You are working on determining the Oxygen Transfer Rate (OTR) and Oxygen Uptake Rate (OUR) in a bioreactor. You perform two set of experiments in a 3L bioreactor. During the first set of experiments, you fill the bioreactor with water only, you remove all the dissolved oxygen and start sparging it with air at the specified agitation speeds and air flowrate. Which of the following methods could be used to estimate the volumetric oxygen transfer coefficient (kLa)? C*: saturation concentration of dissolved Oxygen CL: concentration of dissolved Oxygen at any given time Question options: kLa is the slope of a ln(C* ) versus time plot kLa is the slope of a CL versus time plot -kLa is the slope of a ln(C* - CL) versus time plot kLa is the slope of a ln(C* - CL) versus time plot
