Fermenter are of two types 1. Aerobic fermenter 2. Anaerobic fermenter

When air is pumped into a sunken ship, it acts as a floater. The air boosts the sunken ship's buoyancy and helps the trapped water to escape.
An aerobic ferment er is one in which there is provision for the introduction of sterile air into the reaction. The sterile air is introduced into the interiors of the fermenter through an attachment called a sparger. Air is bubbled through. The bubbles are then dispersed throughout the reactor by an impeller (a mixing apparatus that stirs the entire reaction contents in the fermenter).
The fermenter is surrounded by a jacket of cold water to regulate the temperature of the reaction medium.
It gets pumped.
Air. Imagine that.
In the process of inflating a balloon, air is pumped in to increase the density of the balloon. In scuba diving, a diver adjusts the air in their buoyancy control device to control their density and buoyancy in the water. Air is pumped into a hot air balloon to increase its density and provide lift for flight.
Helium is typically pumped into balloons because it is lighter than air and gives the balloon its ability to float.
They rise to the surface when air is pumped IN. They sink when air is let out
