What are industrial fermenters?
Large vessels which have an air supply providing oxygen for respiration, stirrers or gas bubbles, a water-cooled jacket around the outside and sensors to monitor both pH and temperature.

Why do industrial fermenters have stirrers or gas bubbles?
To keep the microorganisms spread out and to provide an even temperature.

Why do industrial fermenters have a water-cooled jacket around the outside?
Because the respiring microorganisms release energy which heats the contents.
