Shake Flask fermentation is a cheapest ans simplest technique to grow bacteria or fungi, aerobically, in small volumes of nutrient broth. The broth is poured into erlenmeyer flasks equipped with cotton-wool stoppers, and autoclaved. After cooling, some microbes are "seeded" into the flask, and it is placed on a Shaker machine. The shaking agitates the content and so ensures aeration, so that the microbes could breathe.
