Figure 4From: A novel fed-batch based cultivation method provides high cell-density and improves yield of soluble recombinant proteins in shaken culturesA schematic picture of the EnBaseĀ® Flo cultivation principle. Phase 1 = controlled cultivation in mineral salt medium with a low concentration of complex additives (peptones, yeast extract). Phase 2 = induction with IPTG and addition of complex nutrients (booster mixture). Phase 2a of increased growth rate is followed by Phase 2b of low growth rate and slow production of soluble protein.Back to article page
