Graph of the Bioreactor

1. The relation between pressure of oxygen and stirrer  at 23:50 to 23:53 is that when the pressure of oxygen is going down, the stirrer is increase as well  as temperature.It means that the oxygen is being consumed by the yeast. As the dissolved oxygen level decrease, the stirrer will play its role that is to agitate faster so that the yeast will get adequate amount of oxygen. So, the yeast would not die.

2. at duration  23 : 26 :20 . As temperature increase , pressure of oxygen increase.
