Gassing Strategies

O2 Enrichment

This is a gassing strategy uses a 3 | 2-way solenoid valve to direct either an air or O2 flow to the sparger. A manual flow meter visually indicates and controls the flow rate. O2 is pulsed via solenoid valve, when required to maintain the dissolved oxygen setpoint. Air is not provided at this time. You can optionally integrate mass flow controllers to measure and control the total gas flow rate via manual adjustment or automatically in conjunction with the controller, based on the signal of the pO2 probe and the selected setpoint.

Advanced Additive Flow

You can direct air, O2 , N2 and CO2  to the sparger and to the overlay. Flow meters visually indicate the flow rate for each gas. Add an additional gas flow path to the sparger or overlay outlet. Select optional mass flow controllers for each flow path, and switch gases between overlay and sparger. The detailed design of the Advanced Additive Flow gassing approach depends on your particular Biostat® bioreactor system and configuration.

Additive Flow

Controls the flow rate of air and O2 individually, (N2 and CO2 also possible but not shown) to a single output, either a sparger or overlay.

High-cell density

Employing the Biostat® D-DCU 10-3 it is demonstrated in this study, that this fermenter meets the requirements for an E. coli high-cell density fermentation.

Standardized Qualification of Biostat® D-DCU

The performance capabilities of a bioreactor, which are substantially influenced by its design and thus, its bioengineering characteristics, are crucial in order to choose a system matching the specific process requirements.

In order to guarantee a reliable comparison between existing bioreactor systems the DECHEMA guideline was published by an expert group as a standardized method required for the determination of the key bioengineering data.

Here the Biostat® D-DCU 30-3 and 100-3 are characterized according to this recommendation.
