Suitable conditions inside an industrial fermenter are extremely important. For example, the enzymes must be kept around their optimal temperatures or else they will be slow or will denature. They also need their optimum pH. Air inside must be regulated so that oxygen is constantly put in and CO2 constantly taken out. It also needs to be sterile inside the chamber, so steam is put inside to kill off any bacteria inside.

The temperature can be regulated by the use of a plate which gets hotter or less hot which controls the temperature.

There is a mixer that ensures there are no lumps and to evenly distribute the substances.
