With the “static gassing-out” method, an oxygen sensor is installed in the bioreactor to measure the dissolved oxygen concentration in the medium. The characterization is done with water, but any liquid media can be used. The oxygen concentration of the medium is set to zero by degassing with nitrogen. See more The performance of microorganisms and cells is highly dependent on the conditions and nutrient supply during each process and also on the kLa in the bioreactor. In most cases, the process conditions for a suitable environment … See more The advantages of a high air flow rate and high stirring speeds are clear to see. A bench-scale bioreactor with a standard motor is only limited … See more For a successful aerobic cultivation, a good oxygen transfer is vital. It can be increased by: 1. Creating a bigger surface of gas bubbles (kLa) by increasing gas flow and stirrer speed and by adding baffles 2.

WebFeb 26, 2016 · Determination of the volumetric oxygen transfer coefficient ( kLa) is very important for bioreactor design and process analysis. Among all the methods available, the gassing-out technique is one of the simplest and most widely used for this task. Weband C* is the oxygen saturation concentration in the liquid phase at the gas-liquid interface). K La estimation was done using the static gassing out method (3). As explained earlier, the volume of the bioreactor was going to be high because of the higher dilution. Hence there is a large volume of culture that is away from the impellor.
