Otr fermentation
WebApr 7, 2024 · This is explained by a further decrease in the inoculation volume from 4% of the starting volume to 0.9%. Additionally, the DO also dropped and remained below the setpoint after 8 h of fermentation . As in small pilot scale, it is assumed that the geometry of the bioreactor and the configuration of the stirrer resulted in a lower OTR. WebThe oxygen uptake rate is calculated as follows: OUR = k L a ( [O2]* - [O2]) – d [O2] / d t. where k L a is the volumetric mass-transfer coefficient for the respective shake flask in the respective operating conditions, and [O2]* is the saturation concentration. d [O2] / d t (= OTR, oxygen transfer rate) is used to calculate the current ...
