Can I use Bacto CD Supreme Fermentation Production Medium (FPM) for seed stock generation?

Bacto CD Supreme Fermentation Production Medium (FPM) can be used for seed stock generation. This is the recommended usage of Bacto CD Supreme FPM to ensure optimal results.

I'm interested in achieving faster growth. How can I ensure successful transition from LB Broth to Bacto CD Supreme Fermentation Production Medium (FPM)?

To achieve faster growth, additional glucose may be added at 2-5 g/L to the glycerol-containing Bacto CD Supreme Fermentation Production Medium (FPM).

Is a carbon source required for use with Bacto CD Supreme Fermentation Production Medium (FPM)?

Yes, glycerol and/or glucose are required for use with Bacto CD Supreme Fermentation Production Medium (FPM).

Is amino acid supplementation required for my E. coli strain when using Bacto CD Supreme Fermentation Production Medium (FPM)?

A detailed supplementation table can be found in the Bacto CD Supreme Fermentation Production Medium (FPM) user guide (https://assets.thermofisher.com/TFS-Assets/LSG/manuals/MAN0024960_BactoCDSupremeFPM_UG.pdf), for various E. coli strains. The genotype of your specific E. coli strain may also be provided by your vendor with supplementation guidance.

My E. coli strain is a derivative of DH10B or Top10 carrying delta (ara-leu) mutation. What supplementation do I need when using Bacto CD Supreme Fermentation Production Medium (FPM)?

A detailed supplementation table can be found in the Bacto CD Supreme Fermentation Production Medium (FPM) user guide (https://assets.thermofisher.com/TFS-Assets/LSG/manuals/MAN0024960_BactoCDSupremeFPM_UG.pdf), for various E. coli strains. L-leucine amino acid supplementation may be required, starting with a concentration of 0.5 g/L and optimized further.

Does Bacto CD Supreme Fermentation Production Medium (FPM) support the growth of other bacteria besides E. coli strains?

Bacto CD Supreme Fermentation Production Medium (FPM) has primarily been evaluated and developed using multiple E. coli strains. Bacto CD Supreme FPM may support the growth of other bacteria through additional studies and analysis by the customer with the bacteria species.
