recombinant human interferon alpha 2a (rhifn α -2a) production and cell growth were monitored in a set of genetically modified e. coli strains (msd1519, msd1520, msd 1521, msd 1522, msd 1523) producing rhifn α -2a. the growth was followed at od 600 nm, changes in cell physiology were detected by pyrolysis mass spectrometry (pyms) of cell biomass and recombinant protein production was determined...
