Can a process be regulated based on a gas analysis?
A gas analysis is excellently suited to regulate bioprocesses as this analysis method is very resistant to failure. By using BlueSens sensors precise measurement values can be analysed directly in the exhaust line. Thereby parameters such as e.g. the oxygen uptake rate (OUR or OTR), carbon dioxide production rate (CER or CTR) and the resulting respiration quotient (RQ) can be calculated. Then, to prevent oxygen limitations, the gassing rate and the rotation speed of the fermenter agitator can be adjusted. By the well-directed substrate feed (based on the RQ) unwanted effects (e.g. Crabtree) can be prevented.
