| Abstract: | Statistically-based experimental designs were used to optimize a chemically defined medium for the S-adenosyl-L-me-thionine(SAM) production by recombinant Pichia pastoris. The concentrations of ammonium sulfate, methanol and L-me-thionine were optimized using central composite design and response surface analysis. SAM production was increased by 60% when the optimization strategy was applied. Furthermore, the relationship between the amount of SAM synthetase and the accumulation of SAM was studied. |
