Optimization of phosphate-limited autoinduction broth for two-stage heterologous protein expression in Escherichia coli

Autoinducible, two-stage protein expression leveraging phosphate-inducible promoters has been recently shown to enable not only high protein titers but also consistent performance across scales from screening systems (microtiter plates) to instrumented bioreactors. However, to date, small-scale prod...

520 |a Autoinducible, two-stage protein expression leveraging phosphate-inducible promoters has been recently shown to enable not only high protein titers but also consistent performance across scales from screening systems (microtiter plates) to instrumented bioreactors. However, to date, small-scale production using microtiter plates and shake flasks relies on a complex autoinduction broth (AB) that requires making numerous media components, not all amenable to autoclaving. In this report, the authors develop a simpler media formulation (AB-2) with just a few autoclavable components. AB-2 is robust to small changes in its composition and performs equally, if not better, than AB across different scales. AB-2 will facilitate the adoption of phosphate-limited two-stage protein expression protocols
