Semisolid state fermentation of Baker's yeast in an air-fluidized bed fermentor

In an attempt to grow microorganisms other than fungi using a solid-state fermentation process, a model system of Baker's yeast (Saccharomyces cerevisiae) was cultured in an air-fluidized bed fermentor. A semisolid potato mixture (pretreated with alpha-amylase) was used for the substrate in thi...

Summary:In an attempt to grow microorganisms other than fungi using a solid-state fermentation process, a model system of Baker's yeast (Saccharomyces cerevisiae) was cultured in an air-fluidized bed fermentor. A semisolid potato mixture (pretreated with alpha-amylase) was used for the substrate in this highly aerated system. The growth of Baker's yeast in this air-fluidized bed process was easily controllable and very reproducible. Once feasible moisture levels and air flow rates were determined, the independent variables studied were the amount of the enzyme used for digesting the potato starch, the size of the yeast inoculum, and the concentration of the added defined medium.
