A perfusion-capable microfluidic bioreactor for assessing microbial heterologous protein production

Lab Chip. 2015 Jul 21;15(14):2918-22. doi: 10.1039/c5lc00443h.

Abstract

We present an integrated microfluidic bioreactor for fully continuous perfusion cultivation of suspended microbial cell cultures. This system allowed continuous and stable heterologous protein expression by sustaining the cultivation of Pichia pastoris over 11 days. This technical capability also allowed testing the impact of perfusion conditions on protein expression. This advance should enable small-scale models for process optimization in continuous biomanufacturing.
