products of the fermentation process are bread, beer, wine, etc. The fermentation process is affected by a number of factors, including pH, temperature, nutrient concentration, and availability.

How to scale-up a fermentation process?

The traditional method for scale-up of a fermentation process involves determining the reactor geometry, impeller speed, and aeration rate of the large-scale bioreactor on the basis of the experimental results of the lab-scale bioreactor. The most common method of scale-up is based on maintaining geometric similarity of bioreactors.

What is the formula for continuous fermentation?

.. Fig. 5.20? Microbial growth, substrate consumption, and product production for continuous fermentation dx = µ X ? X D = 0 at steady state dt Then ? X = X D; ? = D (For one stage continuous fermentation) (. Fig. 5.21).
