A general kinetic and mass transfer model to simulate the growth of baker’s yeast in bio-reactors [1-3]
The bakers’ yeast production is normally performed starting from a small quantity of S. Cerevisiae which is added to a liquid solution of essential nutrients, at a suitable temperature and pH level. Once the cell population has grown enough, it is transferred into a larger bioreactor for a new growth stage; 7 or 8 stages are usually performed to reach a satisfactory production amount. Therefore, the bioreactors volume changes from 1dm3 to 150 m3.
