Answer 2

A sparger adds air that moves up through  the culture medium in a bioreactor.

• Spargers in common are an industry method designed to efficiently deliver ideal gas into a tank or column flotation cell to ensure bubbles are uniformly spread in the tank or a flotation cell.
• It is typically tough to achieve favourable mass transmission of ideal gases such as oxygen or carbon dioxide in bioreactor systems.
• To be specific, oxygen is poorly soluble in water, and even less so in cell culture and in broths for fermentation.  
• In a bioreactor, the practical use of a porous metal sparger significantly improves mass transfer rates.
