Abstract: | Fermentation is a very important bioprocess for the production of drugs, food products, beverage and for animal cell line culture etc. The substrates used in these processes are expensive. So on‐line monitoring of contamination in a fermentation process is very essential in industries. A new method for contamination detection is being proposed in this paper. This is a software‐based method. In this new method, the state variables of the process are used to detect contamination of the process. |
