Fermenters are used for the biotechnological production of enzymes and other products using bacteria, yeast and cell cultures. For educational purposes a bubble bioreactor used in this experiment is a more convenient and ecomical alternative to commercial fermenters. To demonstrate how fermenters work, in this experiment molasses which is a waste product of sugar production is fermented in the so-called batch process.
