How to tune recombinant protein production in E. coli for enhanced production of biopharmaceuticals?
Oliver Spadiut
TU Wien, Austria
Strong induction of recombinant protein production in E. coli can lead to agglomeration of inactive product, inclusion bodies
(IBs), and also imposes a high metabolic burden which can result in cell death. We developed a feeding strategy using glucose
as primary carbon source, lactose as secondary carbon source and inducer to tune recombinant protein expression which leads to
higher yields of soluble and active product. We successfully applied this system for the production of several biopharmaceuticals.
This new feeding approach allows expression of complex products as soluble and active protein that usually results in insoluble and
inactive inclusion bodies. Cell viability and growth can be prolonged by this approach which leads to higher overall yields and thus
lower production costs. Thus, our strategy might make E. coli a more attractive host for the production of biopharmaceuticals in the
future. The audience will get to know a platform technology for the enhanced expression of biopharmaceuticals in E. coli to accelerate
bioprocess development and yield higher product titers.
